Definition of pediplain. : an extensive geological pediment or a plain resulting from the coalescence of two or more pediments.

A pediplain is a relatively flat rock surface formed by joining several pediments. Pediments are generally found in arid and semi-arid areas and may have a thin veneer of sediments. It may be said that pediplain may be the last stage of landform evolution, and …

Pediplain. In geology and geomorphology a pediplain (from the Latin pes, genitive case pedis, meaning "foot") is an extensive plain formed by the coalescence of pediments. The processes through which pediplains forms is known as pediplanation.

28/06/2018 · A pediplain is an extensive flat terrain formed by the coalescence of pediments. The term is used in geology and geomophorlogy, and it is derived from the Latin words p es , which means "genitive case," and pedis, which means "foot."

pediplain, broad, relatively flat rock surface formed by the joining of several pediments. (See pediment.) Pediplains are usually formed in arid or semi-arid climates and may have a thin veneer of sediments. It is postulated that the pediplain may be the last stage of landform evolution, the final result of the processes of erosion.

07/04/2016 · Rather than a top-down origin, a pediplain is assumed to have formed by the lateral cutting back of a cliff or scarp so that a steep slope becomes progressively gentler. The origin proposed for an etchplain is by deep weathering (common in the humid tropics to depths of a hundred meters or more), followed by a gradual flushing away of the weathered material.

nom féminin. (anglais pediplain, de pediment, et plain, plaine) Vaste surface plane, parfois hérissée de reliefs résiduels et résultant de la coalescence de pédiments.

Peneplain Geography. Rivers, glaciers, and winds break off and carry away rock fragments from mountain and plateau surfaces. As a result, these landforms, mountains, and plateaus are gradually lowered, and their rough surfaces smoothed out to form nearly flat plains. PENEPLAINS are the name given to these plains.
