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.

Class 12 Geography Chapter 8 Long Answer Type Questions

Question 1.
What are advantages and disadvantages of road transport?
Answer:
Advantages:

• Most economical for short distance compared to railways.
• Freight transport by road is gaining importance as it offers door to door service.
• Roads are cheaper, easier and simple to construct and maintain than the railways.
• They can be taken through any terrains and negotiate bends unlike railways..
• Since railways cannot be taken to every corner, so roads play an important role in nation’s trade and commerce and for promoting tourism.

Disadvantages:

• Unmetalled roads are not effective and serviceable throughout the year, even the metalled roads become unmotorable during heavy rains and floods.
• Carrying capacity of roadways per vehicle is much lower than the railways.
• The quality of roads in the developing countries is not good as it requires heavy investment for construction and maintenance.
• City roads suffer from chronic traffic congestion. As a result of this most of the cities face the problem of traffic congestion.

Question 2.
Write a note on North American highways.
Answer:
In North America, highway density is high, about 0.65 km per sq km. Eveiy place is within 20 km distance from a highway. Cities located on the Pacific coast (west) are well-connected with those of the Atlantic Coast (east). Likewise, the cities of Canada in the north are linked with those of Mexico in the south. The Trans-Canadian Highway links Vancouver in British Columbia (west coast) to St. John’s City in Newfoundland (east coast) and the Alaskan Highway links Edmonton (Canada) to Anchorage (Alaska). The Pan-American Highway, a large portion of which has been constructed, will connect the countries of South America, Central America and U.S.A.-Canada.

Question 3.
Write a note on highways in Asia.
Answer:
In China, highways criss-cross the country connecting all major cities such as Tsungtso (near Vietnam boundary), Shanghai (central China), Guangzhou (south) and Beijing (north). A new highway links Chengdu with Lhasa in Tibet.

In India, there are many highways linking the major towns and cities. For example, National Highway No. 7 (NH 7), connecting Varanasi with Kanyakumari, is the longest in the country. The Golden Quadrilateral (GQ) or Super Expressway is underway to connect the six metropolitan cities — New Delhi, Mumbai, Bangalore, Chennai, Kolkata and Hyderabad. In Asia, highway network is most developed in India and China.

Question 4.
Write a note on railways in North America.
Answer:
North America has one of the most extensive rail networks accounting for nearly 40 per cent of the world’s total. In contrast to many European countries, the railways are used more for long-distance bulky freight like ores, grains, timber and machinery than for passengers. The most dense rail network is found in the highly industrialized and urbanized region of East Central U.S.A. and adjoining Canada. In Canada, railways are in the public sector and distributed all over the sparsely populated areas. The transcontinental railways carry the bulk of wheat and coal tonnage.

Question 5.
Give five important points on railways in Europe.
Answer:
Europe has one of the most dense rail networks in the world. There are about 4,40,000 km of railways, most of which is double or multiple-tracked. Belgium has the highest density of 1 km of railway for every 6.5 sq kms area. The industrial regions exhibit some of the highest densities in the world. The important rail heads are London, Paris, Brussels, Milan, Berlin and Warsaw.

Passenger transport is more important than freight in many of these countries. Underground railways are important in London and Paris’. Channel Tunnel, operated by Euro Tunnel Group through England, connects London with Paris. Trans-continental railway lines have now lost their importance to quicker and more flexible transport systems of airways and roadways.

In Russia, railways account for about 90 per cent of the country’s total transport with a very dense network west of the Urals. Moscow is the most important rail head with major lines radiating to different parts of the country’s vast geographical area. Underground railways and commuter trains are also important in Moscow. The Trans-Siberian railways and the Orient express are some of the important railways in the Europe.

Question 6.
Give the advantages of water transport.
Answer:
90-95% of the international trade is carried out through water transport. The energy cost of water transportation is lower. The oceans offer a smooth highway traversable in all directions with no maintenance costs. Winds and oceans currents help in movement of the oceanic vessels thus reducing the fuel cost of transportation.

