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 .
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 ...
Due to the presence of bedrock islands in the estuary area and the main river being constrained by the steep relief surrounding the deltaic region, the main channel's course has remained relatively stable, preventing the formation of deltaic lobes akin to those in the Mississippi River Delta. Consequently, the deltaic plains are concentrated in ...
About 180 million years ago, a mantle plume under southern Gondwana caused bulging of the continental crust in the area that would later become southern Africa. [2] Within 10–20 million years, rift valleys formed on either side of the central bulge and flooded to become the proto-Atlantic Ocean and proto-Indian Ocean more or less along the present southern African coastline and separating ...
The Gorda Ridge has an average depth of 3000 m, with a few locations reaching depths of 3500 m. The walls of this valley are steep, in most cases giving a vertical relief of over 1000 m. [9] The floor of the southern ridge valley has been filled in with roughly 1000 m of sediment from the continental margin, mostly delivered by turbidity ...
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 ]
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 ]
Satellite image of the Tibetan Plateau between the Himalayan mountains to the south and the Taklamakan Desert to the north. In geology and physical geography, a plateau (/ p l ə ˈ t oʊ, p l æ ˈ t oʊ, ˈ p l æ t oʊ /; French:; pl.: plateaus or plateaux), [1] [2] also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the ...
