Detailed explanation-1: -It began moving north, at about 20 cm (7.9 in) per year, and is believed to have begun colliding with Asia as early as 55 million years ago, in the Eocene epoch of the Cenozoic. However, some authors suggest the collision between India and Eurasia occurred much later, around 35 million years ago.

Detailed explanation-2: -If we conclude that India and Eur asia collided 40 million years ago.

Detailed explanation-3: -Plate tectonics. The collision of India with Asia-dubbed “the collision that changed the world” by legendary geoscientist Wally Broecker, a founder of modern climate research-closed off an ancient sea called the Tethys, disturbing the continental shelves and their connections with the open ocean.