Compared to land and air, ocean transport is a cheaper means of haulage (carrying of load) of bulky material over long distances from one continent to another. Modern passenger liners (ships) and cargo ships are equipped with radar, wireless and other navigation aids. The development of refrigerated chambers for perishable goods, tankers and specialised ships has also improved cargo transport. The use of containers has made cargo handling at the world’s major ports easier.

Water transport is the only means of transportation in dense tropical forest where roads and railways cannot be constructed. It is also the main mode of transportation for people living on islands as it is economic.
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. The energy cost of water transportation is lower. It is highly suitable for bulky and heavy commodities. It is eco friendly as ocean currents and winds help to a large extent in water transportation.

Question 7.
Write a note on the Mediterranean- Indian ocean sea route.
Answer:
This sea route passes through the heart of the Old World and serves more countries and people than any other route. Port Said, Aden, Mumbai, Colombo and Singapore are some of the important ports on this route. The construction of Suez canal has greatly reduced the distance and time as compared to the earlier route through the Cape of Good Hope. This trade route connects the highly industrialized Western European region with West Africa, South Africa, South-east Asia and the commercial agriculture and livestock economies of Australia and New Zealand. Before the construction of the Suez Canal this was the route connecting Liverpool and Colombo which was 6,400 km longer than the Suez Canal route. The volume of trade and traffic between both East and West Africa is on the increase due to the development of the rich natural resources such as gold, diamond, copper, tin, groundnut, oil palm, coffee and fruits.

Question 8.
Why cape of good hope sea route has less traffic?
Answer:
This sea route is another important one across the Atlantic Ocean which connects West European and West African countries with Brazil, Argentina and Uruguay in South America. The traffic is far less on this route because of the limited development and population in South America and Africa. Only southeastern Brazil and Plata estuary and parts of South Africa have large-scale industries. There is also little traffic on the route between Rio de Janeiro and Cape Town because both South America and Africa have similar products and resources.

Question 9.
Which canal has shortened the distance between Europe and Asia? Give five points on the canal.
Answer:
Suez canal has shortened the distance between Europe and Asia. This canal had been constructed in 1869 in Egypt between Port Said in the north and Port Suez in the south linking the Mediterranean Sea and the Red Sea.

• It gives Europe a new gateway to the Indian Ocean and reduces direct sea- route distance between Liverpool and Colombo compared to the Cape of Good Hope route.
• It is a sea-level canal without locks which is about 160 km and 11 to 15m deep.
• About 100 ships travel daily and each ship takes 10-12 hours to cross this canal.
• The tolls are so heavy that some find it cheaper to go by the longer Cape Route whenever the consequent delay is not important.
• A railway follows the canal to Suez, and from Ismailia there is a branch line to Cairo.
• A navigable fresh-water canal from the Nile also joins the Suez Canal in Ismailia to supply fresh-water to Port Said and Suez.

Question 10.
Which canal has shortened the distance between eastern and western coasts of North America? What is its economic significance?
Answer:.
Panama canal has shortened the distance between eastern and western coasts of North America. This canal connects the Atlantic Ocean in the east to the Pacific Ocean in the west.
Its economic significance are:

• The canal is about 72 km. long and involves a very deep cutting for a length of 12 km.
• It has a six lock system and ships cross the different levels (26 m up and down) through these locks before entering the Gulf of Panama.
• It shortens the distance between New York and San Francisco by 13,000 km by sea.
• Likewise the distance between Western Europe and the West-coast of U.S.A.; and North-eastern and Central U.S.A. and East and South-east Asia is shortened.
• The economic significance of this Canal is relatively less than that of the Suez. However, it is vital to the economies of Latin America.

