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 .
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.

Escarpment face of a cuesta, broken by a fault, overlooking Trenton, Cloudland Canyon State Park, and Lookout Mountain in the U.S. state of Georgia. An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations.
The Pottsville Escarpment is a resistant sandstone belt of cliffs and steep sided, narrow crested valleys in eastern Kentucky, USA. It features rock shelters, waterfalls, and natural bridges. It is also called the Cumberland Escarpment and forms the western edge of the Cumberland Plateau.
In geology and geomorphology, a hogback or hog's back is a long, narrow ridge or a series of hills with a narrow crest and steep slopes of nearly equal inclination on both flanks. Typically, the term is restricted to a ridge created by the differential erosion of outcropping , steeply dipping (greater than 30–40°), homoclinal , and typically ...
For example, the south face rises 5,000 feet (1,500 m) in just 2 horizontal miles (3.2 km). The northeast and northwest sides of the mountain exhibit similar steep relief. [ 6 ] Due to its location away from higher peaks, Mount Stuart has a topographic prominence of 5,354 feet (1,632 m), making it the sixth most prominent in the state. [ 7 ]
Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography , and as such its portrayal presents a central problem in cartographic design , and more recently geographic ...
Hachure representation of relief was standardized by the Austrian topographer Johann Georg Lehmann in 1799. [1] Hachures may be combined with other ways of representing relief, such as shades, the result being a shaded hachure map; an example of such a map is the Dufour Map of Switzerland . [ 2 ]
