"The Indian subcontinent is part of a tectonic plate that has been moving for more than 200 million years. The plate was once attached to Australia and Antarctica. It separated and collided with Asia 50 million years ago. The land rippled up as the two landmasses met. That rippling is ongoing and is expected to continue for the next several million years. The land pushed skyward became the Himalayas, the world's highest mountain range."
