Another way material can be moved on the coastline is through mass movement. Mass movement is the downhill movement of sediment that moves because of gravity. There are four different types of mass movement:
Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
Saturated soil (soil filled with water) flows down a slope.
Large blocks of rock slide downhill.
Saturated soil slumps down a curved surface.
