  1. The convectional currents split the crust into a number of pieces.
  2. This leads to the drifting of the Indo-Australian plate after being separated from the Gondwana land, towards north.
  3. The northward drift resulted in the collision of the plate with the much larger Eurasian Plate
  4. Due to this collision, the sedimentary rocks which were accumulated in the geosynclines known as the Tethys were folded to form the mountain system of western Asia and Himalaya.

  2. In due course of time this depression, gradually got filled with deposition of sediments by the rivers flowing from the mountains in the north and the peninsular plateau in the south.
  3. A flat land of extensive alluvial deposits led to the formation of the northern plains of India.
