> The Himalayas and the Tibetan Plateau to the north have risen very rapidly. In just 50 million years, peaks such as Mt. Everest have risen to heights of more than 9 km. The impinging of the two landmasses has yet to end. The Himalayas continue to rise more than 1 cm a year -- a growth rate of 10 km in a million years! If that is so, why aren't the Himalayas even higher? Scientists believe that the Eurasian Plate may now be stretching out rather than thrusting up, and such stretching would result in some subsidence due to gravity.[1] EDIT: Gravitational deformation creates a maximum bound near Himalayan height. But actual height below that is apparently a mix of tectonic support from the sides, above-snowline erosion, and boat floating on mantle.[2] [1] https://pubs.usgs.gov/gip/dynamic/himalaya.html https://pubs.usgs.gov/gip/dynamic/himalaya.html [2] https://www.nature.com/articles/d41586-020-01601-4 https://www.nature.com/articles/d41586-020-01601-4 Sci-hub doesn't have the underlying paper yet.
