Question 1.
Why is transportation necessary?
Answer:
Transportation is necessary:

1. for the movement of goods and services from their supply location to demand location, i.e. to link production centres with consumption centres.
2. for the movement of people from one region to the other.
3. for carrying out trade at all levels.
4. to supply goods, resources, etc. from the surplus regions to deficient regions.
5. for supplying relief measures to the regions where some natural calamities strike.
6. for transporting raw materials from mining regions and farms to the industries, etc.
   Efficient means of transport are the prerequisites for economic development of a nation.

Question 2.
What do you understand by means of transport? Write three important domains of the earth which are covered by them.
Answer:
Means of transport include all kinds of vehicles, trains, aeroplanes and ships. Means of transport are used for the movement of people, goods and services from one place to another. These are developed on three important domains of the earth, i.e., land, water and air. Based on these, transport can also be classified into land, water and air transport.

Question 3.
Today the world has become a “global village”. Justify this statement.
Answer:
Today the world has become a “large village” because of:

1. efficient and fast means of transport and
2. development of telecommunication and satellite communication systems.

These two functions, i.e. various means of transport and communication have reduced time and distance, have brought the world closer and the physical distances have become meaningless. For example, now trading from local levels has been extended to the international level and even financial transactions can take place round the world in no time. All this has been made possible because of efficient and quick means of transport and communication.

Question 4.
“Modern means of transport and communication serve as lifelines of our nation.” Justify this statement by giving supportive arguments.
Or

7. They link areas of production with consumption, i.e. agricultural farms are linked to the markets and industries.
8. They help in the balanced regional development of a country.
9. They play a very important role at the time of natural calamities, i.e., for providing relief measures.
10. Deficient areas can obtain resources from the regions of surplus, thereby making the interdependence among the regions possible.
11. They have added substantially to growing amenities and facilities for the comforts of life.

Question 5.
Why do the movement of goods and services form one place to another require fast and efficient means of transport? Explain with examples.
Answer:
Transport plays an important role in the economy. Because of transport raw materials reach the factory and finished products reach to the consumer. The pace of development of a country depends upon the production of goods and services as well as their movement over space. Today the world has converted into a large village with the help of efficient and fast moving transport:

1. Good transport helps in quick carrying of raw materials from remote areas to the production centre and allows distribution of goods efficiently.
2. Transport helps in the development of communication. Various means of communication help us in interacting with other people in all the parts of the world. It has brought the world closer.
3. Transport like railways helps us in conducting various activities like business, sight seeing, pilgrimages, etc.
4. Pipelines are used for transporting crude oil and natural gas to refineries and factories.
5. Water provides the cheapest means of transport and is useful for international trade.
