The peeling off the plates from parent rock due to differential expansion and contraction of minerals as a result of temperature changes is called Exfoliation. It is a process in which large flat or curved sheets of rock fracture and are detached from the outcrop due to pressure release. It mostly occurs when the temperature of rocks changes rapidly that can expand or crack the rocks.
