6 Marks Questions

Question 1.
Examine the different areas of agreement and disagreement with respect to the model of economic development to be adopted in India after independence, (HOTS; Delhi 2016)
Answer:
Agreement of Economic Model After independence, there were lot of discussion with respect to the model of economic development to be adopted in India. ‘Development’ was about becoming more ‘modern’ and modern was about becoming more like the industrialised countries of the West.

Indian planners did not follow any of the two known models of development i.e. capitalist model of development and socialist model of development.

India adopted both elements of these models that is why Indian economy is called Mixed Economy. Private sectors and public sectors flourished well. In India, state controlled the key industries and provided industrial infrastructure.

Disagreement of the Economic Model A mixed economy was criticised by many scholars and they argued that the planners had refused the private sector with enough space and the stimulus to grow. The enlarged public sector provided powerful vested interests that built enough hurdles for private capital by way of installing the license and permit systems.

Some critics have opinion that the era of public sectors where poverty did not decline even number of poor were adversally increased. The public sector did not spend much money on health care and education.

The state intervened into areas where private sector made profits. The policy of state restricted import of goods and production in the domestic market. Little or no companion left the private sector with no incentive to improve their products and make them cheaper.

After all this criticism government adopted the policy of globalisation, liberalisation and privatisation in 1991. This policy is called new economy policy where private firms enjoy their independence and government interferes only in economic matters.

Question 2.
Assess the outcomes of the early phase of planned development in India. (All India 2016,2013)
OR
Assess the outcome of planned development towards the foundation of India’s economic growth and land reforms. Delhi 2011
Answer:
In 1938, Indian National Congress set-up a Planning Committee to formulate a plan for the development of India’s future. After independence in April, 1951 India adopted the planned development procedure. It was felt that the procedure of planned development created a sound economic development and land reform.

Some points which relates with the planned development towards the foundation of India’s economic growth and land reforms are mentioned below :

  1. In 1950, Government of India passed a resolution and set-up the Planning Commission to prepare a plan for the most effective and balanced utilisation of the countries resources.
  2. The Planning Commission initiated the process of development which would increase the living standard and provide new opportunities.
  3. According to the long term objectives laid originally, it was to double the per capita income and to raise communication standards by 70% by 1977.
  4. The First Five Year Plan brought with it an era of a planned country with total outlay of ? 2249 crore which had two fold aims.
  5. The revolution like green revolution attained the record of production of food up to 75.6 million tonnes.
  6. The Kerala model was also very effective in terms of land reforms, public distribution system, poverty alleviation, health and literacy rates.
  7. Zamindari systems was abolished, consequently, lands were distributed among the landless farmers.
  8. Also White Revolution and Blue Revolution raised the development of country.
  9. In 1990, we adopted the mixed economy due to this planning of development increased and allowed investment in public sectors also.
  10. Research work, technologies in field of agriculture has been adopted therefore, India became self sufficient in food.
  11. In 1991, Indian Government adopted the new economy policy i.e., globalisation, privatisation and liberalisation. It helped a lot in development. Thus, the planning led to India’s growth in terms of literacy, intrastructures moreover in GDP.

Question 3.
Describe briefly the composition and any four functions of the Planning Commission of India. (All India 2011)
Answer:
Composition of Planning Commission :

  • The Prime Minister of India is the chairman of the commission.
  • The commission has a deputy chairman.
  • The finance minister and planning minister are the ex-officio members of the commission.
  • The commission has four to seven full time expert members.

Four Functions of the Planning Commission are :

  1. To make an assessment of material, capital and human resources of the country and investigate the possibilities of augmenting them.
  2. To formulate a plan for the most effective and balanced utilisation of the country’s resources.
  3. To determine priorities and to define stages in which the plan should be carried out.
  4. To indicate the factors that retard economic development.

Note: Planning commission no more exists today. It has been replaced by NITI Aayog (National Institution for Transforming India).

Question 4.
What were the early initiatives taken by the Planning Commission for building a new India? (All India 2011)
Answer:
After the independence India was suffering from poverty, literacy rate was very low. Therefore, Government of India passed a resolution and set-up a Planning Commission in March 1950. The Planning Commission planned a structure of development in terms of five Years Plans and mixed economic policy.

First Five Year Plan The First Five Year Plan emphasised on agricultural sector, dams, irrigation facilities. It also increased the literacy rate. It focused on saving, therefore the per capita income was increased.

Second Five Year Plan The Second Five Year Plan focused on industrial development and infrastructural development. So that agricultural sector also grew to meet the demand of agricultural products in industries.

Mixed Economic Policy India adopted the mixed economic policy. Therefore, the two sectors private and public could do better in development of India. The state controlled the heavy industries and provided industrial infrastructure, regulated trade and some important intervention in agriculture. This all buildup a new India.

Question 5.
What was Green Revolution?
Mention its any two positive and any two negative consequences. (Delhi 2012,2008; All India 2011,2008)
Answer:
It was a governmental approach towards reforms in agricultural sectors to attain rapid growth in production of agriculture. Because Indian agriculture, which had been stagnant and asleep for centuries needed a revolution and this government initiative is known as green revolution. Its aim was to – ensure self-sufficiency in foodgrain production. It took place in Third Five Year Plan. It had some essentials

  • Use of chemical fertilisers.
  • Use of HYV seeds.
  • Use of better irrigation planning.
  • Use of developed tools for farming.

Positive Consequences
For merits of Green Revolution the two merits of Green Revolution were :

  1. After launching this revolution, India achieved self-sufficiency in food production. Poor farmers also get benefit from this revolution.
  2. Due to this, the states of Punjab, Haryana and Western Uttar Pradesh flourished more and here the living standards also improved.

Thus, first socially, then politically and economically the status of farmers in these states was risen.

  1. This revolution created a valley between poor farmer and richer ones. Discrimination and exploitation of poor farmers by the landlords became a wide set practice. Some political parties started politics on it and managed seats in Assemblies and Lok Sabha elections.
  2. This revolution also increased the power of middleman who worked as mediators between poor farmers and affluent landlords.

Therefore the middleman created a condition due to which farmers were impoverished. The political strength of the middleman also increased.

Negative Consequences
For merits of Green Revolution the two merits of Green Revolution were :

  1. After launching this revolution, India achieved self-sufficiency in food production. Poor farmers also get benefit from this revolution.
  2. Due to this, the states of Punjab, Haryana and Western Uttar Pradesh flourished more and here the living standards also improved.

Thus, first socially, then politically and economically the status of farmers in these states was risen.

Demerit/Negative Outcomes

  1. This revolution created a valley between poor farmer and richer ones. Discrimination and exploitation of poor farmers by the landlords became a wide set practice. Some political parties started politics on it and managed seats in Assemblies and Lok Sabha elections.
  2. This revolution also increased the power of middleman who worked as mediators between poor farmers and affluent landlords.

Value Based Questions [VBQs]

Question 1.
What led policy-makers to reduce the importance of state in India’s economy from 1980’s onwards? (Delhi 2008; All India 2008)
Answer:
The following facts are responsible which led policy-makers reduce the importance of state in India’s economy from 1980 onwards:

  1. The story of development in India took a significant turn from the end of 1960s. After Nehru’s death the Congress system encountered difficulties. Indira Gandhi emerged as a popular leader. She decided to further strengthen the role of the state in controlling and directing the economy.
  2. The period from 1967 onwards witnessed many new restrictions on private industry and the government announced many pro-poor programmes. These changes accompanied by an ideological tilt towards socialist policies.
  3. However, the consensus for a state-led economic development did not last forever. Planning did continue but its salience was significantly reduced.
  4. Between 1950 and 1980 the Indian economy grew at a sluggish per annum rate of 3 to 3.5 per cent. In view of the prevailing inefficiency and corruption in some public sector enterprises and the not-so-positive role of the bureaucracy in economic development, the public opinion in the country last the faith in many of these institution. Such lack of public faith led the policy-makers to reduce the importance of the state in India’s economy from the 1980 onwards.

Question 2.
Explain the main arguments in the debate that ensued between industrialisation and agricultural development at the time of Second Five Year Plan. (All India 2012)
OR
Examine the controversy regarding Agriculture vs Industry in India after the 2nd Five Year Plan. (Delhi (C) 2008)
Answer:
The dispute between the agriculture and industry are as follows:

  1. The Second Plan that is Nehru-MAllalanobis Plan emphasised on the heavy industries and focussed less on agricultural sector. It declared the socialist pattern of society as its goal. The Second Plan emphasised on savings and investment. A bulk of industries like electricity, railways steel etc developed.
  2. The Second Five Year Plan mainly believed in the scientific manner of research and believed in modernity. This may cause the decline of agriculture.
  3. The Second Plan led towards generating the employment and establishment of industries. Nehru-MAllalanobis Plan stated that through the industrialisation poverty alleviation is possible.
  4. Agriculture needed urgent attention because it was hit by partition. But plans were made on the pattern of land distribution.
    It focused on the land reforms as the key to the country’s development.
  5. The agricultural situation went from bad to worse in the 1960s. Between 1965 to 1967 many droughts occurred which led to food shortage and famine like conditions in many parts of the country.
  6. The Second Plan established Tata institute of Fundamental Research where talented young students were trained for working in nuclear power projects. Government did not establish any such research institution for agriculture.

Thus, these above controversies put government into cage and demanded an equal treatment. Hence, the Indian planners found balancing industry and agriculture really difficult.

