Freeze thaw (mechanical/physical) weathering - occurs when rocks are porous (contain holes) or permeable (allows water to pass through it
Biological weathering - roots of growing plants can widen cracks in rocks. burrowing animals and resting birds on cliff faces can also cause rocks to weaken and decay.
Chemical weathering - rainwaater and seawater can be a weak acid. If a coastline is made up of rocks such as limestone or chalk, over time they can be disolved by the acid in the water
Rockfalls - bits of rock fall off the cliff face, useually due to freeze-thaw weathering
mudflow - saturated soil (soil filled with water) flows down a slope
Landslide - large blacks of rock slide downhill
