44. Write a short note on types of mountains.
Answer: There are three types of mountains- Fold Mountains, Block Mountains and the Volcanic Mountains.
Fold Mountains – The Himalayan Mountains and the Alps are young fold mountains with rugged relief and high conical peaks. The Aravali range in India is one of the oldest fold mountain systems in the world. The range has considerably worn down due to the processes of erosion. The Appalachians in North America and the Ural mountains in Russia have rounded features and low elevation. They are very old fold mountains.
Block Mountains – Block Mountains are created when large areas are broken and displaced vertically. The uplifted blocks are termed as horsts and the lowered blocks are called graben. The Rhine valley and the Vosges Mountain in Europe are examples of such mountain systems.
Volcanic Mountains – Volcanic Mountains are formed due to volcanic activity. Mt.Kilimanjaro in Africa and Mt.Fujiyama in Japan are examples of such mountains.
45. Explain the major landforms of India?
Answer: We can group different landforms depending on elevation and slope as mountains, plateaus and plains.
Mountains – A mountain is any natural elevation of the earth surface. The mountains may have a small summit and a broad base. It is considerably higher than the surrounding area. Some mountains are even higher than the clouds. In some mountains, there are permanently frozen rivers of ice. They are called glaciers. There are some mountains you cannot see as they are under the sea. Because of harsh climate, less people live in the mountain areas. Since the slopes are steep, less land is available for farming.
Plateau – A plateau is an elevated flat land. It is a flat-topped table land standing above the surrounding area. A plateau may have one or more sides with steep slopes. The height of plateaus often varies from few hundred metres to several thousand metres. Plateaus, like mountains may be young or old. The Deccan plateau in India is one of the oldest plateaus. The Tibet plateau is the highest plateau in the world with a height of 4,000 to 6,000 metres above the mean sea level. Plateaus are very useful because they are rich in mineral deposits.
Plains – Plains are large stretches of flat land. They are, generally, not more than 200 metres above mean sea level. Some plains are extremely level. Others may be slightly rolling and undulating. Most of the plains are formed by rivers and their tributaries. Generally, plains are very fertile. Construction of transport network is easy. Thus, these plains are very thickly-populated regions of the world.