Picture Based Question

Question 1.
Study the cartoon given below carefully and answer the questions that follow:
Political Science Class 12 Important Questions Chapter 12 Politics of Planned Development 1
(i) Identify and name the person who is holding the balancing beam between the public sector and the private sector.
(ii) Why has a big tilt towards the public sector been shown in the cartoon?
(iii) How did the over-emphasis on public sector adversely affect the Indian economy? (All India 2017)
Answer:
(i) Pt. Jawaharlal Nehru, the then Prime Minister of India.
(ii) A big tilt towards the public sector been shown in the cartoon because the government was in favour of mixed economy which added elements from both public and state models of economy. But the government provided much power to public sector. This

sector has powerful vested interests that created enough hurdles for private capital, especially by way of installing systems of licenses, permits for investment and also restricted import of goods.

(iii) The public sector exercised much power than private sector like controlled key heavy industries, provided industrial infrastructure, regulated trade and made crucial interventions in agriculture.

When much hurdles created by public sector for private capital and also restrict import of goods by state’s policy, there was not enough space and stimulus left for private sector to grow.

The state controlled more things than were necessary and this over-emphasis on public sector ultimately led inefficiency and corruption in the Indian economy.

Physical Features of India Class 9 Notes Social Science Geography Chapter 2 SST Pdf free download is part of Class 9 Social Science Notes for Quick Revision. Here we have given Physical Features of India Class 9 Geography Chapter 2 Notes.

Physical Features of India Class 9 Notes Social Science Geography Chapter 2

Since the previous 3 years’ examinations, the factual questions (Very Short Answer Type) have been asking relevant to various physical divisions of India consisting of the following topics :

  • Location
  • The Himalayan Mountains
  • The Northern Plains
  • The Peninsular Plateau
  • The Indian Desert
  • The Coastal Plains
  • The Islands.

Location

India has all major physical features of the Earth, i.e., mountains, plains, deserts, plateaus, and islands.

In India, the soil colour varies from place to place as it is formed from different types of rocks.

India has varied physical features whose formation can be explained on the basis of the ‘Theory of Plate Tectonics’.

According to the theory of Plate Tectonics, the seven major and minor plates that form the Earth’s crust keep moving, causing stress and thus leading to folding, faulting and volcanic activity.

The physical features of India can be grouped under the following physiographic divisions:

  • The Himalayan Mountains or the Northern Mountains
  • The Northern Plains or the Indo-Gangetic Plains
  • The Peninsular Plateau
  • The Great Indian Desert
  • The Coastal Plains
  • The Islands

The Himalayan Mountains

The Himalayas are young-fold mountains which are the loftiest and one of the most rugged mountain barriers of the world.

The Himalayas are 2400 km long, 400 km to 150 km wide from Kashmir to Arunachal Pradesh respectively.

The Himalayas have three parallel ranges in the longitudinal extent namely :

  • Great or Inner Himalayas also called Himadri.
  • Middle Himalayas or Himachal.
  • Outer Himalayas or Shiwaliks.

The Himalayas can be divided into four sections :

  • Punjab Himalayas – between Indus and Satluj.
  • Kumaon Himalayas – between Satluj and Kali.
  • Nepal Himalayas – between Kali and the Tista.
  • Assam Himalayas (Eastern Himalayas) – Between Tista and the Dibang (Tsangpo).

The Northern Plains

The Northern Plains spread over an area of 7 lakh sq. km, 240 km long and 240 km to 320 km broad.

The rivers that flow to the plains from the mountains are involved in depositional work.

The difference in relief causes the Northern Plains to have four regions.

  • Bhabar – Adjacent to the foothills of Shiwaliks, a narrow 8 to 16 km wide belt of pebbles and boulders.
  • Bangar – Older alluvial plain which rises above the level of the flood plains.
  • Khadar – Newer and younger alluvial of the flood plains deposited by the rivers flowing down the plain.
  • Tarai – Lies adjacent to Bhabar region, composed of newer alluvium and is thickly forested.

The Peninsular Plateau

The Peninsular Plateau is the tableland formed due to the breaking and drifting of the Gondwanaland.

The plateau consists of two broad divisions, namely, the Central Highlands and the Deccan Plateau.

The eastward extensions of Peninsular Plateau are locally known as Bundelkhand and Baghelkhand. The Chhota Nagpur Plateau marks the further eastward extension drained by the Damodar river.

The Deccan Plateau, a triangular mass, lies to the south of the river Narmada.

The western and eastern edges of the Deccan Plateau are marked by the Western Ghats and the Eastern Ghats respectively.

The Western Ghats are higher than the Eastern Ghats.

The Malwa Plateau is spread across Rajasthan, Madhya Pradesh and Gujarat and slopes towards the
north.

A distinct feature of the peninsular plateau is the black soil area known as Deccan Trap.

The Indian Desert

The undulating sandy plain covered with sand dunes towards the western margins of the Aravalli Hills is the Indian Desert.

Crescent-shaped dunes called barchans cover large parts of the Indian Desert.

Luni is the only large river that flouts in this region.

The Coastal Plains

The narrow’ coastal strips flank the Peninsular Plateau.

On the west, the coastal strips are divided into Konkan (Mumbai-Goa), Kannada Plain and the Malabar Coast from northern to the southern part.

On the east the coastal strip is divided into Northern Circar and the Coromandel Coast from northern to southern part.

The Islands

The Lakshadweep Islands group in the Arabian Sea is close to Kerala.

The Andaman and Nicobar Islands are the two island groups. Andaman Island consists of 204 small islands. India’s only active volcano, Barren Island is situated here.

CBSE Class 12 Physical Education Notes Chapter 5 Children and Sports is part of Class 12 Physical Education Notes for Quick Revision. Here we have given NCERT Physical Education Class 12 Notes Chapter 5 Children and Sports.

Physical Education Class 12 Notes Chapter 5 Children and Sports

5.1 Motor Development
Motor development only happens when the child is biologically and mentally ready for it. Motor development refers to the development of movement and various motor abilities from birth till death. It is the ability to move around and manipulate his/her environment. There are four stages of motor development in children

  1. Infanthood (0-2 years)
  2. Early childhood (2-6 years)
  3. Middle childhood (7-12 years)
  4. Later childhood (12 years and later)

The first stage is marked by extremely rapid growth and development, as is the second stage. By the age of 2 years, this development has begun to level out somewhat. The final stage does not have any marked new development; rather it is characterised by the mastering and development of the skills achieved in the first two stages. Before the stages of childhood, there is the age of infancy that is from 0-2 years.

Types of Motor Development
There are two types of motor development/skills

  1. Gross Motor Development This development uses the larger muscles of the skeleton or groups of larger muscles to maintain posture and balance for activities such as throwing a ball, walking, running and hopping.
  2. Fine Motor Development This development uses the smaller muscles of the hand, feet and face for more precise activities such as eating, speaking, playing with toys and eventually writing.

Factors that Influence Motor Development
The development and quality of a child’s motor skills are influenced by many factors. These include

  1. Tone It refers to the ongoing contraction and state of the muscle at rest. Tone can be normal, hypotonic or hypertonic.
  2. Strength It refers to the force of a muscle contraction purposefully exerted against resistance to carry out an activity.
  3. Endurance This is the ability to maintain the exertion required for an activity.
  4. Motor Planning It is the complex and often intuitive ability to know how to carry out the steps needed to complete a physical, activity.
  5. Sensory Integration It is the ability to accurately interpret sensory input from the environment and to produce an appropriate motor response.

5.2 Exercise Guidelines at Different Stages of Growth and Development
The motor development in children takes place in various stages of growth. The infanthood or infancy is followed by the childhood, stage that is divided into three stages : the early, middle and later childhood.

Infanthood (0-12 Months)

  • Turns head.
  • Moves arms and legs.
  • Reaches and grasps objects.
  • Rolls back from side to side.
  • Crawls, stands and walks.

Childhood (2-12 Years)
2-5 Years (Early Childhood)

  • Basic locomotor.
  • Ball-handling.
  • Eye-hand coordination.
  • Running, jumping, hopping, skipping grasping.
  • Games with-simple rules.

6-10 Years (Middle Childhood)

  • Fine motor skills.
  • Fine eye-hand coordination.
  • Growth is relatively slow.
  • Cognitive activities.
  • Movement precision.
  • Balancing and coordination.
  • Catching, throwing; kicking.
  • Planned activities games.

11-12 Years (Late Childhood)

  • Motor skills perfected.
  • Onset of puberty.
  • Beginning of sexual maturation.
  • Competition.
  • Planned activities, that involve a .lot of movements.

5.3 Weight Trainin
Weight training refers to the physical exercise which involves lifting weights to improve the” performance of the muscles. Weight training-for children carries with it a variety of advantages

  • It builds muscle strength and strong bones.
  • It reduces excess, body weight.
  • It boosts confidence.
  • It makes a child more competitive.

Disadvantages of weight training are as follows

  • Serious injuries have come from situations with home gym equipment when there was no supervision.
  • Another disadvantage is the risk of non-flexibility. This happens when proper exercise to. increase flexibility is not done along with weight training. If weight training is combined with flexibility exercises then this problem will not occur.

5.4 Concept of Correct Posture
Correct posture is one in which the body is so balanced as to produce least fatigue. It means that correct posture is the position of the body held without any sense of effort. The body weight should be equally distributed over both the legs and feet so as to produce least fatigue. Correct posture may also be defined as that assumed position which enables the body to perform or function effectively.
These are stated below
1. Correct Posture of Standing In standing position, both the heels of the feet should meet each other. The whole body should be erect, knees straight, chin inside, chest forward, belly backward and pressed inside with equal body weight on both feet. In this position, the complete body should be balanced.

