Mountain formation refers to the geological processes that underlie the formation of mountains. These processes are associated with large-scale movements of the Earth's crust (tectonic plates). Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of … Ver mais There are five main types of mountains: volcanic, fold, plateau, fault-block and dome. A more detailed classification useful on a local scale predates plate tectonics and adds to these categories. Volcanic mountains Ver mais Hotspot volcanoes Hotspots are supplied by a magma source in the Earth's mantle called a mantle plume. Although originally attributed to a melting of subducted oceanic crust, recent evidence belies this connection.

Erosion ensued, creating a system of parallel valleys, wearing away the sediments on the surface, and exposing the billion-years-old rocks below.

Collisional tectonics give rise to mountain belts, because the crust becomes thicker than normal, and a crustal `root´ forms that will support the overlying mountains.
