|escarpment (ĭ-skärp'mənt) Pronunciation Key
A steep slope or long cliff formed by erosion or by vertical movement of the Earth's crust along a fault. Escarpments separate two relatively level areas of land. The term is often used interchangeably with scarp but is more accurately associated with cliffs produced by erosional processes rather than those produced by faulting.
