What 3 type of plate colisions build mountains-

Collistion between continental and oceanic crust: As the oceanic crust was subducted pieces of crust called terranes were scraped off According to the microplate terrane theory, they became part of the continental crust.

Collision between oceanic crust and oceanic crust: As the oceanic plate subducts, water from the subducting lithosphere induces partial melting of mantle material to form magma.

Collision between continents: Mountains can also form when two coninents collide. the himalaya mountains were formed by just such a collision.
