Scientific definitions for pediment

pediment
[ pĕdə-mənt ]

A broad, gently sloping rock surface at the base of a steeper slope such as a mountain, often covered with alluvium. Pediments are formed through the exposure of bedrock by erosional processes, such as the flow of water. Pediments are usually found in arid regions where there is little vegetation to hold the overlying soil.
