When a mass of rock is exposed by weathering and by removal of the overlying rock there is a decrease in the confining pressure on the rock, and a slight expansion of the rock volume. This unloading promotes cracking of the rock – known as exfoliation - and the development of cracks leads to other kinds of weathering.
