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 ...
The three largest plateaus, the Caribbean, Ontong Java, and Mid-Pacific Mountains, are located on thermal swells. Other oceanic plateaus, however, are made of rifted continental crust, for example the Falkland Plateau , Lord Howe Rise , and parts of Kerguelen , Seychelles , and Arctic ridges. [ 3 ]
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
The deeper levels of the plateau have been exposed on its margins at the North American and South American plates. The volcanism took place between 139 and 69 million years ago , with the majority of activity appearing to lie between 95 and 88 Ma. The plateau volume has been estimated as on the order of 4 million km 3 (0.96
The Shatsky Rise is Earth's third largest oceanic plateau, [1] (after Ontong Java and Kerguelen) located in the north-west Pacific Ocean 1,500 km (930 mi) east of Japan.It is one of a series of Pacific Cretaceous large igneous provinces (LIPs) together with Hess Rise, Magellan Rise, and Ontong Java-Manihiki-Hikurangi.

The Pajarito Plateau in New Mexico, United States is an example of a volcanic plateau. A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava ...
The Broken Ridge or Broken Plateau is an oceanic plateau in the south-eastern Indian Ocean. The Broken Ridge once formed a large igneous province (LIP) together with the Kerguelen Plateau . When Australia and Antarctica started to separate, the Broken Ridge and the Kerguelen Plateau got separated by the Southeast Indian Ridge . [ 1 ]
The lowest surface temperature ever measured on the surface of the Earth (−93.2 °C (−135.8 °F)) was recorded by satellite on August 10, 2010, between Dome Argus and Dome Fuji. [6] Analysis of satellite data and atmospheric models shows that Ridge A , which is located 144 km (89 mi) southeast of Dome A, is potentially an even better ...
