Upwarped mountains are produced by a differential of pressure from inside the Earth that pushed the crust upwards. Fault-block mountains were formed by tectonic plate movement, folded mountain when two plates move together, while volcanic mountains are formed by a crack in the Earth known as volcanic vent.
