PLATEAU (a See also:French See also:term, older platel, for a See also:flat piece of See also:wood, See also:metal, &c., from plat, flat)  , in See also:physical See also:geography, an elevated region of level or gently undulating See also:land-See also:surface, the See also:term being synonymous with " table-land." The most clearly defined plateaus have steep flanks in contrast with their level summits, but the term does not necessarily connote a steep ascent from the surrounding See also:country . Indeed, it is applied to such diverse forms as the high-lying plains encircled by the higher elevations of the See also:Andes, and to those of the See also:west of See also:North See also:America, which rise almost imperceptibly from the See also:low central plains . A See also:plateau may have its origin either in the upheaval of strata which preserve their See also:original See also:horizontal position during the See also:process, or in the prolonged denudation of an originally broken surface . The two forms are distinguished respectively as Plateaus of Deposition and Plateaus of Erosion .