2. Correct Posture of Sitting When we sit in a chair, our hips should be in a straight line and erect. Legs should touch the ground and should not be in hanging position. Thighs should be in horizontal position. The backbone should be erect with the upper region of the backbone straight against the back of the chair. While we read, the book should be on the table but the book should not be too away or too near the eyes. The approximate distance between book and eyes should be at least
30 cms. For writing, a table with slight inclination towards the outside is appropriate.

Advantages of Correct Posture
Advantages of correct posture are as follows

  1. Improves Physical Appearance A good posture helps in creating a good impression and improves the physical appearance. This in turn helps in building an impressive personality.
  2. Have more Energy Good posture ensures greater energy as the mind and body work in coordination with each other. More energy means more capacity to work and perform tasks.
  3. Increases Flexibility Good posture ensures proper alignment of the body as well as balanced approach. This increases the flexibility of the body as bones and muscles remain well toned.
  4. Reduces Muscle Tension Good posture does not put excess pressure on a particular muscle. Therefore the muscles remain in their normal position. Neither it brings stiffness to any part of the body so there is no tightening of the muscles.
  5. Increases Confidence An upright and relaxed posture increases strength and power of a person. This helps the individual to sit or stand upright which brings in confidence.

5.5 Causes of Bad Posture
Poor posture is the posture that results from certain muscles tightening up or shortening. There are different factors which can impact on posture. Some common causes for bad posture are given below

  1. Pain or Past Injuries In order to avoid the pain in the body such as back pain or simply to avoid pain from past injuries, people try to overcome the pain by holding the body in a different position. When this posture is continued for a long time, it can become a daily habit. Hence holding yourself differently can be due to some pain or muscle injury in any part of your body.
  2. Low Nutrition Low nutrition and lack of vitamins and calcium in the diet can affect the bones and muscles by not providing adequate strength and flexibility to hold your body in a correct posture.
  3. Hereditary Reasons Having a family history of bent back or flat foot, may cause bad posture. The genes may be responsible for poor posture.
  4. Overweight and Obesity Extra body weight can also be the reason for poor posture. Obese and overweight people tend to collect excess fat around their stomach and hips. This puts strain on the skeletal system as well as muscles thereby resulting in poor posture.
  5. Habit Sometimes, the way you walk or . the way you hold things can be the reason of bad posture. For instance, if you always walk with your head down or slump your shoulders, this can cause your posture to pull out from proper alignment. Sometimes, carrying weight on only one side of the body can contribute to imbalanced or poor posture. This is especially true for children who carry heavy bags to school on one side of their body, as the bones are soft at this age. .
  6. Type of Job People who have desk jobs often push their neck and head forward and hunch their shoulders. All these factors contribute to our inability to keep our spines straight and results in – poor posture.
  7. Lifestyle and Fashion Clothing and shoes especially affect posture. Women who walk in pencil heels are more prone to cause problems to their posture. Besides high heeled shoes, wearing boots, tight fitting clothes, low waist jeans and wide belts can cause bad posture. This changes your centre of gravity, which ultimately causes your posture to suffer.

5.6 Common Postural Deformities
This refers to the deformation in the skeletal structure or where the body parts are not aligned that results in some kind of postural deformities. People having postural deformities cannot perform their work efficiently. Some common postural deformities are Knock Knee, Flat Foot, Round Shoulders, Lordosis, Kyphosis, Bow Legs and Scoliosis.
1. Knock Knee
Knock knee is a postural deformity in which both the knees touch or overlap’each other in the normal standing position. Due to this deformity, an individual usually faces difficulty during walking.

Causes

  • Weakness of muscles and ligaments.
  • Overweight body.
  • Lack of balanced diet.
  • Lack of vitamin D, calcium and phosphorus.

Precautions

  • Balanced diet should be taken.
  • Do not force the babies to walk at early age.

Corrective Measures

  • Horse riding is to be done regularly, as it is one of the best exercise’s for correcting this problem.
  • Keep a pillow between your knees whenever possible.
  • Perform Padmasana and Gomukhasana.
  • Take nutritious meals.

2. Flat Foot
It is a deformity of the feet. In this deformity, there is no arch in the foot and the foot is completely flat. The individual faces problems in standings walking, jumping and running; –

Causes

  • Perform Chakrasana and Dhanurasana for some time.
  • Hold the horizontal bar for some time.

4. Lordosis
It is the inward curvature of the spine or a deformity of spinal curvature. It is an increased forward curve in the lumbar region. It creates problems in standing and walking.

Causes

  • Habitual over-eating.
  • Improper environment.
  • Diseases affecting vertebrae.
  • Improper development of muscles.
  • Lack of exercise.

13. Read the following extract from an article in a magazine and then using your own ideas, write an article for your school magazine on the Delights and Usefulness of Walking.
‘Walking has its own delights. Sadly, in India walking is associated with deprivation and poverty. “If you have a car, why walk ?” asked the professor, starting his Maruti for the few metres from his house to the college building. Pedestrians get second class treatment.’
Answer:

Delights and Usefulness of Walking

Walking is a pleasure. When we are in a vehicle, our attention is fixed on the road. There is no time for the things on either side of the road. A walker can, however, enjoy the sights on either sides. He can walk slowly when there is much beauty around. He can go fast when he wants his walking to be an exercise. However, no young person should walk thinking that it is an exercise. It will kill all the pleasure. Moreover, there are many other exercises that are good for health. Walking should be made a habit for enjoyment. One should feel relaxed and not tired after a good walk. We should walk only when the weather is fine. We should avoid walking when it is hot or misty.

15. Deepika Lai sees the poster below on child abuse. She decides to write to the editor of a local newspaper voicing her concern about the growing crime. Prepare that ’ article considering yourself to be Deepika Lai.
People’S Forum Against Child Abuse
Issues

  • Laws governing child abuse
  • Society’s reaction
  • Family support
  • Victim’s trauma

Answer:

Growing Crime in Society
—Deepika Lai

Almost in all small hotels, dhabas and tea shops one can see small children working. In small scale industries they work in the most unhygienic conditions. The society reacts to such inhuman scenes with indifference. The responsible people pass by such scenes. Even government officials ignore taking any action against the guilty. There is no doubt that family support is behind this child abuse. It is – poverty and lack of employment that is responsible for it. It is hunger that forces the children to work. One can well imagine what the children feel when they are forced to work. Their sweet childhood is snatched from them. Instead of learning the alphabet, they learn to clean the plates. And this goes on without any prick to our conscience.

Drainage Class 9 Notes Social Science Geography Chapter 3

In the previous 3 years’ examinations, significant importance has been given to the following topics from this chapter.

  • Drainage Patterns
  • Various River Basin System
  • Pollution of Rivers.

Drainage’ is a term signifying the river system of an area.

A drainage basin or river basin is an area w’hich is drained by a single river system.

An upland that separates two drainage systems that are next to each other is called a water divide.

On the basis of origin, there are two river systems of India — The Himalayan rivers and the Peninsular rivers.

Himalayan rivers are rainfed and snowfed, so they have w?ater in them throughout the year, i.e., they are perennial and thus navigable.

Himalayan rivers create meanders, oxbow lakes and other depositional features on their course.

Peninsular rivers are seasonal; mostly depending on rainfall and thus non-navigable.

Most of the rivers of peninsular India originate in the Western Ghats and flow’ towards the Bay of Bengal.

The Himalayan Rivers

A river along with its tributaries may be called a river system.

The major Himalayan rivers are the Indus, the Ganga, and the Brahmaputra.

The Indus River System

Rising near Lake Mansarovar in Tibet, the Indus enters India in the Ladakh district of Jammu and Kashmir.

Rivers Satluj, Beas, Ravi, Chenab and Jhelum join Indus near Mithankot, Pakistan and flow southwards to fall into the Arabian Sea, east of Karachi.

With a total length of 2,900 km, the Indus is one of the longest rivers of the world.

The Ganga River System

The headwaters of the Ganga are called ‘Bhagirathi’.

Bhagirathi is fed by the Gangotri Glacier and joined by the Alaknanda at Devprayag.

Ganga meets the tributaries from the Himalayas such as Ghaghara, Gandak, Kosi and the Yamuna.

A major river Yamuna, arising from Yamunotri Glader in the Himalayas, joins Ganga at Allahabad.

Other tributaries — Chambal, Betwa and Son — come from Peninsular uplands to join Ganga.

Ganga is joined by the Brahmaputra and flows through Bangladesh to reach the Bay of Bengal.

The delta formed when the Ganga and the Brahmaputra flow into the Bay of Bengal is known as the Sunderban Delta.

The length of the Ganga is over 2,500 km and it develops large meanders.

The Brahmaputra River System

Originating in Tibet, very close to the sources of Indus and Satluj, Brahmaputra enters India in Arunachal Pradesh and flows to Assam, joined by many tributaries.

The tributaries that join the Brahmaputra are Dibang, Lohit, and Kenula.

The Brahmaputra has a braided channel in its entire length in Assam to form many riverine islands.

Unlike other north Indian rivers, the Brahmaputra is marked by huge deposits of silt on its bed, causing the riverbed to rise.

The Peninsular Rivers

The major rivers of the peninsula—Mahanadi, Godavari, Krishna, and Kaveri—flow eastwards to drain into the Bay of Bengal.

