Step-by-step explanation:
The mountain ranges like the Himalayas, where Mt. Everest is situated, and other bigger peaks are the outcomes of plate tectonics, resulting mainly due to huge slabs of Earth's crust colliding with each other. The point where collision takes place is known as a subduction zone, in which one of the subducts or slabs goes underneath, and the other gets on the top. When such kind of phenomenon take place, the push of one slab against the other, and the friction resulting on both the slabs lead to the formation of mountain ranges with the peaks like of Mt. Everest.
