The Indian Plate was once part of the supercontinent Gondwana, which began to break up during the Mesozoic Era.
The Indian subcontinent was formed when the Indian Plate collided with the Eurasian Plate.
It began to drift northward at a rate of roughly 20 cm per year, colliding with the Eurasian Plate some 55 million years ago.
Furthermore, the Himalayas, the world's greatest mountain range, rose as a result of the collision of the two plates.
The Indian Plate is still moving northward today, forcing the Himalayas to rise.
