The name comes from the German word fliessen, which means to flow, because Studer thought flysch was deposited by rivers. The insight that flysch is actually a deep marine sediment typical for a particular plate tectonic setting came only much later. [5] The name flysch is currently used in many mountain chains belonging to the Alpine belt.
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.

Moulin – Shaft within a glacier or ice sheet which water enters from the surface; Mountain – Large natural elevation of the Earth's surface; Mountain pass – Route through a mountain range or over a ridge; Mountain range – Geographic area containing several geologically related mountains; Nunatak – Landform within an ice field or glacier
A team led by Marie Tharp and Bruce Heezen concluded that there was an enormous mountain chain with a rift valley at its crest, running up the middle of the Atlantic Ocean. Scientists named it the 'Mid-Atlantic Ridge'. Other research showed that the ridge crest was seismically active [45] and fresh lavas were found in the rift valley. [46]
A water gap is a gap that flowing water has carved through a mountain range or mountain ridge and that still carries water today. [1] Such gaps that no longer carry water currents are called wind gaps. Water gaps and wind gaps often offer a practical route for road and rail transport to cross the mountain barrier.
Location map of the Paradox Basin [1] The Paradox Basin is an asymmetric foreland basin located mostly in southeast Utah and southwest Colorado, but extending into northeast Arizona and northwest New Mexico. The basin is a large elongate northwest to southeast oriented depression formed during the late Paleozoic Era.
The Exquisite Mount Moroto.jpg. The natural springs on the slopes of the mountain coalesce to form springs and small rivers. The World Food Program is teaching the Karimajong people how to harvest and store that water and use it to irrigate agricultural produce for household food and for income generation.
In contrast, if formed by past above-water volcanism, they are known as a seamount chain. The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge. [1] It has been observed that, "similar to those on land, the undersea mountain ranges are the loci of frequent volcanic and earthquake activity". [2]
