Question 3.(i)
Differentiate between primary and secondary activities.
Answer:

Question 3.(ii)
Discuss the major trends of modem industrial activities especially in the developed countries of the world.
Answer:
Major concentrations of modern manufacturing have flourished in a few number of places. These cover less than 10 per cent of the world’s land area. These nations have become the centres of economic and political power. However, in terms of the total area covered, manufacturing sites are much less conspicuous and concentrated on much smaller areas than that of agriculture due to greater intensity, of processes. For example, 2.5 sq km of the American corn belt usually includes about four large farms employing about 10-20 workers supporting 50¬100 persons. But this same area could contain several large integrated factories and employ thousands of workers.

Following are the characteristics of the modem industries in the modern world:

Mechanisation: Mechanisation refers to using gadgets which accomplish tasks. Automation (without aid of human thinking during the manufacturing process) is the advanced stage of mechanisation.
Technological Innovation: Technological innovations through research and development strategy are an important aspect of modern manufacturing for quality control, eliminating waste and inefficiency, and combating pollution.
Organisational Structure and Stratification:
Modern manufacturing is characterized by:

• a complex machine technology extreme specialisation and division of labour for producing more goods with less effort, and low costs.
• vast capital
• large organisations
• executive bureaucracy.

Development of high tech industries and technopolies: High technology, or simply high-tech, is the latest generation of manufacturing activities. It is best understood as the application of intensive research and development (R and D) efforts leading to the manufacture of products of an advanced scientific and engineering character. Robotics on the assembly line, computer -aided design (CAD) and manufacturing, electronic controls of smelting and refining processes, and the constant development of new chemical and pharmaceutical products are notable examples of a high-tech industry.

High-tech industries which are regionally concentrated, self-sustained and highly specialised are called technopolies. The Silicon Valley near San Francisco and Silicon Forest near Seattle are examples of technopolies.

Offshoring: Most of the industries in the developed countries are seeking and establishing their back office operations in third world countries where the work force is available in abundance at a cheaper rate. The government in the countries where they set up their operations is also eager to accommodate them with relaxed policies so as to generate employment.

Agglomeration economies: The present times also happen to be a high for agglomeration economies and industrial hubs where different related industries localize themselves close to each other in order to maximize profits and reduce overheads,

Question 3.(iii)
Explain why high-tech industries in many countries are being attracted to the peripheral areas of major metropolitan centers ?
Answer:
High technology, or simply high tech, is the latest generation of manufacturing activities. Professional workers make up for a large number of the total workforce. These professional skilled workers are located in urban areas, and due to high rent in the central areas of the cities, they situate themselves in the periphery.

The industry is also situated in the periphery because of the low rent, and also because of the closeness to the urban centres which provide them with availability of the workers. Neatly spaced, low, modem, dispersed, office-plant-lab buildings rather than massive assembly structures, factories and storage areas mark the high-tech industrial landscape.

This requires large areas for massive set up which due to increased population in major metropolitan cities is not available. Hence, these industries are set up near the urban centers where adequate space is available. Also their situation near urban places helps them to gain access to the-urban market, and also to tap the skilled workforce that is available therein due to availability of educational institutes.
Example in case would be Gurgaon in Haryana, which has grown into one of the greatest high tech hub near Delhi.

Question 3.(iv)
Africa has immense natural resources and yet it is industrially the most backward continent. Comment.
Answer:
Although Africa has natural resources in abundance in terms of its land resources, its forest and water resources, its mineral and energy resources, the most important component to transfer these into usable form- the human resource, is not well developed. All the characteristics that mark an industrially developed nation are lacking. The following discussion would make it amply clear why Africa remains industrially backward.

• Specialization of skills/methods of production: African industries still use primitive methods of production, which makes its yield low. Lack of adequate training and opportunities forces most of the African state to have low skilled human capital and most of the workforce remains to be unskilled.
• Mechanization and Technological innovation: Low level of mechanization leads to a cut in the production level and as the industries in Africa are generally not connected with the other competing industries in the world, sharing of technology does not take place in a greater scale and therefore innovation, which is the important for the progress of industries, does not take place.
• Organizational structure and stratification: A high level of organization and an efficient division of labour is essential for the thriving of giant enterprises. They lack in the said continent.
• Access to market and raw material: For basic industries, it is important that the raw materials are easily accessible to the factories of production, and the finished goods should find easy access to markets. This however, lacks because of the lack of good transport network, effective communication facilities and international markets.
• Access to labour supply: Although Africa is quite populous and blue collar workers are available aplenty, skilled labour is in a shortage, which makes industries suffer further on managerial and technological fronts.
• Government policy: Because of the political turmoil that go on in most of the African nations, a long term and healthy government policy towards the progress of industries is absent, thus making it a push factor for foreign multinationals to invest in the said areas. This in turn acts as a repelling factor for the formation of agglomeration economies, which are vital for the sharing of technological innovation between different industries.
• Transportation facilities: Development of modem industries requires well transport linkage, so that agglomeration economies can be created. Also it is necessity for development of trading network both at national as well as international level. Africa lacks development of adequate network of highways, railways and airway linkage.

