A physical weathering process in which concentric layers of rock are removed from an outcrop.
A weathering process by which concentric shells, slabs, sheets, or flakes are successively broken loose and stripped away from a rock mass.
physical weathering process in which sheets of rock are fractured and detached from an outcrop.
The process by which an outcrop of rock splits apart into onion-like sheets along joints that lie parallel to the ground surface.
Surface deterioration caused by the expansion and contraction of trapped moisture or salts, other chemical action or weathering.
The process by which concentric scales, plates, or shells of rock are successively spalled or stripped from bare surfaces of a large rock mass. It's caused by physical or chemical forces producing differential stresses within the rock.
the act of disintegration by freeze expansion
Peeling or scaling of stone surfaces caused by chemical or physical weathering.
Physical weathering or chemical action creating a peeling off of some surface stone or masonry. Moisture freezing in surface cracks causes expansion, creating exfoliation.
Exfoliation in geology is a weathering process, mainly caused by freeze-thaw cycles.
