A dissected plateau is a plateau area that has been severely eroded such that the relief is sharp. Such an area may be referred to as mountainous, but dissected plateaus are distinguishable from orogenic mountain belts by the lack of folding , metamorphism , extensive faulting , or magmatic activity that accompanies orogeny .
Other examples include the Brecon Beacons, Wenlock Edge, the Chilterns, the North and South Downs and the Greensand Ridge of Kent and Surrey In continental Europe, the Swabian Alb offers particularly good views of cuestas in Jurassic rock. In France, the term for a cuesta is the same as for a coastline: côte.
A bornhardt (/ ˈ b ɔːr n ˈ h ɑːr t /) is a dome-shaped, steep-sided, bald rock outcropping at least 30 metres (100 ft) in height and several hundred metres in width. [1] They are named after Wilhelm Bornhardt (1864–1946), a German geologist and explorer of German East Africa, who first described the feature. [2] [3]
Dissected plateau – Plateaus area that has been severely eroded so that the relief is sharp; List of inselbergs; Mesa – Elevated area of land with a flat top and sides, usually much wider than buttes; Mogote – Steep-sided residual hill of limestone, marble, or dolomite on a flat plain; Sky island – Geographic or environmental feature
A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km (3 mi), from canyon floor to canyon rim, as with the Great Bahama Canyon. [1]
The cliffs are noted as a textbook example of a basaltic flow with well defined joints and hexagonal columns. They were named after a band of Eastern Shoshone known as Tukuaduka ( sheep eaters ). Many of the exposed cliffs are located along a steep inaccessible canyon cut by the Gardner near Bunsen Peak , but some of the cliffs located just off ...
For example, in the case of surface models produces using the lidar technology, one can have several surfaces – starting from the top of the canopy to the actual solid earth. The difference between the two surface models can then be used to derive volumetric measures (height of trees etc.).
Less strictly, a very broad, flat-topped, usually isolated hill or mountain of moderate height bounded on at least one side by a steep cliff or slope and representing an erosion remnant also have been called mesas. [3] In the English-language geomorphic and geologic literature, other terms for mesa have also been used. [1]
