1.	How does the Indian landmass display a great physical contrast?
Answer» India’s landmass has great contrasts, like\xa0the Peninsular\xa0plateau in the South is a very old landmass (65 million\xa0years), whereas the Himalayas in the North are fairly\xa0new about 25 million years). Tectonically, the Himalayas and the Northern Plains\xa0are unstable zones, whereas the Peninsular plateau is\xa0very stable. Over millions of years, weathering forces\xa0have made the contrast sharper. While the Himalayas\xa0are composed of\xa0sedimentary and metamorphic rocks\xa0and the Northern\xa0Plains are made of deposited\xa0alluvium, the Peninsular plateau is made up of igneous\xa0alluvium, the Peninsular plateau is made up of igneous\xa0lofty peaks and steep-sided valleys, the Deccan region\xa0has gently rising ranges and wide valleys. Thus, the\xa0Indian landmass shows great physical contrast.
