Zard-Kuh, a fold mountain in the central Zagros range of Iran. When plates collide or undergo subduction (that is, ride one over another), the plates tend to buckle and fold, forming mountains. While volcanic arcs form at oceanic-continental plate boundaries, folding occurs at continental-continental plate boundaries.
Fold mountains form in areas of thrust tectonics, such as where two tectonic plates move towards each other at convergent plate boundary.When plates and the continents riding on them collide or undergo subduction (that is – ride one over another), the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak ...
Massif – The principal mass of a mountain; Meander – One of a series of curves in a channel of a matured stream; Mesa – Elevated area of land with a flat top and sides, usually much wider than buttes; Mid-ocean ridge – Basaltic underwater mountain system formed by plate tectonic spreading
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 involves a series of geological processes collectively called ...
Mountains and hills can be characterized in several ways. Some mountains are volcanoes and can be characterized by the type of lava and eruptive history. Other mountains are shaped by glacial processes and can be characterized by their shape. Finally, many mountains can be characterized by the type of rock that make up their composition.
The most popular route up Mount Moran is the CMC route, named for the Chicago Mountaineering Club. The CMC is rated 5.5, and ascends the east face just south of the Black Dike. The CMC climbs good rock and is essentially free of snow and ice. It also has the advantage of a good camp high on the flank of the mountain. [5]

Block mountains are caused by faults in the crust: a plane where rocks have moved past each other. When rocks on one side of a fault rise relative to the other, it can form a mountain. [24] The uplifted blocks are block mountains or horsts. The intervening dropped blocks are termed graben: these can be small or form extensive rift valley systems.
