Respuesta :

Exfoliation is a type of weathering in which curved and concentric sets of joints break away in successive layers.

What is exfoliation?

  • Exfoliation is the separation of successive thin shells, or spalls, from massive rock such as granite or basalt.
  • It is common in areas with moderate rainfall.
  • Individual sheets or plates can range in thickness from a few millimeters to a few meters.
  • Exfoliation, according to some geologists, occurs when rocks formed at depth are exposed to the bottom surface.
  • However, the fractures are frequently not parallel to the ground surface, and this is interpreted as evidence of another method of formation.

Therefore, exfoliation is a type of weathering in which curved and concentric sets of joints break away in successive layers.