The Thai and Narmada are the only rivers which flow west to make estuaries and drain into the Arabian Sea.

The drainage basins of the peninsular rivers are comparatively small in size.

The Godavari Basin

The Godavari begins in Nasik district of Maharashtra. It is the largest peninsular river.

Its large basin covers most parts of Maharashtra, Madhya Pradesh, Orissa and Andhra Pradesh.

The tributaries which join the Godavari include Purna, Wardha, Pranhita, Manjra, Wainganga and Penganga.

Because of its length and the area, it covers, the Godavari is also known as the Dakshin Ganga.

The Godavari drains into the Bay of Bengal.

The Mahanadi Basin

The Mahanadi, a 860 km long river, rises in Chhattisgarh to flow through Orissa to reach the Bay of Bengal.

Principal tributaries of Mahanadi river are Sheonath, Jonk, Hasdeo, Mand, lb, Ong and Tel.

Mahanadi river basin is shared by Maharashtra, Orissa, Jharkhand and Chhattisgarh.

Is is one of the major east flowing peninsular rivers draining into Bay of Bengal.

The Krishna Basin

The 1,400 km long Krishna river rises from a spring in the Mahadev range near Mahabaleshwar and falls into the Bay of Bengal.

The tributaries of Krishna include Bhima, Musi, Ghatprabha, Koyana and Tungabhadra. The Krishna basin is shared by Maharashtra, Karnataka and Andhra Pradesh.

The Narmada Basin

Rising in the Amarkantak Plateau of Maikala Range, Narmada flows to create a gorge in marble rocks of Madhya Pradesh.

Narmada flows towards the west in a rift valley formed due to faulting. •

Narmada river has 41 tributaries. The important ones are: Barna, Ganjal, Chhota Tawa, Hiran, Janatara, Kolar, Orsang, Sher.

The Tapi Basin

Originating in Betul, Madhya Pradesh, the Tapi flows through a basin that covers Madhya Pradesh, Gujarat and Maharashtra.

The main west flowing rivers are Sabarmati, Mahi, Bharatpuzha and Periyar.

The entire Tapi basin can be divided into three sub-basins: upper, middle and lower and into two well- defined physical regions, viz, the hilly regions and the plains or Tapi Basin.

The Kaveri Basin

Originating in the Brahmagiri range of the Western Ghats, the Kaveri reaches the Bay of Bengal at Kaveripatnam, sharing its basin with Karnataka, Tamil Nadu, Kerala and Puducherry or Pondicherry.

The main soil types found in the basin are red and yellow soils.

Lakes

Most lakes are permanent while others contain water only during the rainy season.

Some lakes are the result of the glacial action and ice sheets and some may have been formed by wind, river action and human activities.

A river meandering across a floodplain forms cut-offs that later develop into oxbow lakes.

Glacial lakes are formed when glaciers dig out a basin which is later filled with snowmelt.

Some lakes like Wular Lake in Jammu and Kashmir result from tectonic activity.

Apart from natural lakes, the damming of the rivers for the generation of hydel power has also led to the formation of lakes.

Lakes help to regulate river water flow, prevent flooding, aid to develop hydel power, moderate climate, maintain aquatic ecosystem, enhance natural beauty, develop tourism and provide recreation.

Role of Rivers in the Economy

Rivers are a natural source of water. It forms the main backbone for agriculture.

Settlements on the river banks have developed into cities.

Rivers are used for irrigation, navigation, hydropower generation, all vital for India, and agricultural economy.

River Pollution

Quality of river water is affected by the growing domestic, municipal, iftdustrial and agricultural demand.

A heavy load of untreated sewage and industrial effluents are emptied into the river affecting the river’s self-cleansing property.

Concern over rising pollution in our rivers led to the launching of various action plans to clean the rivers like Narmada Bachao Movement.

Dear Anupam

I regret to inform you that my house has been burgled while I was away on a holiday. The burglar opened the lock of the main gate with my own key and decamped with the valuables.

I usually return home from office at 6 pm. When I did not turn up for two days, the burglar must have concluded that I would not come on that fateful day.

I usually keep my keys in a chink in the inside of the outer wall. I should have taken the keys with me. Or I must have informed my neighbour facing my house of my holidaying. The burglar might not have entered the house had I been a bit careful.

Yours affectionately
Praveen

He writes an article for his city newspaper expressing his alarm and painting the present position cautioning people against environmental pollution. Write that article considering yourself to be Gauri.
CBSE Class 8 English Composition Based on Visual Input 1
Answer:

Pollution
Or
The Traffic on the Road

Our cities are changing very fast. My father tells me there were no traffic jams in our city ten years before. Then no body found it difficult to cross the road. Today, the roads are better and wider but crossing them is always dangerous. The traffic jams have become common. There are few trees. In the evening the smoke envelops the city. It is not easy to breathe in the polluted air. It is all due to the vehicles on the road. There are more cars than the city roads can accommodate. As a result breathing diseases such as asthma have become very common. Something must be done to lessen the number of vehicles on the road.

Answer:
The Editor
Jan Jagriti
Surat
3 March, 2017
Sir
Through your newspaper. I wish to draw the attention of the authorities towards my city. The city seems to have become a dustbin. The sweepers sweep the roads but leave the garbage on the sides. This garbage lies there for weeks. The pigs and such other animals can be seen feasting on it. Stray dogs are a worse nuisance. They do not bark but bite. Many people have suffered because of them. There are open drains in many parts of the city. These drains are almost always choked. So the dirty water flows on the road making the air foul-smelling.

I urge the concerned authorities to take immediate steps to clean all garbage. The drains must at once be cleaned. In short, the city must be made worth living.
Yours faithfully

CBSE Class 12 Physical Education Notes Chapter 6 Women and Sports is part of Class 12 Physical Education Notes for Quick Revision. Here we have given NCERT Physical Education Class 12 Notes Chapter 6 Women and Sports.

Physical Education Class 12 Notes Chapter 6 Women and Sports

6.1 Sports Participation of Women in India
The participation of women in sports in India is very small. Gender inequality is strongly evident in every field of life including sports. The problem is more socio-psychological than anything else. The Government of India instituted the National Sports Festival for Women with the objective to promote women’s sports. However, this programme could not bring any noticeable improvement in women’s participation in sports.
Surveys have shown that women don’t participate in sports due to

  1. Time Constraints Women find less time for sports due to their domestic duties.
  2. Social Constraints The attitude of society towards participation of women in sports is negative.
  3. Lack of Sports Infrastructure Specialised coaching centres, training programmes, equipment that are suitable for women athletes are not present adequately.
  4. Absence of Skill There are very few female coaches available to develop the skills of women. Sociological constraints limit the success of male coaches with female athletes.
  5. Concerns for Personal Safety Women are more afraid to venture in a ‘male’ field (perceived) as they are concerned more about safety from harassment or exploitation.

Methods to Increase Women’s Participation in Sports
There are various ways in which women’s participation can be increased

Coaching Programmes
Women should be encouraged and provided with the opportunity to undertake leadership positions within organisations. They should be provided with good technical instruction. They must be given positive, encouraging, and instructive feedback. They should have a strong voice in programmes and all concerned should maintain a flexible approach to participation to ensure their needs are heard and met.

Safety
Exercising in groups can make physical activity safer for women and girls. Community sports facilities should be provided with separate location for women.

Facilities
Changing facilities must he provided that take, into account women’s and girl’s hygiene needs. Adequate ‘ provision for childcare should be made so that women without any hesitation can bring their children to the participation and training venues. We must ensure that all areas are easily accessible to girls and their .. parents. . ;

Price/Affordability
Participation fee in sports should be reduced or abolished for women. Concessions for travelling and boarding should be provided to women.

6.2 Special Considerations Associated with Physiology
Special care should be taken by sportswomen because of the problems associated with their physiology. Problems faced by women during their life are
Menarche
Menarche is a girl’s first menstrual period. It can happen as early as age 9 or upto age 15. During this time, girls feel tense and emotional. So special attention should be given to them at this time. As a sportsperson, a young woman has to take special care of herself at that time.

Menstrual Dysfunction
Due to participation of women in physical fitness and competitive endurance sports, the incidence of menstrual dysfunction has increased. Long distance . running and other sports may lead to alterations in androgen, estrogen and progesterone hormones, which in some women may directly or indirectly result in amenorrhea (absence of menstrual periods) or infertility.

6.3 Female Athlete Triad
The ‘female athlete triad’ is a syndrome of three related conditions generally seen in teenage or adult female athletes who aren’t meeting their energy requirements, which ultimately leaves them undernourished. This also affects their performance severely.
The three components of the female athlete triad include

  1. Osteoporosis Itis a condition in which bones become weak and brittle. It occurs when the body loses too much bone, makes too little bones or both.
  2. Amenorrhiea It isthe absence of menstruation periods’that can-happen for many reasons. Main causes are
    genetic abnormalities, excessive exercise and extreme physical or psychological stress.
  3. Eating Disorders It refers to either eating in excessive amounts or eating in very little amounts. This disorder is related to mental illness and affects a – person’s physical and. mental health.
    A female athlete can have one, two, or all three parts of the triad.

