2. Answer the following questions in about 30 words:
Question 2.(i)
What are the problems of road transport in mountainous, desert and flood prone regions?
Answer:
Road transportation depends heavily on the physiography of nature. Mountainous regions: In mountainous regions, irregular terrain makes road construction difficult as cutting through the mountains while construction is not only costly but also dangerous. Also frequent landslides make the roads unfit for use. Desert regions: In desert regions, laying down of roads is not easy as sand does not provide with a strong base for construction of roads. Flood prone regions: In flood prone regions, roads are frequently flooded, hence they cannot be used and remain unfit for use.
Question 2.(ii)
What is a trans-continental railway?
Answer:
Trans continental railways connect two ends of a continent. They are instrumental in economic life of a country. They were constructed for economic and political reasons to facilitate long runs in different directions. They are essential for transportation of not only passengers but mainly of freight. Example; Trans continental Siberian railways.
Question 2.(iii)
What are the advantages of water transport?
Answer:
Water, transport is still the main means of transportation for bulky goods over long distances due to its efficiency. One of the great advantages of water transportation is that it does not require route construction. The oceans are linked with each other and are negotiable with ships of various sizes. All that is needed is to provide port facilities at the two ends. It is much cheaper because the friction of water is far less than that of land.
3. Answer the following questions in not more than 150 words:
Question 3.(i)
Elucidate the statement- “In a well managed transport system, various modes complement each other”.
Answer:
Transport is a service or facility for the carriage of persons and goods from one place to the other using humans, animals and different kinds of vehicles. Such movements take place over land, water and air. The significance of a mode depends on the type of goods and services to be transported, costs of transport and the mode available. International movement of goods is handled by ocean freighters. Road transport is cheaper and faster over short distances and for door- to-door services. Railways are most suited for large volumes of bulky materials over long distances within a country. High-value, light and perishable goods are best moved by airways.
None of the transport system is self-sufficient. For having a well-managed transportation system a proper link between all the modes is essential. Ports are a point of collection of goods carried by waterways; they must have efficient linkage with railways and roadways so that the goods can be taken to interiors. Railways are efficient in connecting far off places but they can’t penetrate deep into interiors or provide door to door service, for that an efficient road system along with transportation facilities like buses etc. should be available.
Question 3.(ii)
Which are the major regions of the world having a dense network of airways?
Answer:
Frequent air services are available to many parts of the world. Although, U.K. pioneered the use of commercial jet transport, U.S.A. developed largely postwar international civil aviation. Today, more than 250 commercial airlines offer regular services to different parts of the world. Recent developments can change the future course of air transport. Supersonic aircraft, cover the distance between London and New York within three and a half hours. In the Northern Hemisphere, there is a distinct east-west belt of inter-continental air routes. Dense network exists in Eastern U.S. A. Westen Fur ope and Southeast Asia. U.S.A. alone accounts for 60 per cent of the airways of the world. New York, London, Paris, Amsterdam, Frankfurt, Rome, Moscow, Karachi, New Delhi, Mumbai, Bangkok, Singapore, Tokyo, San Francisco, Los Angeles and Chicago are the nodal points where air routes converge or radiate to all continents.
Question 3.(iii)
What are the modes by which cyber space will expand the contemporary economic and social space of humans?
Answer:
Human beings have used different methods long-distance communications of which the telegraph and the telephone were important. The telegraph was instrumental in the colonization of the American West. The telephone became a critical factor in the urbanization of America. Even today, the telephone is the most commonly used mode. In developing countries, the use of cell phones, made possible by satellites, is important for rural connectivity. The world soon upgraded their copper cable systems to include optic fiber cables. These allow large quantities of data to be transmitted rapidly, securely, and are virtually error-free. Today internet is the largest electronic network on the planet connecting about 1,000 million people in more than 100 countries.
Artificial satellites, now, are successfully deployed in the earth’s orbit to connect even the remote comers of the globe with limited on-site verification. These have rendered the unit cost and time of communication invariant in terms of distance. Cyberspace is the world of electronic computerized space. It is encompassed by the Internet such as the World Wide Web (www). In simple words, it is the electronic digital world for communicating or accessing information over computer networks without physical movement of the sender and the receiver. It is also referred to as the Internet. Cyberspace exists everywhere. It may be in an office, sailing boat, flying plane and virtually anywhere.
There were less than 50 million Internet users in 1995, about 400 million in 2000 A.D. and over one billion in 2005. The next billion users are to be added by 2010.
As billions use the Internet each year, cyberspace will expand the contemporary economic and social space of humans through e-mail, e-commerce, e-leaning and e-governance. Internet together with fax, television and radio will be accessible to more and more people cutting across place and time. It is these modem communication systems, more than transportation that has made the concept of global village a reality.
