Exfoliation
The process is called exfoliation, where outer layers of rock peel away due to pressure release as the rock is exposed at the surface. This can be caused by factors like temperature changes, erosion, or tectonic stresses, leading to the formation of large sheets of rock.
Mica is a mineral composed of thin, flexible layers. These layers allow mica to easily break into thin sheets or flakes along one direction, a property known as perfect basal cleavage.
Mica breaks into sheets due to its perfect basal cleavage, which allows it to easily split into thin, flat layers. This is a physical property that occurs because the bonds between the sheets of mica are weaker than the bonds within the sheets, causing it to break along these planes.
Mica breaks along flat sheets because it has a layered structure with weak bonds between the layers. When stress is applied, these weak bonds allow the layers to easily slide past each other, resulting in the mica breaking evenly along the planes of weakness.
This process is known as thermal stress weathering. It occurs when rocks expand and contract due to temperature changes, causing the outer layers to crack and break off. Over time, this repeated cycle of heating and cooling can lead to the disintegration and movement of rock layers.

In for form of graphite it can be broken into graphene sheets. In other forms carbon does not break into sheets.

A land slide may also be called an avalanche.
The process of ice breaking off a glacier or ice sheet is called "calving".

Joint sheeting weathering refers to the process where rock layers exfoliate or peel away due to the expansion and contraction of the rock caused by temperature changes. This weathering type is common in areas with large diurnal temperature variations. Over time, the repeated stress from this expansion and contraction can cause the rock to break along natural joints or fractures, resulting in thin layers peeling away.
The process in which layers of rock flake off a larger rock as a result of weathering is called exfoliation. This occurs due to the expansion and contraction of rock layers in response to changes in temperature, causing the outer layers to break off. Over time, repeated cycles of expansion and contraction lead to the gradual exfoliation of the rock's outer layers.
Yes, foliated metamorphic rocks tend to break along their layers or foliation planes due to the alignment of minerals during metamorphism. This can result in the rock breaking into thin sheets along its outer edges.
