Question

Explain the formation of the Physical features of India on the basis of Plate Tectonic Theory.

Answer 1

1.The Indian Peninsula drifted towards the north and finally collided with the much larger Eurasian Plate.2.As a result of this collision, the sedimentary rocks which were accumulated in the geosynclines (known as Tethys) got folded and formed the mountain systems of the West Asia and Himalaya3.Due to the uplift of the Himalayas in the Tethys Sea, the northern part of the Indian Peninsula got subsided and formed a large basin. That basin was filled with sediments from the rivers which came from the mountains in the north and from the peninsula in the south.4.Thus, the northern plains of India came into existence. These plains are made up of alluvial deposits.5.The peninsular plateau is known as the old topography, whereas the Himalayas and the Northern plains are considered as new topography.The peninsular plateau is composed of igneous and metamorphic rocks with gently rising hills and wide valleys.
