Mount Everest grows by a small amount each year due to tectonic activity. 

Mount Everest is located in the Himalayas, where the Indian plate is colliding with the Eurasian plate. 

Mount Everest, the tallest mountain on Earth, grows about a quarter of an inch taller each year due to geological forces pushing the Indian plate beneath the Eurasian plate.

This collision causes the Earth's crust to buckle and fold, resulting in the upward growth of the Himalayan mountain range, including Mount Everest.

The Indian plate is slowly moving northward and colliding with the Eurasian plate at a rate of a few centimeters per year. 

This collision causes the Earth's crust to uplift, resulting in the gradual increase in height of the Himalayan mountains, including Mount Everest.