The Ruhr region is responsible for 80% of Germany’s steel production.

Question 13.
What are mini steel plants?
Answer:
These are less expensive to build and operate and can be located near markets because of the abundance of scrap metal, which is the main input. Traditionally, most of the steel was produced at large integrated plants, but mini mills are limited to just one-step process steel making and are gaining ground.

Class 12 Geography Chapter 6 Short Answer Type Questions

Question 1.
What are footloose industries?
Answer:
Footloose industries can be located in a wide variety of places. They are not dependent on any specific raw material, weight losing or otherwise. They largely depend on component parts which can be obtained anywhere. They produce in small quantity and also employ a small labour force. These are generally not polluting industries. The important factor in their location is accessibility by road network.

Question 2.
Discuss three sub-sectors of cotton textile industry.
Answer:
Cotton textile industry has three sub¬sectors i.e. handloom, power loom and mill sectors.

• Hand loom sector is labour intensive and provides employment to semi skilled workers. It requires small capital investment. This sector involves spinning, weaving and finishing of the fabrics.
• The powerloom sector introduces machines and becomes less labour intensive and the volume of production increases.
• Cotton textile mill sector is highly capital intensive and produces fine clothes in bulk.

Question 3.
What is an industry? Classify industry based on output.
Answer:
An industry is a geographically located manufacturing unit maintaining books of accounts and, records under a management system. As the term industry is comprehensive, it is also used as synonymous with ‘manufacturing’. When one uses terms like ‘steel industry’ and ‘chemical industry’ one thinks of factories and processes. Based on output there are two types of industries:

• Basic industries: The industry whose products are used to make other goods by using them as raw materials are basic industries. Eg. Iron and steel industry for making machineries for textile industries to make clothes.
• Consumer goods industries: The consumer goods industries produced goods which are consumed by consumers directly. Example, industries producing breads and biscuits, tea, soaps and toiletries, paper for writing, televisions, etc. are consumer goods or non-basic industries.

Question 4.
Classify industry based on ownership.
Answer:
Based on ownership, industries are classified as:

• Public Sector Industries are owned and managed by government. In India, there were a number of Public Sector Undertakings (PSUs). Socialist countries have many state owned industries. Mixed economies have both Public and Private sector enterprises.
• Private Sector Industries are owned by individual investors. These are managed by private organisations. In capitalist countries, industries are generally owned privately.
• Joint Sector Industries are managed by joint stock companies or sometimes the private and public sectors together establish and manage the industries.

Question 5.
What are the characteristics of traditional large scale industrial region?
Answer:
Traditional large scale industrial regions are based on heavy industry, often located near coal-fields and engaged in metal smelting, heavy engineering, chemical manufacture or textile production. These industries are now known as smokestack industries. Traditional industrial regions can be recognized by:

• High proportion of employment in manufacturing industry. High-density housing, often of inferior type, and poor services. Unattractive environment, for example, pollution, waste heaps, and so on.
• Problems of unemployment, emigration and derelict land areas caused by closure of factories because of a worldwide fall in demand.

Class 12 Geography Chapter 6 Long Answer Type Questions

Question 1.
Discuss the major trends of modern industrial activities especially in the developed countries of the world.
Answer:
Traditional large scale industries were based on heavy industry, often located near coal-fields and engaged in metal smelting, heavy engineering, chemical manufacture or textile production. These industries are now known as smokestack industries. With modernization, there has been changes in industrial sector which have led to the decay of some areas, and there are problems of industrial waste and pollution. The future prosperity of these traditional areas has shifted from their traditional activities to high technology, or simply high-tech, which is the latest generation of manufacturing activities. It is best understood as the application of intensive research and development (R and D) efforts leading to the manufacture of products of an advanced scientific and engineering character.

