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. sharps rear vernier sightsWebCliff Dwellings. what is it called when rock that forms beneath the Earth's surface is compressed by the rock above.
