Answer 2

The Himalayan uplift out of the Thethy's sea and subsidence of the northern flank of the Peninsular plateau resulted in the formation of a large basin. In due course of time, this depression gradually got filled with the deposition of the sediment by the rivers flowing from mountains in the north. A flat land with extensive alluvial deposits by these rivers led to the formation of the Northern Plains of India.
