    Question 122
    CBSEENSS10018058

    “Roadways still have an edge over railways in India.” Support the statement with arguments.

    Solution

    Roadways still have an edge over railways in India for the following reasons:

    i. It is because it is still the most common means of transport in the country.

    ii. The construction costs of roadways are much lower than the construction costs of railways.

    iii. While it is difficult to lay down railway lines in hilly tracts or mountainous regions, roads can be easily built in dissecting tracts of land.

    iv. Roads today connect even the smallest village to a large town. Railways have yet not been able to connect villages to cities.

    v. Roadways are economical in transporting few people and a small quantity of goods over short distances. Roads provide a link between various railway stations.

    Describe three major problems faced by the road transport in India. 

    Solution

    The problems faced:
    (i) The road network is inadequate, keeping in view the volume of traffic and passengers.

    (ii) Roadways are highly congested in cities and most of the bridges and culverts are old or narrow.

    (iii) About half of the roads are unmetalled and this limits their usage during the rainy season.

    Question 126
    CBSEENSS10018111

    Why is a dense and efficient network of transport and communication a perequisite for the development of local, national and global trade of today? Give your opinion. 

    Solution

    The opinions:

    (i) This is necessary to carry raw materials to production centres and from manufacturing hubs to markets in as little time as possible to achieve efficiency, especially for perishable goods.

    (ii) It enables goods to reach newer markets and allows people greater accessibility to goods and services. Efficient transport network enables markets to expand to hinterland.

    (iii) Technology has made much faster delivery of goods across long distances possible at lower costs.

    Question 127
    CBSEENSS10018120

    'Road transport and Rail transport in India are not competitive but complementary to each other.' Justify the statement.

    Solution
    India has the one of the largest road networks in the world. In India, roadways have preceded railways. They still have an edge over railways in views of the ease with which they can be built and maintained. But the growth of one means of transport cannot be attributed at the expense of another. Roadways and railways are complimentary to each other. Being a large country with diverse landforms, it is not possible to reach every corner of the country with rail network. In areas like hills and mountains, it is impossible to build railway lines. Hence, the only possible means to connect all such remote areas is by roads. While the railways connect the nodal points of our country, the roadways, on the other hand, extend this chain further to the hinterlands. This chain of networks helps our economy in two ways. Firstly, it facilitates bringing the raw materials for the industries from the hinterland to the factory sites and secondly, it helps in transporting the finished goods to the remotest parts of the country. Moreover, while road transport is economical in transportation of few persons and relatively smaller amount of goods and services over short distances, the railways, on the other hand, can be used for transportation of heavy cargo over long distances. Due to these reasons, road transport and rail transport in India are not competitive but complementary to each other.

    Question 136
    CBSEENSS10018243

    Why do the movement of goods and services from one place to another require fast and efficient means of transport. Explain with examples. 

    Solution

    Reasons for fast and efficient means of transport : 
    (i.) It is necessary to carry raw materials to production centers and from manufacturing hubs to markets in as little time as possible to achieve efficiency. This is particularly true for perishable goods. 
    (ii.) It enables goods to reach newer markets and allows people greater accessibility to goods and services. Efficient transport network enables markets to expand to hinterland. 
    (iii.) Communication opens new avenues of commerce. Modern communication tools like internet allow commercial transactions to take place over large distances, facilitating electronic commerce and banking across countries and contributing to integration of markets.

    Question 139
    CBSEENSS10018312

    'Roadways still have an edge over railways in India.' Support the statement with arguments. 

    Solution

    Advantages of roadways are as follows:- 

    • The construction cost of roads is much lower as compared to railway lines. 
    • Roads can traverse comparatively more dissected and undulating topography. 
    • Road transport is economical as it can transport less people and smaller amount of goods over short distances. 
    • Road transport is also used as a feeder to other modes of transport as they provide a link between railway stations, airports and sea ports.

     

    Question 140
    CBSEENSS10018329

    How are means of transport and communication complementary to each other? Explain with three examples.

    Solution

    Means of transport and communication are complementary to each other in the following

    three ways:

    i. Transport and communication establish links between production centres and consumption centres and provide the links through which these two centres carry out trade.

    ii. Such networks connect the remote pockets of the country with other parts. Hence, effective distribution of produced goods becomes possible.

    iii. The movement of raw material becomes much more efficient if there are elaborate means of transport and communications available.