6.4 Psychological Aspects of Women Athletes
Psychological aspects of Women athletes are discussed below

  1. Stress All women athletes undergo various degrees of stress-due to increased competition and. male domination. But women are able-to handle stress in a better way as they are more open and have a large social circle.
  2. Aggression Women may experience aggression that may reduce then- performance in sports. But they are able to manqge the aggression and also are less aggressive in nature.
  3. Sensitive Women are more sensitive to the reaction of the people towards them. Therefore positive reinforcements by parents, coach, friends can enhance their performance.
  4. Eager to Learn Women are more eager to learn the new skills and techniques. Therefore coaching is easier in case of women athletes.
  5. Coping Women are able to handle and manage their emotional and interpersonal problems in a more efficient way. This helps women athletes to make strategies for better performance.

6.5 Sociological Aspects of Sports Participation
The sociological aspects that prevent women athletes in sports participation are as follows

  1. Social Stigma The social outlook is that girls are feeble, weak as compared to men and therefore they should not participate in sports.
  2. Safety Issues Girls have to face certain safety issues such as late night training, going to and coming from sports venues, coaching centres etc. Due to this, they find it difficult to pursue sports.
  3. Lack of Proper Facilities Women have to face lack of specific facilities such as separate changing rooms, rest rooms etc. This leaves very few opportunities for women.
  4. Lack of Role Models In the absence of women’s greater participation in sports, there are no role models. Due to this, girls do not get encouragement from parents or coaches.
  5. Less Media Coverage Women sports tournaments do not get wide coverage as men’s sports. Electronic and print media do not give proper attention on women tournaments. Therefore women do not get encouragement to participate in sports.

  • Welfare programmes specially meant for OBCs should be financed by the Government of India.

Question 3.
Describe the era of multi-party system in India after 1989. (Delhi 2015)
Answer:
Elections in 1989 led to the defeat of the Congress party but did not result in a majority for any other party. Though Congress was the largest party in the Lok Sabha, it did not have a clear majority.

The defeat of the Congress party marked the end of Congress dominance over the Indian party system.

Way back in the late sixties, the dominance of the Congress party was challenged; but the Congress under the leadership of Indira Gandhi managed to re-establish its predominant position in politics.

The nineties saw yet another challenge to the predominant position of the Congress. It did not, however, mean the emergence of any other single party to fill in its place. Thus, began an era of a multi-party system.

To be sure, a large number of political parties always contested elections in our country. Our Parliament always had representatives from several political parties. What happened after 1989 was the emergence of several parties in such a way that one or two parties did not get most of the votes of seats.

This also meant that no single party secured a clear majority of seats in any Lok Sabha election held since 1989. This development initiated an era of coalition governments at the Centre, in which regional parties played a crucial role in forming ruling alliances.

The nineties also saw the emergence of powerful parties and movements that represented the Dalit and backward castes (Other Backward Classes or OBC). Many of these parties represented powerful regional assertion as well.

Question 4.
Describe any four major developments in Indian politics since 1989. (Delhi 2015)
OR
Describe any two developments witnessed by India after 1990. (All India 2011)
OR
Describe briefly any four main developments, witnessed by the country from 1989 to 1992. (All India 2008)
Answer:
Towards the end of 1980s, country saw five major development which are as follows (any four) :
1. End of Congress system mean dominance of Congress for two decades. But the most important event was the defeat of Congress party in the 1989’s elections. The party had won only 197 seats, which was very low in comparision to 1984 elections where party won 415 seats.

The Congress boosted up its performance and finally it came back to power in 1991, after Rajiv Gandhi’s assassination. But the elections of 1989 marked the end of what political scientists have called the ‘Congress system’, congress remained as major party but it lost its dominance as it enjoyed earlier in the party system.

2. Mandal Issue The Mandal issue started with the National Front government’s decision to implement the recommendations of Mandal Commission in 1990. The recommendation was that 27 per cent of job in the Central Government should be reserved for other backward classes’s candidates only.

Thus, it brought widespread dismay and anger. This conflict between supporters and opponents of OBC reservation was popularly called ‘Mandal issue’. It played a crucial role in shaping politics since 1989.

3. New Economic Reforms The new Ans economic reforms were announced as the structural adjustment programme. These reforms were initiated by Rajiv Gandhi, but these were more visible in Narsimha Rao’s Government in the year 1991. These reforms faced many criticism, but the upcoming governments have continued to follow these.

4. Assassination of Rajiv Gandhi There was a change in leadership due to assassination of Rajiv Gandhi in May 1991. He was assassinated during his election campaign in Tamil Nadu by a Sri Lankan Tamil linked to the LTTE. The elections of 1991 witnessed Congress party emerging as the single largest party.Though death of Rajiv Gandhi led to the appointment of Narsimha Rao as the Prime Minister.

5. Ayodhya Issue The Ayodhya issue was started with the demolition of Babri Masjid in December, 1992. This, incident led to violence and many questions were raised about the nature of Indian nationalism and secularsm. This issue exemplified and provoked various changes in the politics of the country and guided the rise of the BJP and the politics of Hindutva.

Question 5.
Rewrite the names of any of the following Prime Ministers in the chronological order keeping in mind the period of their Prime Ministership. (All India 2010)
(i) Chandrashekhar
(ii) Narasimha Rao
(iii) HD Deve Gowda

(v) VP Singh
Answer:
Chronological order for the period of their Prime Ministership
(i) VP Singh
(ii) Chandrashekhar
(iii) Narasimha Rao
(iv) HD Deva Gowda
(v) IK Gujral

Question 6.
‘In the new era of coalition politics political parties are not aligning on the basis of ideology’. Explain. (Delhi 2009)
Answer:
Three features of coalition government has been given in which we have to understand the not aligning and re-aligning on the basis of ideologies. These are :

  1. Unstable government The coalition government has its own interest and they fight for their own self interest. This leads to the breakup of not only of various fronts, but of governments as well.
  2. Political opportunism Government formed on the basis of coalition becomes selfish, as opportunist, power hungry and unscrupulous politicians focus on the self-interest only.
  3. Lack of polarisation The coalition governments are formed not on the basis of polarisation of political forces, but for the sake of capturing power and vested interest. There have been no sincere urge even among the parties of same ideology for political polarisation.

Question 7.
What was Godhra episode? What were its after-effects? (Delhi 2009)
OR
Why did the anti-Muslim riots take place in 2002 in Gujarat ? What were the outcomes of these riots? (All India (C) 2008)
Answer:
In February-March 2002 large scale violence took place against Muslims in Gujarat because :

  1. At Godhra station a bogey of Sabarmati Express train was set on fire which was full of Karsevaks. They were returning from Ayodhya.
  2. Suspecting the hands of Muslims in setting fire to the bogey large-scale violence against Muslims began in Gujarat from the next day.

The outcomes of these riots were :

  • This violence continued for almost a whole month. Nearly 1100 persons, mostly Muslims were killed.
  • The National Human Rights Commission criticised the Gujarat Government’s role in failing to control this communal violence, providing relief to the victims and prosecute the perpetrators of this violence.
  • The Election Commission of India ordered are assembly elections to be postponed.

6 Marks Questions

Question 1.
Describe any three points of consensus that emerged among most political parties in India in spite of severe competition and conflicts. (All India 2015)
OR
Highlight any three issues on which a broad agreement has emerged among most of the political parties in India. (All India 2013)
OR
In the midst of severe competition and many conflicts in 1989, a consensus appeared to have emerged among most parties. Explain any three points of consensus. (All India 2012)
OR
Explain any three elements of consensus which have emerged among most political parties after the Lok Sabha elections of 2004. (All India 2011)
OR
‘Inspite of serious differences between major national political parties, emergence of new consensus is being viewed with interest’. In the light of this statement describe any three consensus. (HOTS: Delhi 2010)
Answer:
Inspite of serious differences between major national political parties emergence of new consensus is being viewed with interest in the light of statement as following :
1. Acceptance of political and social claims of the backward castes
Most of the political parties accepted the adequate representation. As a result, all political parties supported reservation for OBCs in education and employment. Political parties even want to ensure that OBCs get their due share of power.

2. Role of state-level parties
The role of state-level parties in governance of the country has been recognised. The gap between centre and state level parties decreased. State level parties are sharing power at central level and have become crucial for the survival of country’s politics in the last two decades.

3. Focus on pragmatic consideration
Coalition politics has shifted political alignments from ideological differences to power-sharing agreements. Governance is based on pragmatic consideration and political alliances take no rigid ideological positions. Thus, the alliance with BJP was formed called NDA in spite of BJP Hindutva. The NDA government lasted for its full term in office.

Question 2.
Which three major developments took place in Indian politics during the last decade of the 20th century? Describe. (All India 2015)
OR
“Towards the end of the 1980s, five major changes took place in Indian political system.” In light of this statement, examine any three changes. (Delhi 2011)
Answer:
For major development in Indian politics towards the end of 1980s, country saw five major development which are as follows (any four) :
1. End of Congress system mean dominance of Congress for two decades. But the most important event was the defeat of Congress party in the 1989’s elections. The party had won only 197 seats, which was very low in comparision to 1984 elections where party won 415 seats.

The Congress boosted up its performance and finally it came back to power in 1991, after Rajiv Gandhi’s assassination. But the elections of 1989 marked the end of what political scientists have called the ‘Congress system’, congress remained as major party but it lost its dominance as it enjoyed earlier in the party system.

2. Mandal Issue The Mandal issue started with the National Front government’s decision to implement the recommendations of Mandal Commission in 1990. The recommendation was that 27 per cent of job in the Central Government should be reserved for other backward classes’s candidates only.

