Q. 1. How are the principal modes of world transportation complementary to one another? Explain with examples.
Ans.
Principal modes of transport are land, water and air. They are all complementary to one another:
(i) All modes of transport are used for inter- regional and intra-regional movement of goods and passengers.
(ii) International movement of goods is mainly handled by ocean freighters carried forward to the market/place of destination by roadways or railways.
(iii) Light weight/delicate goods are transported through airways which takes lesser time as compared to the other modes of transport. Then roadways provide the door to door facility to deliver the product to its destination.
(iv) Waterways carry heavy/bulky goods to their destinations only with the help of the land transport.
(v) Mainly land transport acts as a feeder to the airways and the waterways.

Q. 2. What is transport? How do the factors of demand and routes affect the transport services throughout the world? Explain with examples.
Ans. 
Transport is a service or facility for carrying persons and goods from one place to the other using humans, animals and different kinds of vehicles. Transportation is an organised service industry created to satisfy the basic needs of society. The significance of a mode depends on the type of goods and services to be transported, costs of transport and the mode available.
The factors of demand and routes that affect the transport services throughout the world are:
(i) International movement of goods is handled by ocean freighters.
(ii) Road transport is cheaper and faster over short distances and  for door-to door services.
(iii) Railways are most suited for large volumes of bulky materials over long distances within a country.
(iv) High-value, light and perishable goods are best moved by airways.

Q. 3. Describe the journey of development of land transport from the days of humans as carries and the cableways of today.
Ans.
L and transport is an important part of India’s economy as most of the movement of goods and services take place over land. In the early days human being themselves were carriers and use to carry the goods to smaller distances. Later animals were used to carry load and treated as beasts of burden. Invention of the wheel revolutionised the means of transport, engine-motors, cars and trucks, pipelines, ropeways and cableways have made the life of human easy.  
The revolution in transport came about only after the invention of the steam engine in the eighteenth century. Perhaps the first railway line was opened in 1825 between Stockton and Darlington in northern England and then on wards, railways became the most popular and fastest mode of transport in the nineteenth century.
Among the newer developments in land transportation are pipelines, ropeways, ocean vessels, cableways. Liquids like mineral oil, water, sludge and sewers are transported by pipelines.  In general, the old and elementary forms like the human porter, pack animal, cart of wagon are the most expensive means of land transportation and large freighters are the cheapest. They are important in supplementing modern channels and carriers which penetrate the interiors in large countries.

(v) The modern European network spans the entire continent and provides passenger and freight movement. There are significant high speed rail passengers networks.

Q. 17. Which continent has highest road density? Why do traffic congestions occur on road? Explain three measures to solve the problem to traffic congestions.
Ans.
North America.
When the road cannot cope up with the demands of traffic , congestion occurs. Number of private as well as commercial vehicle is rapidly increasing.  Construction of new roads or flyovers is not fusible to resolve this emerging traffic. Certain other things need to be done in order to solve the problem of traffic congestions. These can be:
(i) Use of public transport instead of private transport has to be encouraged. This will certainly make the difference.
(ii) Private vehicles should have some restrictions especially in peak hours.
(iii) Facilities in public transports should be increased so that it can attract huge amount of commuters.

Q. 18. Describe any five characteristics of highways of the world.
Ans. 
A highway is any public road or other public way on land. Major highways are often named and numbered by the governments that typically develop and maintain them. Major modern highways that connect cities in populous developed and developing countries help to enhance the road’s capacity, efficiency and safety to various degrees.
The characteristics of modern highways of the world are as follows:
(i) These are metalled roads that helps to connect distant places. This helps to procure raw materials easily. This promotes agricultural and industrial development.
(ii) These roads are more than 80 m wide and have several traffic lanes which enhance them to handle increased traffic capacity as compared to city or town streets.
(iii) Bridges, flyovers, embankments are common features at high speed. This helps to connect major industrial towns, agricultural centres, markets and ports. It also provides employment opportunities.
(iv) Highways have also indulged in environmental pollution due to increased vehicular movement and emission of smoke. Low quality roads can result in wear and tear of vehicles and accidents.

Q. 19. ‘Land transport plays a vital role in the development of trade and tourism in the world’. Support the statement with suitable examples.
Ans. 
Transport helps in the assembly of raw materials and distribution of finished goods. It makes possible to move goods from one place to another. In the earlier days, there were only local markets due to the absence of safe means of transport. Nowadays, trade is not restricted to the boundaries of a single country, but has spread throughout the world.
Development of efficient means of transport has knit together all the nations of the world into one big world market. Even the perishable articles like fish, dairy products, meat, etc., are being transported to distant places of the world. But without good transport facilities, such a development in trade and commerce would not have been possible.
For example: In India, there are many highways, linking the major towns and cities. Transportation also links diverse destinations and ferries people, commodities and services between these places. Tourism is much about travel and therefore the role of transportation in its operation is vital.
