Question

Describe the process that leads to exfoliation.

Answer 1

Exfoliation.


 Exfoliation is the term used to describe the peeling away of sheets of rock millimeters to meters in thickness from a rock's surface due a range of physical and chemical processes during exhumation and weathering . Exfoliation can occur due to several processes.

Answer 2

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.
