Orogenic belt
Zone affected by mountain formation
An orogenic belt, orogen, or mobile belt,[lower-alpha 1] is a zone of Earth's crust affected by orogeny.[2] An orogenic belt develops when a continental plate crumples and is uplifted to form one or more mountain ranges; this involves a series of geological processes collectively called orogenesis.[3][4]
