Frost wedging caused by the ice, also known as gelivation or congelifraction, occurs along the planes of weakness of rocks (the result of their tectonic past) and is at the same time combined with the fracture planes resulting from the stresses caused by sudden changes in temperature.
This phenomenon, called gelivation or cingelifraction, occurs in all types of rock and is the first step towards the formation of a soil that plant communities can grow on.