Robotics on the assembly line, computer- aided design (CAD) and manufacturing, electronic controls of smelting and refining processes, and the constant development of new chemical and pharmaceutical products are notable examples of a high-tech industry. Neatly spaced, low, modem, dispersed, office-plant-lab buildings rather than massive assembly structures, factories and storage areas mark the high-tech industrial landscape. The Silicon Valley near San Francisco and Silicon Forest near Seattle are examples of technopolies. The traditional industrial regions have shifted their focus from traditional large scale industries to assembly plants (footloose industries), new chemical plants, universities, out of town shopping centres etc.

Question 2.
Give a brief account on the following:
(a) Iron and Steel industry
(b) Cotton Textile Industry
Answer:
(a) The iron and steel industry:
It forms the base of all other industries and, therefore, it is called a basic industry. It is basic because it provides raw material for other industries such as machine tools used for further production. It may also be called a heavy industry because it uses large quantities of bulky raw materials and its products are also heavy. Iron is extracted from iron ore by smelting in a blast furnace with carbon (coke) and limestone. The molten iron is cooled and moulded to form pig iron which is used for converting into steel by adding strengthening materials like manganese. The large integrated steel industry is traditionally located close to the sources of raw materials – iron ore, coal, manganese and limestone – or at places where these could be easily brought, e.g. near ports. But in mini steel mills access to markets is more important than inputs.

Distribution: This industry is one of the most complex and capital-intensive industries and is concentrated in the advanced countries of North America, Europe and Asia. In U.S.A, most of the production comes from the north
Appalachian region (Pittsburgh), Great Lake region. The industry has also moved towards the southern state of Alabama. Pittsburg area is now losing ground. It has now become the “rust bowl” of U.S.A. In Europe, U.K., Germany, France, Belgium, Luxembourgh, the Netherlands and Russia are the leading producers. In Asia, the important centres include Nagasaki and Tokyo-Yokohama in Japan; Shanghai, Tienstin and Wuhan in China; and Jamshedpur, Kulti-Bumpur, Durgapur, Rourkela, Bhilai, Bokaro, Salem, Visakhapatnam and Bhadravati in India centres.

(b) Cotton textile industry:
Cotton textile industry has three sub¬sectors i.e. handloom, powerloom and mill sectors. Handloom sector is labour¬intensive and provides employment to semi-skilled workers. It requires small capital investment. This sector involves spinning, weaving and finishing of the fabrics. The powerloom sector introduces machines and becomes less labour intensive and the volume of production increases. Cotton textile mill sector is highly capital intensive and produces fine clothes in bulk. Cotton textile manufacturing requires good quality cotton as raw material. India, China, U.S.A, Pakistan, Uzbekistan, Egypt produce more than half of the world’s raw cotton. The U.K, NW European countries and Japan also produce cotton textile made from imported yam. Europe alone accounts for nearly half of the world’s cotton imports.

The industry has to face very stiff competition with synthetic fibres hence it has now shown a declining trend in many countries. With the scientific advancement and technological improvements the structure of industries changes. For example, Germany recorded constant growth in cotton textile industry since Second World War till the seventies but now it has declined. It has shifted to less developed countries where labour costs are low.

Question 3.
Define manufacturing. List the characteristics of modern large scale manufacturing.
Answer:
Manufacturing literally means “to make by hand’. However, now it includes goods ‘made by machines’. It is essentially a process which involves transforming raw materials into finished goods of higher value for sale in local or distant markets. Modern large scale manufacturing has the following characteristics: Specialization of Skills/Methods of Production: Under the ‘craft’ method factories produce only a few pieces which are made-to-order. So the costs are high. On the other hand, mass production involves production of large quantities of standardized parts by each worker performing only one task repeatedly.

Mechanization: Mechanization refers to using gadgets which accomplish tasks. Automation (without aid of human thinking during the manufacturing process) is the advanced stage of mechanization. Technological Innovation: Technological innovations through research and development strategy are an important aspect of modern manufacturing for quality control, eliminating waste and inefficiency, and combating pollution. Organisational Structure and Stratification: Modern manufacturing is characterized by:

• a complex machine technology
• extreme specialization and division of labour for producing more goods with less effort, and low costs
• vast capital
• large organisations
• executive bureaucracy.

