Formation of the Northern Plains
Formation of the Northern Plains : The Northern plains were formed as a result of the geological formation made during the different geological periods as well as a number of process like weathering, erosion and deposition. The work of weathering of rocks carved out by the stormy winds and the work of erosion and deposition carried out by the mighty rivers over a period of millions of years. The Himalayan uplift out of the Tethys 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 deposition of sediments by the river flowing from the mountains in the north and the peninsular plateau in the south. A flat land of extensive alluvial deposits led to the formation of the northern plains of India. The work of weathering by winds and of erosion and deposition by the mighty rivers is still going on and consequently the land is slowly and slowly advancing there by pushing the sea bed.
