Here's why:
* The Indian Plate is colliding with the Eurasian Plate.
* This collision is causing the land to buckle and fold upwards, creating the towering peaks of the Himalayas.
* This process is still ongoing, and the Himalayas continue to grow taller.
Other examples of mountain ranges formed by plate collisions include:
* The Andes Mountains (South America)
* The Alps (Europe)
* The Rockies (North America)
