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 ...
With crustal extension, a series of normal faults which occur in groups, form in close proximity and dipping in opposite directions. [4] As the crust extends it fractures in series of fault planes, some blocks sink down due to gravity, creating long linear valleys or basins also known as grabens, while the blocks remaining up or uplifted produce mountains or ranges, also known as horsts.
Upwelling intensity depends on wind strength and seasonal variability, as well as the vertical structure of the water, variations in the bottom bathymetry, and instabilities in the currents. In some areas, upwelling is a seasonal event leading to periodic bursts of productivity similar to spring blooms in coastal waters. Wind-induced upwelling ...
There are five main types of mountains: volcanic, fold, plateau, fault-block, and dome. A more detailed classification useful on a local scale predates plate tectonics and adds to these categories. [ 6 ]
An oceanic plateau is a large, relatively flat submarine region that rises well above the level of the ambient seabed. [50] While many oceanic plateaus are composed of continental crust , and often form a step interrupting the continental slope , some plateaus are undersea remnants of large igneous provinces .
Depending on either their size, other physical characteristics, or geographic location, the landforms comprising a tableland are individually referred to by a number of names including either butte, mesa, plateau, potrero, tepui, or tuya. [1] [2] A homologous landform under the sea is called either a tablemount or guyot.
Embraced by the warm, crystalline waters of the Tyrrhenian Sea, just off the west coast of Italy’s Tuscan shoreline, Isola d’Elba is Italy’s lettera d'amore to the Mediterranean sun and sea.
NASA satellite photo of typical Basin and Range topography across central Nevada. The Basin and Range Province includes much of western North America.In the United States, it is bordered on the west by the eastern fault scarp of the Sierra Nevada and spans over 500 miles (800 km) to its eastern border marked by the Wasatch Fault, the Colorado Plateau and the Rio Grande Rift.
