The Himalayas, in southern Asia, rise higher than any other mountain range. Mount Everest, 8,850 m (29,035 ft) above sea level in the eastern Himalayas, is the highest point on Earth. In fact, the world’s 26 highest mountains, each rising more than 7,700 meters (25,300 feet), all lie in the Himalayas. About 50 million years ago, the Indian subcontinent collided with the rest of Asia.
This massive collision compressed Earth’s crust, forming the Himalayas (see Colliding Continents Map Trek). Continental collisions shaped all of the highest mountains of Eurasia, including the Caucasus and the Alps.
