Esfera - Plate Techtonics

Great project, absolutely inspiring
More on mountains

Mountains are formed as volcanic, fold and block mountains. All result from plate tectonics. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features.

Over the course of many million years, these uplifted sections are eroded by the elements – wind, rain, ice and gravity and either will be found still near the original plate collision or overlap or sometimes a land mass can move away from the plates. I would expect volcanoes in the sea as islands where eruption has destroyed land and you could keep some of the islands if volcanic

The elements and glaciation gradually wear the surface of the mountains down creating a different shape and mountains to shrink but volcanoes can grow again on eruption

Volcanic Mountains:
Volcanic mountains are formed when a tectonic plate is pushed beneath another (or above a mid-ocean ridge or hotspot) where magma is forced to the surface

Fold Mountains:
Fold mountains occur when two tectonic plates collide at a convergent plate boundary, causing the crust to overthicken. This process forces the less dense crust to float on top of the denser mantle rocks eg the Zagros Mts

Block Mountains:
Block mountains are caused by faults in the crust, a seam where rocks can move past each other. Also known as rifting, this process occurs when rocks on one side of a fault rise relative to the other eg the Vosges Mts.
