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 ...
Illustration of mountains that developed on a fold that thrusted. Mountain formation occurs due to a variety of geological processes associated with large-scale movements of the Earth's crust (tectonic plates). [1] Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of mountain ...

The Ouachita Mountains (/ ˈ w ɒ ʃ ɪ t ɔː /), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America . [ 3 ]
This is a stylized illustration of the Southern African Great Escarpment, based particularly on its appearance in the Great Karoo, where thick erosion resistant dolerite sills (represented by the thick black lines in the diagram) generally form the upper, sharp edge of the escarpment; in other parts of the escarpment hard erosion-resistant geological layers similarly form the upper, abrupt ...
Active peat building is still occurring at some sites, most notably the Liffey Head Bog. [64] Common heather (or ling) and bell heather are the most common moorland plants along with bilberry (or fraughan, as it is known in Ireland), bog cotton, deergrass and purple moor grass. [68]

A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny . [ 1 ]
