Exfoliation is a form of rock weathering, also referred to as onion skin weathering. It is characterized by a layer by layer erosion of the outer surface of the rock caused by â¦ chemical changes to the composition of the minerals, by differences in temperature between the outer surface and the interior of the rock, or by the expansion and separation of the outer surfaces due to moisture absorption.
There are two main types of physical weathering: 1  Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. 2  Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.
