Differential weathering
Appearance
Differential weathering is the difference in degree of discoloration, disintegration, etc., of rocks of different kinds exposed to the same environment.
Differential weathering occurs when some parts of a rock weathers at different rates than others. The quickly weathered material cannot support a steep slope and so it does not form cliffs. It is a type of Chemical weathering and it is formed in two different ways. This is a common rock characteristic that is studied in Earth Science. [1]
