Major Landforms of the Earth - Chapter Wise CBSE Solved Question and Answer Based On NCERT
Points To Remember:
Landforms are shaped by two processes, which take place on the Earth’s crust. These processes include: Internal Process and External Process
Internal Process: It involves internal forces leading to the upliftment and subsidence of the Earth’s surface that finally results in the formation of landforms.
External Process: It involves external forces leading to the development of the landforms through wearing down and deposition.
Earth’s surface is being continuously changed by two external process- weathering and erosion
The rivers form the plains by eroding the slopes of mountains and carrying forward the eroded material. The load consisting of stones and sand is deposited along the course of rivers as well as in valleys forming the fertile plains.
A mountain is any natural elevation of earth surface. It may have a small summit and a broad base.
Block Mountains are steep-sided mountains that are formed at the places where a block of the Earth’s crust is squeezed upwards between two parallel fault lines. For example, Rhine Valley and Vosges Mountain in Europe.
Volcanic mountains are formed due to the deposition and solidification of volcanic lava, for example, Mt. Kilimanjaro in Africa and Mt. Fujiyama in Japan.
Plateaus are flat – topped tabled land that stands above the surrounding area. It is also known as high plateau or table land. For Example- Deccan Plateau in India, East African Plateau in Kenya etc.
