2.Question.What is the difference between a mountain and a plateau?
Answer.
Mountain:
1.Mountain are the higher and steep landforms that extend above the surrounding areas.
2.Generally, mountains the landforms that rise above 600 meters.
3.Their elevation can exceed 8000 m.
4.Mountains are rich in forests.
5. More than half of the world's fresh water orginates in moutains.
6. Himalayas , Rockies and Andes are the main moutains in the world.
Plateau.
1.Plateau are the flat surfaced areas, bounded by steep slopes.
2.These are huge landforms. They cover hundreds or rven thousands of killometres.
3. Their elevation can exceed 4500m.
4. Plateau are the great reservoors of differnt minerals.
5. The rivers of plateau from waterfalls when they fall from a great height.
6. Deccan plateau, East africa plateau and Tibet are the major pleatues in the world.
(c) What are the different types of mountains?
Answer. The three types of mountains in the world.
These are the Fold moutain, Block mountain , Volcanic moutain.
(i) Fold mountain: They form when the earth's crust bends and buckles. Himalaya, Andes and Rockies are the main fold moutain.
(ii) Block Mountain: They form when the large areas are broken and displaced vertically. Vosges moutain of Europe is an example of block moutain.
(iii) Volcanic mountain: They form due to the volicanic activities. Mt.kilimanjaro in Africa and Mt.Fujiyama in Japan are the major volcanic moutains in the world.
(d) How are mountains are very useful to man?
Answer. Moutain are very useful to man because they are the large reservior of water.
They are the major sources of river and river water is widely used for irrigation purposes and in the production of hydroelectricity. Mountain are rich in variety of flora and fauna. They provide fuel, shelter, fodder and other forest products.
They also support tourism industry by giving scenioc beauty,clean air fresh climate.
They also encourage supports like skiing and moutain climbing.
(e) How plains are formed?
Answer. Plains are the flat and relatively low-lying areas of the earth's surface. These plains are formed by rivers their tributaries and distributries. The rivers flow down from moutains and erode them. They carry the eroded material ( stones,sand, silt) and deposit it along their courses or in their valleye. In this way, the plains are nformed with the help of deposit materials.
(f) Why are river plains thickly populated?
Answer. .Genrally, the plains are flat and made up of the fertile soil.So, they provide favourable conditions for agriculture. In plains rivers flow slowly. Therefore, it can be used for nagvigation. The construction of transport network is easy in flar areas. Due to these qualities, the river plains thickly populated.
(g) Why are mountains thinly populated?
Answer. Moutains are thinly populated because they have steep slopes and lack is good soil. these conditions are not favourable for ariculture.The steep slopes, on the other hand, make the tranportation and physical communication difficult. Mountains areas in the world are not much developed, so they can't prvide modern facilities to their people.
