Aerial erosion also has a role to play in the formation of coastal features such as the Bullers of Buchan in Aberdeenshire. Here weaknesses in the rock stretch to the surface above a cave, resulting in the formation of a blowhole. In Stonehaven, weathering has resulted in slumping when material saturated by rain has become too heavy and unstable to stay up.