Thus, it brought widespread dismay and anger. This conflict between supporters and opponents of OBC reservation was popularly called ‘Mandal issue’. It played a crucial role in shaping politics since 1989.

This, incident led to violence and many questions were raised about the nature of Indian nationalism and secularsm. This issue exemplified and provoked various changes in the politics of the country and guided the rise of the BJP and the politics of Hindutva.

Question 3.
Coalition government is a bane or boon for democracy in India’. Explain any three arguments in support of your answer. (Delhi 2011)
Answer:
Coalition government is a boon because :

  1. Participation of regional parties at national level State level parties played a crucial role in the country politics for last twenty years. Therefore the differences between state-level parties and central parties is decreasing day-by-day.
  2. Spirit of adaptation Coalition politics has shifted the focus of political parties from ideological distinctions to power sharing accommodation. We can see in the government of NDA that most of the parties did not agree with the ideology of Hindutva of BJP. However, they allied with BJP to form a government for a full term completion.
  3. Inclined towards one consensus Various radical parties opposed the new economic policies, but some parties came to support new economic policies because they believed that these policies would lead the country towards prosperity and raise its status all over the world. Coalition government is a bane for democracy in India because of three reasons:
    • Unstable government The coalition government has its own interest and they fight for their own self-interest. This leads to the breakup not only of various fronts but of governments as well.
    • Political opportunism Government which is formed on the basis of coalition becomes selfish as opportunist power hungry and unscrupulous politicians emphasise on their self-interest only.
    • Lack of polarisation The coalition governments are formed not on the basis of polarisation of political forces, but for the sake of capturing power and vested interest. There have been no sincere urge even among the parties of same ideology for political polarisation.

Question 4.
From 1989 to 2004, there have been nine coalition governments in India. Analyse the rise and fall of any two such coalition governments. (Delhi 2010)
OR
“The era of coalition in India started in 1989, which has come to stay in a big way.” Do you agree? Substantiate your answer by any three arguments. (HOTS; All India 2010)
Answer:
The era 1990s witnessed the emergence of strong political parties, regional parties through several issues viz OBC, Dalit etc. These parties formed government through alliances. Such alliance were United Front, National Front in 1996 and 1989 respectively.

Coalition from 1989 to 2004
Some parties had Congress support and formed alliance in 1996 called United Front. In 1989, BJP and Left supported National front.

In 1989, BJP and Left wanted to keep the Congress out of power, hence, both supported National Front and later in 1996, Congress wanted to keepout BJP from the power. Therefore, it supported United front and Left supported Congress in 1996. The alliance government did not succeed for long because BJP continued to strengthen its position in the elections of 1991 and 1996. The BJP was the single largest party in 1996 parliamentary election.

In 1996, BJP was invited to form the government, but most of the political parties opposed its policies consequently it could not secure a majority in the Lok Sabha.

Lok Sabha Elections, 2004
In 2004 elections, the Congress party came to power with the new alliance known as United Progressive Alliance.This was a coalition in a big way. NDA was defeated and installation of another coalition led by DR. Manmohan Singh occurred. The UPA received support from DMK, PMK, AIADMK, RJD, NCP, TRS and left from Andhra Pradesh etc.

The 2004 elections also saw the partial revival of Congress party as it increased its seats compared to 1996 elections. However, there was a little bit difference between the votes polled by the Congress and its allies and the BJP and its allies in 2004 elections. Thus, the party system has taken another form suddenly from what it was till the seventies.

After the 1990s, the political process has been changed and it led to emergence of broadly four groups of parties:

  • The Congress supporting parties that made coalition with Congress.
  • The BJP allying parties
  • Left front parties
  • Some other parties which were not part of the above three

Question 5.
“The end of Eighties of the 20th century witnessed developments which made a long lasting impact on Indian parities”. Assess any three such developments, (HOTS; Delhi 2010)
Answer:
The end of eighties of the 20th century witnessed major development which have lasting impact on Indian politics, are as follows:
(i) End of Congress system
mean dominance of Congress for two decades. But the most important event was the defeat of Congress party in the 1989’s elections. The party had won only 197 seats, which was very low in comparison to 1984 elections where party won 415 seats.

Congress boosted up its performance and finally it came back to power in 1991, after Rajiv Gandhi’s assassination. But the elections of 1989 marked the end of what political scientists have called the ‘Congress system’. Congress remained as major party but it lost its dominance as it enjoyed earlier in the party system.

(ii) Mandal issue
The Mandal issue started with the National Front Government’s decision to implement the recommendations of Mandal Commission in 1990. The recommendation was that 27 per cent of job in the Central Government should be reserved for other backward classes’s candidates only. Thus, it brought widespread agitation and anger. This conflict between supporters and opponents of OBC reservation was popularly called ‘Mandal issue’. It played a crucial role in shaping politics since 1989.

(iii) New economic reforms
The new economic reforms were announced as the structural adjustment programme. These reforms were initiated by Rajiv Gandhi, but these were more visible in Narismha Rao’s Government in the year 1991. These reforms faced many criticism, but the upcoming governments have continued to follow these reforms.

Question 6.
Describe the emergence of the coalition government in India. (All India 2009)
OR
“After the election in 1989, an era of coalition started in which political parties are not aligning or re-aligning on the basis of ideologies”. Explain. (HOTS; All India 2008)
Answer:
Undoubtly, in the new era of coalition politics, political parties are not aligning or re-aligning on the basis of ideology. The main basis of their aligning with one or the other party is to safeguard their own interest and to frustrate their opponents.

The best example was of Dr Manmohan Singh’s government where the leftists supported the UPA but in state both are opponents. The main interest was to keep out BJP from government. Same condition occurred in Bihar, when BJP and Janata Dal formed government to keep out RJD.

At the centre, UPA and NDA generally do these things and hence, it could be said that political parties are not aligning or realigning on the basis of ideology.
For features of coalition government on the basis of ideologies

Three features of coalition government has been given in which we have to understand the not aligning and re-aligning on the basis of ideologies. These are :

  1. Unstable government The coalition government has its own interest and they fight for their own self interest. This leads to the breakup of not only of various fronts, but of governments as well.
  2. Political opportunism Government formed on the basis of coalition becomes selfish, as opportunist, power hungry and unscrupulous politicians focus on the self interest only.
  3. Lack of polarisation The coalition governments are formed not on the basis of polarisation of political forces, but for the sake of capturing power and vested interest. There have been no sincere urge even among the parties of same ideology for political polarisation.

Question 7.
A two-party system is considered as the best form for a democratic system. India, on the other hand, has a multi-party system. Assess the advantages of the multi-party system in India. (All India to 2008)
Answer:
Two party systems is required for successful democracy. However, the multi-party system have the following advantages:

  1. No place for dictatorship Even if a party enjoys full majority, it can not function as dictator. The multi-party system provided a democratic government. Hence, if the largest party try do so then other parties will withdraw their support.
  2. Multiple choice of voters Since 1989 elections, voters have choices about whom they want to cast their votes. This is another advantage of multi-party system.
  3. True reflection of public opinion Parliament is the reflection of people. In case of multi-party systems. Parliament becomes a true reflector of people because diversity of culture, language are noticeable in Parliament.
  4. Possibility of stable government There is government majority in Parliament and Council of Ministers work according to the majority. This restricts Parliament not to pass no-confidence motion. Hence, mulit-party system is comparatively stable.
  5. Passing of bills Bills favouring people are passed by the Parliament and it is a coalition government which always asks its member parties to do so.
  6. Check the division of the two camps The two-party system leads to two camps. But the multi-party system checked the two hostile camps. It is rather a cementing force between groups of divergent loyalties.

Question 8.
“The regional parties have started playing an important role in the Indian politics”. Comment. (HOTS: Delhi (C) 2008)
Answer:
India as democracy has the multi-party system which means there are several political parties competing for power. Apart from the primary parties, each state has their own local political parties that rule and compete in their region.

Regional parties play following roles in Indian politics :

  1. In absence of clear majority, the largest party has to join hands with a regional party in order to form government. This is where the importance of the regional parties comes into play.
  2. Most of the regional parties have agenda furthering certain culture dominant within that state.
  3. The regional parties for their benefits divide the people of different states on the line of language, culture, traditions etc.
  4. Sometimes serious issues like India’s foreign policy’ are influenced and compromised by regional parties. This affects India’s credibility in international politics.
  5. They also work as a pressure groups in Indian politics.
  6. Sometimes regional parties influence the central government to divert more annual budget funds to their states at the expense of other states.

CBSE Class 7 Science Notes Chapter 4 Heat

Heat is a form of energy which makes the substance hot. In winter, it is our common experience that we feel cold inside the house and if we come out in front of sun rays, then we feel warm. Now, if we know that how do we feel this sensation of warm or cold? Then, what will be our answer? Think. In this chapter, we will try to find out the answer to such kind of question.

Hot and Cold
In our daily routine, we come across a number of objects, out of which some are hot while other objects are cold, e.g. when a frying pan kept on a burning gas stove becomes hot but the handle of the pan is cold. Even among the hot objects, some objects may be hotter than the other. In the same manner, among the cold objects, some objects may be colder than the other. So, if I ask you how you decide the relative hotness or coldness of objects, then your answer will be’by simply touching the objects’. But our sense of touch is not enough in telling us whether an object is really hot or cold so, this can be understood by performing a simple activity.

