how does the movement of tectonic plates create new mountains?

Answers

Answer:

For example, continental-continental convergence:

When continental plates collide, no subduction occurs as the plates are of similar buoyancy. However, the great amount of friction produced at the collision of plates causes the plates to fold and buckle, forming fold mountains.

It is friction between the moving plates as well as the build-up of sediments near the edges of the plates that causes mountains to be formed.
