WebFirstly, marine processes erode and undermine the base of the cliff. Rainwater infiltrates the cliff through unconsolidated, porous material (e.g. boulder clay). This then creates a slip plane. The weight of the saturated clay causes the material to slump along the slip plane. The process is illustrated in the diagram below. WebAnswer (1 of 4): 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. Causes of slumping include earthquake shocks, tho...
