Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges.
This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed] Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. These are also known as collision boundaries.

An orogenic belt, orogen, or mobile belt, [a] 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 .
The Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
Oregon was the No. 1 team ahead of Ohio State, Georgia and Miami. But the Buckeyes slot in at No. 5 in the projected playoff bracket. Unlike in the 10 previous years of the four-team playoff, ...
Land added to Laurentia during the Grenville orogeny. The first mountain-building tectonic plate collision that initiated the construction of what are today the Appalachian Mountains occurred during the Mesoproterozoic era at least one billion years ago when the pre-North-American craton called Laurentia collided with other continental segments, notably Amazonia.