Question 11.
Which is the most heavily used inland waterways in the world? Why is it important?
Answer:
Rhine waterway is the most heavily used inland waterways in the world. The Rhine flows through Germany and the Netherlands. It is navigable for 700 km from Rotterdam, at its mouth in the Netherlands to Basel in Switzerland. Ocean-going vessels can reach up to Cologne. The Ruhr river joins the Rhine from the east. It flows through a rich coalfield and the whole basin has become prosperous manufacturing area. Dusseldorf is the Rhine port for this region. Huge tonnage moves along the stretch south of the Ruhr. This waterway is the world’s most heavily used. Each year more than 20,000 ocean-going ships and 2,00,000 inland vessels exchange their cargoes. It connects the industrial areas of Switzerland, Germany, France, Belgium and the Netherlands with the North Atlantic Sea Route.

Question 12.

Answer:
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. As billions use the Internet each year, cyberspace will expand the contemporary economic and social space of humans through e-mail, e-commerce, e-leaming 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.

Question 15.
Which hemisphere is served more by the air transport? Why there is less development of it in the other hemisphere?
Answer:
Northern hemisphere is served more by the air transport. In the Northern Hemisphere, there is a distinct east-west belt of inter-continental air routes. Dense network exists in Eastern U.S.A., westren Europe 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. Africa, Asiatic part of Russia and South America lack air services. There are limited air services between 10-35 latitudes in the Southern hemisphere, due to sparser population, limited landmass and economic development.

Question 16.
Write a note on railways in Asia.
Answer:
In Asia, rail network is the most dense in the thickly populated areas of Japan, China and India. Other countries have relatively few rail routes. West Asia is the least developed in rail facilities because of vast deserts and sparsely populated regions. One of the most important railways of Asia is trans-Siberian Railways, a major rail route of Russia which runs from St. Petersburg in the west to Vladivostok on the Pacific Coast in the east passing through Moscow, Ufa, Novosibirsk, Irkutsk, Chita and Khabarovsk. It is the most important route in Asia and the longest (9,332 km) double-tracked and electrified trans-continental railway in the world.

It has helped in opening up its Asian region to West European markets. It runs across the Ural Mountains Ob and Yenisei rivers. Chita is an important agro-centre and Irkutsk, a fur centre. There are connecting links to the south, namely, to Odessa (Ukraine), Baku on the Caspian Coast, Tashkent (Uzbekistan), Ulan Bator (Mongolia), and Shenyang (Mukden) and Beijing in China. There is a proposal to build Trans Asiatic railway linking Istanbul with Bangkok via Iran, Pakistan, India, Bangladesh and Myanmar.

Question 17.
What is the latest development in the field of communication?
Answer:
Over the years human beings have used different methods long-distance communications of which the telegraph and the telephone were important. 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. Today there is a phenomenal pace of development. The first major breakthrough is the use of optic fiber cables (OFC). Faced with mounting competition, telephone companies all over 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. With the digitisation of information in the 1990’s, telecommunication slowly merged with computers to form integrated networks termed as Internet. Internet is the largest electronic network on the planet connecting about 1,000 million. As billions use the Internet each year, cyberspace will expand the contemporary economic and social space of humans through e-mail, e-commerce, e-learning 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.

Question 18.
Air transport has made world a global village. How? Also explain the significance of air transport.
Answer:
Air transport has brought about a connectivity revolution in the world in many ways. It is the fastest mode of transport. It is because of air transport that there is no place in the world which is more than 35 hours away. Significance of air transport can be understood as follows:

(a) Economic Significance:

• Air transport is used only for high value goods and passengers.
• Valuable goods can be moved rapidly.
• It is preferred for long distance travel.
• It is the easiest way to reach inaccessible areas such as mountainous snowfields or inhospitable deserts. In the Himalayan region, the routes are often obstructed due to landslides, avalanches or heavy snowfall. At such times, air travel is the only alternative to reach a place.

(b) Airways also have great strategic importance:

• Airports with wide facilities have to be built.
• The construction of airports and facilities is very costly. Therefore airports are built in places where the traffic is large.
• It requires large arrangements such as hanger, fuelling, landing facilities.