Temperature and Thermometer
The degree of hotness or coldness of the object is known as the temperature of an object. The temperature of an object is an only property that indicates which object is hot and which one is cold. A high temperature of a body indicates that it is very hot whereas a low temperature of the object indicates that it is quite cold, e.g. the temperature of boiling water is quite high, so boiling water appears to be very hot. On the other side, the temperature of melting ice is quite low. So, ice appears to be very cold on touch.

It is measured by using an instrument called thermometer, which has a scale marked on it which is used to read the temperature, e.g. the scale in laboratory thermometer is marked along the length of thermometer’s tube between 0° mark and 100° mark into 100 equal divisions. So, each division is called a degree. The temperature of an object should always be stated with its unit. So, the most common unit for measuring temperature is degree Celsius (°C).

Both the clinical thermometer and laboratory thermometer are mercury thermometers. So, when a particular amount of heat is supplied to the thermometer bulb consisting of mercury (by the hot body whose temperature is to be measured), then the mercury expands and get rises in the glass tube of the thermometer. This fact is used in measuring the temperature.

Clinical Thermometer
It is the thermometer which is used for measuring the temperature of the human body. In case of fever, it is used by a doctor (or at home) to measure the temperature of the patient. This thermometer consists of a long glass tube having a thin and uniform bore. There is a glass bulb at one end of the glass tube which consists of mercury as shown in the figure given below:

Features of a Clinical Thermometer
There is a very short range of temperature of a clinical thermometer, i.e. from 35°C to 42°C. The short range of a clinical thermometer is because of the fact that the temperature of human body normally does not go below 35°C or above 42°C.
Heat Class 7 Notes Science Chapter 4 1
Just above the bulb containing mercury, a clinical thermometer has a kink in its glass tube which is to prevent the back flow of mercury into the thermometer bulb when the thermometer bulb is removed from the mouth of a patient. This kink prevents the mercury level in the thermometer tube from falling on its own. Due to this, we can read the correct body temperature of the patient even after removing the thermometer bulb from his mouth.

Note: After noting the body temperature, the level of mercury can be brought down by giving jerk to the thermometer tube.
As mercury is very toxic and is difficult to dispose off, so thermometer must be handled carefully. Clinical thermometer should not be used to measure the temperature of objects other than the human body. It should not be kept in the sun or near a flame, otherwise, it may break. Nowadays, digital thermometers are used which do not use mercury.

Reading a Clinical Thermometer
There are following steps to read the temperature on a thermometer.
Step I: Firstly, wash the thermometer with an antiseptic solution and if in case, the antiseptic solution is not available, then wash it with clean water.
Step II: Gently, hold the thermometer tube in your hand and give it a jerk in such a way that the mercury thread in the thermometer tube falls below the reading of 35°C.
Step III: Now, put the bulb of the thermometer under the tongue of the patient for about one minute. Then take out the thermometer from the patient’s mouth.
Step IV: In order to read the temperature, hold the thermometer horizontally in your hand and rotate it slowly. When we see a magnified image of the mercury thread in its tube, then a position will come. Now, read the temperature on thermometer tube in level with the top of the mercury thread.

Precautions while Reading the Thermometer
A clinical thermometer should not be used for any object other than the human body. There are some following precautions which are to be observed while reading a clinical thermometer.

  • Wash the clinical thermometer before and after using preferably with an antiseptic solution.
  • Be ensure that the mercury level before using the clinical thermometer should be below 35°C.
  • The clinical thermometer should be read by keeping the level of mercury along the line of sight.
  • While reading the clinical thermometer, it should never be held by the bulb.
  • The clinical thermometer should be carefully handled.

Laboratory Thermometer
A device which is used for measuring the temperature in a science laboratory is called a laboratory thermometer.
This thermometer is made up of a long glass tube having a thin bore. The graduation marked on the tube of a laboratory thermometer can measure the temperature from -10°C to 110°C, this is known as the range of a laboratory thermometer. Also, determine how much a small division on this thermometer reads (this is also known as least count of the thermometer), it is due to the fact that this information is required to read the thermometer correctly.
Heat Class 7 Notes Science Chapter 4 2
These are the special thermometers which automatically record the maximum and minimum temperature of the day. The maximum S and minimum temperature of the last day reported in weather reports in TV and newspapers are measured by the maximum-minimum thermometers.

Reading a Laboratory Thermometer
There are following steps to read the temperature on a thermometer.
Step I: First of all, take some hot water in a beaker.
Step II: Now, try to hold the laboratory thermometer from its glass tube and immerse the bulb of the thermometer in hot water taken in the beaker. Notice that the bulb of the thermometer should not touch the sides or the bottom of the beaker as shown in the figure.
Step III: Here, we will observe the shining thread of mercury moving up in the thermometer tube. After some time, the mercury will stop rising and stand at one place.
Now, read the temperature on the thermometer tube which corresponds to the top of the mercury thread. This will give us the temperature of hot water taken in the beaker.
Heat Class 7 Notes Science Chapter 4 3
Note: To measure the human body temperature a laboratory thermometer cannot be used because as soon as we tahe out the bulb of the laboratory thermometer from the mouth of a patient, the mercury level wilt starts falling quickly (due to cooling of its bulb by air). So, this will provide a wrong value of the body temperature.

Precautions in Using a Laboratory Thermometer

  • While -measuring temperature, the laboratory thermometer should be held vertically.
  • The thermometer bulb should be surrounded from all sides by the substance whose temperature is to be measured.
  • The thermometer reading should be taken while its bulb is still in touch with the substance whose temperature is being measured and by keeping the mercury level along the line of sight.
  • The thermometer should not be held by the bulb.
  • The thermometer should be carefully handled.
  • We should note down the temperature reading by keeping the thermometer bulb immersed in hot water because if the thermometer bulb is taken out of hot water, then its mercury thread will start falling and this will give a wrong reading for the temperature of hot water.

Digital Thermometer
There are most of the common thermometers like mercury thermometers which use a liquid metal called mercury for their working. Mercury is a toxic substance (a poisonous substance) and thus it is very difficult to dispose of safely, if a thermometer breaks. So, there is a lot of concern over the use of mercury in thermometers. Also, during these days, digital thermometers are available which do not use mercury.

Transfer of Heat
Heat flows from a hot object to a cold object or heat flows from an object at the higher temperature to another object which is at a lower temperature. This flow of heat is known as the transfer of heat, e.g. if you dip a steel spoon into a cup of hot tea, then we will find that the temperature of spoon rises and it becomes hot. In this case, some of the heat contained in hot tea has been transferred to spoon which is placed inside it.

When the two objects attain the same temperature, then the flow of heat stops. This means that no heat will be transferred from one object to another if the temperature of the two objects is the same.
There are three ways through which heat can be transferred from a hot object to a cold object.

  • By conduction (in solid, heat is transferred by conduction)
  • By convention (in liquid and gases, heat is transferred by convection)
  • By radiation (in free space or vacuum, heat is transferred by radiation)
    Let us discuss all the three ways of heat transfer.

1. Conduction
The mode of transfer of heat from hotter part of a material to its colder part or from a hot material to a cold material in contact with it, without the movement of material as a whole, is known as conduction. In all the solids, heat is transferred by the process of conduction.

Conductor and Insulator of Heat
Materials which allow heat to be conducted through them easily are conductors of heat. Those metals such as iron, copper, silver, aluminium, etc., are good conductors of heat.

Bad conductors of heat are those materials which do not allow heat to be conducted through them easily. These materials are also known as insulators of heat. Wood, plastic and glass are insulators of heat.

Uses of Good and Bad Conductors of Heat
During the winter season, we generally wear woollen clothes. If we compare them with cotton clothes, then we will find that the wool fibres have much more space between them. These get filled with air which is a bad conductor of heat. Hence, being an insulator, both wool and air together prevent the heat from our bodies from escaping out.

Also, jute and sawdust are bad conductors of heat. We cover the ice with a jute cloth of sawdust to prevent it from gaining heat from the surroundings and melting.

The double walls of the refrigerators having space inside which is filled with an insulating material, prevent the heat of the surroundings from reaching the inside of the refrigerator.

The two thinner blankets (one on top of the other) during the winter season are very much effective because the air layer trapped between the thinner blankets creates insulation and provides the protection from cold.

Sometimes, there are two things which are at the same temperature. It seems like they are at different temperatures, one being cold and the other being warm. This happens because some things are a good conductor of heat while others are poor conductors of heat.

e.g. during winter season, a metal object kept in a room feels very cold to touch but a wooden object in the same room feels warmer to touch. Metal object is a good conductor of heat. So, when we touch the metal object, it conducts away heat from our hand quickly. And by losing heat, our hand feels cold. On the other side, the wooden object (being a poor conductor of heat) does not allow the heat of our hand to escape and hence feels warmer to touch.
The water (or most liquids) and air (or gases) are bad conductors of heat.

2. Convection
The mode of transfer of heat from the hotter part of a fluid (liquid or gas) to its colder parts by the movement of the liquid (or gas) itself is known as convection. The transfer of heat by convection can take place only in liquids and gases. It is due to the reason that the particles in liquids and gases can move about freely.

So, the transfer of heat by convection cannot take place in solids because the particles in the solids are fixed at a place and cannot move about freely. It is also not occurred in empty space or vacuum because there are no particles of any kind in empty space which can move and transfer heat.

Convection in Water
Water is a poor conductor of heat. So, due to this reason, it cannot transfer heat by conduction but it transfers heat by the process of convection.

Convection in Air
Air is a very poor conductor of heat, Air transfers heat from its hotter parts to the colder parts by the process of convection.

