plateau,

elevated, level or nearly level portion of the earth's surface, larger in summit area than a mountainmountain,

 and bounded on at least one side by steep slopes, occurring on land or in oceans. Some plateaus, such as the Deccan of India and the Columbia Plateau of the NW United States, are basaltic and were formed as the result of a succession of lava flows covering hundreds of thousands of square miles that built up the land surface. Others are the result of upward folding; still others have been left elevated by the erosion of adjacent lands. Plateaus, like all elevated regions, are subject to dissection by erosion, which removes greater amounts of the upland surface. Low plateaus are often agricultural regions, while high plateaus are usually fit chiefly for stock grazing. Many of the world's high plateaus are deserts. Other notable plateaus are the Colorado Plateau of the W United States, the Bolivian plateau in South America, and the plateaus of Anatolia, Arabia, Iran, and the Tibet region of China.

Plateau

 

an elevated plain with an even or undulating, slightly dissected surface and separated by clearly distinguishable scarps from the adjacent country. The following are distinguished: (1) structural plateaus, which are composed of horizontally bedded rock strata; (2) volcanic, or lava, plateaus, in which the irregularities of the former relief have been capped with lava; (3) denudation plateaus, which are uplifted denudation plains, such as peneplains and abrasion plains; and (4) mountainous plateaus, which are intermontane depressions filled with the weathering products of the surrounding mountain ranges.

a US scientific station in Eastern Antarctica, located in the interior of the continent, in the western part of the Sovetskoe Plateau. The station is on the surface of an ice sheet, 3,624 m above sea level, and 1,000 km from Kosmonavtov Sea. Plateau Station was in operation from February 1966 through January 1969. It conducted aerometeorological, glaciological, and geophysical observations and served as a base for field research in the adjacent regions.
