Earth scientists estimate that Everest is 50 to 60 million years old, a youngster by geological standards. The mountain was formed by the upward force generated when the Indian and Eurasian tectonic plates collided, pushing up the rocks that formed the highest mountain on Earth. That force is still at work today, pushing Everest’s summit about a quarter of an inch higher each year. ( Learn more about how mountains are formed.)
