A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Comments.
Waves shape a coast when they deposit sediment, which can form beaches, spits and barrier beaches. Deposition occurs when the waves slow down, causing the water to drop the sediment. This process is similar to the deposition that occurs in a river.
