Exfoliation is a process involving the weathering of rocks. A sudden change in temperature may cause cracks and fissures in the rocks. As water percolates into these fissures, chemical weathering takes place. The sudden expansion and contraction of rocks results in the peeling off of the outer layers of the rocks.
