NCERT Solutions for Class 10 Social Geography Chapter 7 Lifelines of National Economy

Question-1
State any three merits of roadways.
Solution:
The growing importance of road transport is rooted in the following reasons:

The construction cost of roadways is much lower than that of the railways.
Its maintenance is also cheap and easy.
Roads can be built in mountainous areas. The roads can traverse comparatively more dissected and undulating topography.
Roads can negotiate higher gradients of slopes and as such can traverse mountains such as the Himalayas.
Road transport is economical in the transportation of a few persons and a relatively smaller amount of goods over short distances.
It provides door-to-door service, which results in a lower cost of loading and unloading.
It is used as a feeder to other modes of transport such as they provide a link between railway stations, air, and seaports.
Road transport connects fields with markets and factories.
Road transport is useful for the transport of perishable commodities.

Question-2:
Where and why is rail transport the most convenient means of transportation?
Solution:

Railways can transport larger number of goods and passengers over long distances at an economical cost. Hence, railways are the most convenient means of transport in the vast northern plains of India.
The flat terrain, dense population, rich agricultural resources and greater industrial activity have favoured the development of railways in this region.
The northern plains, therefore, have the densest railway network.
Railways have accelerated the development of industry and agriculture in this region
by providing quick availability of raw materials and distributing the finished products to the markets.
However, in spite of the fact that railways is the most convenient means of transportation in northern plains, a large number of rivers requiring construction of bridges across their wide beds posed some obstacles.

Globalisation includes the movement of capital as well as workers from one country to another country. The restrictions on the import of goods have been removed. Under World Trade

The organization, efforts are being made to have multi-lateral agreements for international trade. WTO is regulating the international trade of goods as well as services. Thus international trade has undergone a sea change. The export of agriculture and allied products, ores, minerals, gems, jewellary, chemicals and allied products, engineering goods, and petroleum products have increased. On the other hand import of petroleum and petroleum products, pearls and precious stones, inorganic chemicals, coal, coke have increased too.

The exchange of commodities and goods have been superseded by the exchange of information and knowledge. India has emerged as a software giant at the international level.