Sea and Land Breezes
The blowing of sea breeze and land breeze in coastal areas is generally occurred due to the convection of heat in air.

In coastal areas during the day time, the breeze generally flows from the sea towards the land and during the night time, blows from the land towards the sea. Sea and land breezes are actually convection of heat.

During the day, the land heats up more than water. Due to this, the air over the land becomes hotter and lighter and rises up. So, the air from the sea which is cooler and heavier rushes to take the place created by hot rising air. Therefore, a sea breeze blows during the day.

During the night, the land loses heat faster than water and becomes cooler and the air over the sea is now warmer due to which, it rises up and the cooler air over the land rushes to take its place. Therefore, we observe a land breeze at night.

3. Radiation
The mode of transfer of heat through which heat energy from a hot body to a cold body by means of heat rays without any material medium between them is known as radiation, e.g. the sun’s heat reaches the earth by the process of radiation. The sun is very far away from the earth, and there is mainly an empty space (vacuum) between the sun and the earth even, then the heat from the sun reaches the earth. This is due to the fact that the sun being extremely hot, emits invisible heat radiation (or infrared rays) in all directions.

These radiations travel through the vacuum between the sun and the earth at a very high speed and ultimately, reach us on the earth. Therefore, we can say that the transfer of heat from a hot object to a cold object by the process of radiation does not require any medium.

In our daily life activities, we have many situations where heat is transferred by radiation through air, e.g.

  • Depending on the temperature of surroundings, our body too gives heat to the surroundings or receives heat from the surroundings by radiation.
  • If a hot utensil filled with hot milk is kept away from the flame, then it cools down by transferring its heat to the surroundings by radiation.
  • If we stand next to a burning fire, then we will feel the heat of the fire falling on our face. The heat is transferred from the fire to our face by the process of radiation.

Clothes
During hot summer days, people prefer to wear white clothes or light coloured clothes because light coloured clothes absorb less heat from the sun and hence, keep us cool and comfortable in hot weather while in the cold winter days people prefer to wear dark clothes because the dark coloured clothes absorb more heat rays from the sun and keep us warm in winter season.

Thus, we can say that dark coloured objects absorb heat better and also emit heat better than light coloured objects. Now, let us try to study this concept on the basis of the given activity.

In the winters, we use woollen clothes. Wool is a poor conductor of heat. Moreover, there is air trapped in between the wool fibres. This air prevents the flow of heat from our body to the cold surroundings. So, we feel warm.

CBSE Class 8 Hindi Grammar अलंकार Pdf free download is part of NCERT Solutions for Class 8 Hindi. Here we have given NCERT Class 8 Hindi Grammar अलंकार.

CBSE Class 8 Hindi Grammar अलंकार

‘अलंकार’ में दो शब्द मिले हैं – अलम + कार
‘अलम्’ का अर्थ है – भूषण या सजावट।

इस प्रकार अलंकार का शाब्दिक अर्थ है – आभूषण अथवा जो अलंकृत या भूषित करे। इनके प्रयोग से भाषा चमत्कारी बनती है। ये भाषा में शब्द और अर्थ की दृष्टि से सौंदर्य उत्पन्न करते हैं। अलंकार के मुख्यतः दो भेद होते हैं।

  • शब्दालंकार
  • अर्थालंकार

1. शब्दालंकार – काव्य में जहाँ शब्दों के विशिष्ट प्रयोग से सौंदर्य और चमत्कार उत्पन्न होता है, वहाँ शब्दालंकार होता है, ‘कोमल कलाप कोकिल कामनीय कूकती थी। यहाँ ‘का’ वर्ण की आवृत्ति से शब्द के स्तर पर चमत्कार उत्पन्न किया गया है।

शब्दालंकार के भेद-

(i) अनुप्रास अलंकार – जब काव्य में एक ही वर्ण की आवृत्ति बार-बार होती है तो वहाँ अनुप्रास अलंकार होता है; जैसे

  • मुदित महीपति मंदिर आए। (म तथा ‘स’ वर्गों की आवृति) सेवक सहित सुमंत बुलाए।
  • तरनि तनूजा तट तमाल तरुवर बहु आए। (त वर्ण की आवृत्ति)
  • रघुपति राघव राजा राम (‘र’ वर्ण की आवृत्ति)
  • सुरभित सुंदर सुखद सुमन तुझ पर खिलते है। (‘स’ वर्ण की आवृत्ति)
  • कोमल कलाप कोकिल कमनीय कूकती थी (‘क’ वर्ण की आवृत्ति)

(ii) यमक अलंकार – जब कविता में किसी एक शब्द का एक से अधिक बार भिन्न-भिन्न अर्थों में प्रयोग होता हो, तब वहाँ
यमक अलंकार होता है; जैसे –
काली घटा का घमंड घटा।
यहाँ ‘घटा’ शब्द का प्रयोग दो बार हुआ है और दोनों बार उसका अलग अर्थ है। पहले ‘घटा’ का अर्थ ‘बादल’ और दूसरे घटा का अर्थ ‘कम होना है। अतः यहाँ यमक अलंकार है।
माला फेरत युग भया, फिरा न मन का फेर।
कर का मनका डारि दे, मन का मनका फेर।
यहाँ मनका शब्द का प्रयोग बार-बार हुआ है। दूसरे और चौथे ‘मनका’ अर्थ है- मोती अथवा माला का दाना। पहले और तीसरे ‘मन का’ का अर्थ है- हृदय का।

(iii) श्लेष अलंकार – जहाँ किसी शब्द की आवृत्ति एक ही बार में हो, पर उस शब्द के एक से अधिक अर्थ हो, वहाँ श्लेष अलंकार होता है; जैसे
जो रहीम गति की कुल कपूत गति सोच।
बारे उजियारो करै, बड़े अंधेरो होय।
बारे–जलने पर, होय होने पर, बड़े-बड़ा हो जाने पर बुझ जाने पर।
माँगने वाले को देखकर बार-बार वस्त्र देती है। माँगने वाले को देखकर बार-बार दरवाजा बंद कर लेती है।

2. अर्थालंकार – काव्य में जहाँ अर्थ के कारण विशेष सौंदर्य या चमत्कार उत्पन्न होता है, वहाँ अर्थालंकार होता है।
अर्थालंकार के चार भेद होते हैं।

  • उपमा अलंकार
  • रूपक अलंकार
  • उत्प्रेक्षा अलंकार
  • मानवी अलंकार

(i) उपमा अलंकार – उपमा का सामान्य अर्थ है – समानता या मिलता-जुलता रूप दिखाना।
जहाँ किसी एक वस्तु या व्यक्ति के गुणों की तुलना किसी दूसरी प्रसिद्ध वस्तु या व्यक्ति से की जाती है वहाँ उपमा अलंकार होता है; जैसे- हाय फूल-सी कोमल बच्ची, हुई राख की थी ढेरी।
यहाँ बच्चों की कोमलता की तुलना फूल की कोमलता से की गई है।
उपमा अलंकार में तुलना के लिए सा, सी, से जैसे योजकों का प्रयोग किया जाता है।

(ii) रूपक अलंकार – काव्य में जहाँ गुण, स्वभाव आदि की अत्यधिक समानता के कारण प्रस्तुत और (अप्रस्तुत) (उपमेय और उपमान) में भेद न दर्शाया जाए, उसे अभिन्न मान लिया जाए, तो वहाँ रूपक अलंकार होता है;
सामान्य शब्दों में उपमान और उपमेय को एक कर दिया है; जैसे
मैया मैं तो चंद्र खिलौना लै हों, चंद्रमा (उपमेय) में खिलौना (उपमान) का आनंद आरोपित है।
चरण कमल बन्दौ हरिराई (भगवान के चरणों (उपमेय) में कमल (उपमान) का आनंद आरोपित है।)

(iii) उत्प्रेक्षा अलंकार – जहाँ भिन्न होते हुए भी समानता प्रकट करने के लिए उपमेय में उपमान की कल्पना या संभावना प्रकट की जाए, वहाँ उत्प्रेक्षा अलंकार होता है; जैसे
सोहत ओढ़े पीत पट स्याम सलोने गात।।
मनहू नीलमनि सैल पर आतप पर्यो प्रभात।।
(श्रीकृष्ण के सुंदर साँवले रंग के शरीर में नील मणि पर्वत और उनके पीतांबर में प्रात:कालीन धूप की है।)

(iv) मानवीकरण अलंकार – जहाँ जड़ वस्तुओं या पदार्थों पर चेतन का आरोप हो अर्थात् प्रकृति के पदार्थों या तत्वों पर मानवीय भावनाओं या क्रियाओं का आरोप हो, वहाँ मानवीकरण अलंकार होता है। जैसे
अंबर पनघट में डुबों रही तारा घट उषा नागरी, प्रात:कालीन ‘उषा’ पर नगरी (चतुर स्त्री) का आरोप किया गया है।

(v) अतिशयोक्ति अलंकार – काव्य में जहाँ किसी व्यक्ति या वस्तु का वर्णन अत्यधिक बढ़ा-चढ़ाकर किया जाता हैं, वहाँ अतिशयोक्ति अलंकार होता है; जैसे-
हनुमान की पूँछ में, लगन न पाई आग।
लंका सिगरी जल गई, गए निसाचर भाग ।।
हनुमान की पूँछ में आग लगने से पूर्व ही सारी लंका के जल जाने का वर्णन किए जाने के कारण यहाँ अतिशयोक्ति अलंकार है।
