Fold, Block, Volcanic
Mountains belts form when continents collide when separated by an ocean. When the plates collide and one sub ducts under the other the ocean basin closes. The oceanic crust thickens and forms waves that create mountains. The belts that are seen in the mountains are formed by the plates colliding.