Question 4.
Describe the factors that affect the location of industries.
Answer:
Major concentrations of modern manufacturing have flourished in a few number of places. These cover less than 10 per cent of the world’s land area. These nations have become the centres of economic and political power. Industries maximise profits by reducing costs. Therefore, industries should be located at points where the production costs are minimum. Some of the factors influencing industrial locations are as under: Access to Market: The existence of a market for manufactured goods is the most important factor in the location of industries. ‘Market’ means people who have a demand for these goods and also have the purchasing power (ability to purchase) to be able to purchase from the sellers at a place. Remote areas inhabited by a few people offer small markets. The developed regions of Europe, North America, Japan and Australia provide large global markets as the purchasing power of the people is very high. The densely populated regions of South and South-east Asia also provide large markets.

Access to Raw Material: Raw material used by industries should be cheap and easy to transport. Industries based on cheap, bulky and weight-losing material (ores) are located close to the sources of raw material such as steel, sugar, and cement industries. Perishability is a vital factor for the industry to be located closer to the source of the raw material. Agro-processing and dairy products are processed close to the sources of farm produce or milk supply respectively. Access to Labour Supply: Labour supply is an important factor in the location of industries. Some types of manufacturing still require skilled labour. Increasing mechanization, automation and flexibility of industrial processes have reduced the dependence of industry upon the labours. Access to Sources of Energy: Industries which use more power are located close to the source of the energy supply such as the aluminium industry. Earlier coal was the main source of energy, today hydroelectricity and petroleum are also important sources of energy for many industries.

Access to Transportation and Commu-nication Facilities: Speedy and efficient transport facilities to carry raw materials to the factory and to move finished goods to the market are essential for the development of industries. The cost of transport plays an important role in the location of industrial units. Communication is also an important need for industries for the exchange and management of information. Government Policy: Governments adopt ‘regional policies’ to promote ‘balanced’ economic development and hence set up industries in particular areas.
Access to Agglomeration Economies/ Links between Industries: Many industries benefit from nearness to a leader-industry and other industries. These benefits are termed as agglomeration economies. These factors operate together to determine industrial location.

Question 5.
Classify industry based on inputs. Ans. On the basis of the raw materials used, the industries are classified as:
(a) agro-based
(b) mineral based
(c) chemical based
(d) forest based and
(e) animal based.
Answer:
(a) Agro based Industries:
Agro processing involves the processing of raw materials from the field and the farm into finished products for rural and urban markets. Major agro-processing industries are food processing, sugar, pickles, fruits juices, beverages (tea, coffee and cocoa), spices and oils fats and textiles (cotton, jute, silk), rubber, etc. Food and Agro processing includes canning, producing cream, fruit processing and confectionary. While some preserving techniques, such as drying, fermenting and pickling, have been known since ancient times, these had limited applications to cater to the pre-industrial Revolution demands.
(b) Mineral based Industries:
These industries use minerals as a raw material. Some industries use ferrous metallic minerals which contain ferrous (iron), such as iron and steel industries but some use non-ferrous metallic minerals, such as aluminium, copper and jewellery industries. Many industries use non-metallic minerals such as cement and pottery industries.
(c) Chemical based Industries:
Such industries use natural chemical minerals, e.g. mineral-oil (petroleum) is used in petrochemical industry. Salts, sulphur and potash industries also use natural minerals. Chemical industries are also based on raw materials obtained from wood and coal. Synthetic fibre, plastic, etc. are other examples of chemical based industries.
(d) Forest based raw Material using Industries:
The forests provide many major and minor products which are used as raw material. Timber for furniture industry, wood, bamboo and grass for paper industry, lac for lac industries come from forests.
(e) Animal based Industries:
Leather for leather industry and wool for woollen textiles are obtained from animals. Besides, ivory is also obtained from elephant’s tusks.

Question 6.
Give the characteristics of hightech industries.
Answer:
High technology, or simply high-tech, is the latest generation of manufacturing activities. It is best understood as the application of intensive research and development (R and D) efforts leading to the manufacture of products of an advanced scientific and engineering character. Professional (white collar) workers make up a large share of the total workforce. These highly skilled specialists greatly outnumber the actual production (blue collar) workers.

Robotics on the assembly line, computer-aided design (CAD) and manufacturing, electronic controls of smelting and refining processes, and the constant development of new chemical and pharmaceutical products are notable examples of a high-tech industry. Neatly spaced, low, modern, dispersed, office-plant-lab buildings rather than massive assembly structures, factories and storage areas mark the high-tech industrial landscape. Planned business parks for high-tech start-ups have become part of regional and local development schemes.

High-tech industries which are regionally concentrated, self-sustained and highly specialized are called technopolies. The Silicon Valley near San Francisco and Silicon Forest near Seattle are examples of technopolies. Bangalore is known as Silicon Valley of India.
