Major Landforms of the Earth

Question:

What are the major landforms? Write about them in brief     [V. Imp.]

Answer:

The major landforms are mountains, plateaus and plains.
1.Mountains.They are natural elevation of the earth surface. They are higher than the surrounding area. Some mountains are veiy high. They are even higher than the clouds. Some mountains have permanently frozen rivers of ice known as glaciers. Mountains are generally thinly populated regions because the climate is harsh there. Farming is also not easily possible there. But mountains provide us water. They have a rich variety of flora and fauna.
2.Plateaus.They are usually flat-topped table land and are higher than the surrounding area. Plateaus may be young or old. The Deccan plateau in India is one of the oldest plateaus. Plateaus are very useful for mankind. They have rich deposits of minerals such as diamond, gold, iron, manganese etc. Several water falls can be found in the plateau regions.
3.Plains.They are vast stretches of flat land. They are mostly formed by rivers and their tributaries. Plains are usually fertile lands. Hence, thick population is found there. Construction of transport network is easy. Cultivation is also easy. Plains also provide level land for the construction of houses or buildings. In India, the Indo-Gangetic plains are the regions where one can find great concentration of population.
