The Indian landmass shows a great physical contrast. Justify the statement.
The land of India displays a great physical variation. This can be explained in the following ways:
India’s landmass has great contrasts, as the Peninsular plateau in the South is a very old landmass (65 milion years), whereas the Himalayas in the North are fairly new (about 25 million years).
Tectonically, the Himalayas and the Northern plains are unstable zones, whereas the Peninsular plateau is very stable.
Over millions of years, weathering forces have made the contrast sharper. While the Himalayas are composed of sedimentary and metamorphic rocks and the Northern plains are made of deposited alluvium, the Peninsular plateau is made up of igneous and metamorphic rocks.
The Himalayas have high peaks, deep valleys and fast flowing rivers whereas the Deccan region has gently rising ranges and wide valleys.
Thus, the Indian landmass shows a great physical contrast.
