A valley is an elongated low area often running between hills or mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in ...
An arête (/ ə ˈ r ɛ t / ə-RET; French:) [1] is a narrow ridge of rock that separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. [2]
Arête – Narrow ridge of rock which separates two valleys formed by glacial movement; Cirque – An amphitheatre-like valley formed by glacial erosion; Col – Lowest point on a mountain ridge between two peaks; Crevasse – A deep crack, or fracture, in an ice sheet or glacier; Corrie – An amphitheatre-like valley formed by glacial erosion ...
A rift valley near Quilotoa, Ecuador. The Ottawa-Bonnechere Graben Þingvallavatn. A rift valley is a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may ...
Map of the Great Rift Valley. The Great Rift Valley (Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 6,000 or 7,000 kilometres (4,300 mi) in total length, the definition varying between sources, that runs from the southern Turkish Hatay Province in Asia, through the Red Sea, to Mozambique in Southeast Africa.
Two Grand Canyon-size features on the far side of the moon were likely formed in about 10 minutes after an unknown object slammed into the moon 3.8 billion years ago.
U-shaped, or trough, valley: U-shaped valleys are created by mountain glaciers. When filled with ocean water so as to create an inlet, these valleys are called fjords. Arête: spiky high land between two glaciers. If the glacial action erodes through, a spillway (or col) forms
Example on a topographical map, and how it would look in the real world. Typical draw, Little Carpathians A draw, sometimes known as a re-entrant in orienteering, is a terrain feature formed by two parallel ridges or spurs with low ground in between them.
