Answer:
India's
landmass has great contrasts as the Peninsular plateau in the South is a very
old landmass (65 million 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. Whereas the Himalayas have
lofty peaks and steep sided valleys, the Deccan region has gently rising ranges
and wide valleys. Thus, the Indian landmass shows a great physical contrast.
