FIVE MARKS QUESTIONS
Question. Why is air travel more popular in the North Eastern states of India? Explain.

a. Big rivers: Presence of big rivers like Brahmaputra make it difficult to construct roads and railways. Airways are suitable when rivers get flooded.

2. Roads can traverse comparatively more dissected and undulating topography which is a limitation in case of railways.
3. Roads can negotiate higher gradients of slopes and as such can traverse mountains like the Himalayas, whereas the mountainous regions are unfavourable for the construction of railway lines due to high relief, sparse population and lack of economic opportunities Likewise, it is difficult to lay railway lines on the sandy plains in the deserts, swampy or forested tracks.
4. Road transport is economical in trans¬portation of few persons and relatively smaller amount of goods over short dis¬tances, whereas railways are suitable for transportation of large number of people and goods in bulk, especially over long distances.
5. Roadways provide door-to-door service, thus the cost of loading and unloading is much lower but railways have not reached ‘ everywhere, still there are places which are yet to be connected with the railways,
6. Road transport is also used as a feeder to other modes of transport such as they provide a link between railway stations, air and seaports. On the other hand, railways work as a lifeline for the economic growth of a country as they carry raw materials and produced goods from one part of the nation to another on a large scale.
