Why does Mount Everest keep growing?
Quick fact
The Indian tectonic plate continues to collide with the Eurasian plate, pushing the Himalayas upward at a rate of 0.5 to 1 cm per year.
Why this is interesting
Mount Everest isn't finished climbing—it rises by about 4 millimeters every year, the same speed your fingernails grow.

Understanding Why does Mount Everest keep growing?
Everest's height is the net result of two opposing forces: tectonic uplift (pushing up) and erosion (wearing down). Currently, uplift is winning, so the mountain grows taller.
A deeper explanation
This collision began about 50 million years ago, and Everest's current height (8,848.86 meters) is a snapshot in an ongoing process. Interestingly, the uplift isn't uniform; some parts of the Himalayas rise faster due to local crustal deformations. Meanwhile, human activity like heavy metal pollution from tourism has recently been detected in the ice—but that doesn't affect the geology. The summit is also moving northeastward at about 5 cm per year due to the same tectonic drift. So Everest is not only getting taller but is also slowly relocating, making its coordinates the only moving 'world record' on the planet.
