As overlying surface material is eroded, some pressure on underlying rocks is removed. This decrease in pressure on the body of rock allows the rock to expand. Sheets of rock may peel away from the main body of rock.

What process forms exfoliation domes?

The formation of an exfoliation dome begins with sheeting, when large masses of igneous rock, particularly, granite, are exposed by erosion, concentric slabs begin to break loose, this process occurs in part because of the great reduction in pressure when the overlying rock is eroded away, a process called unloading, and accompanying this unloading, the outer layers expand more than the rock below and thus separate from the rock body. Continued weathering eventually causes the slabs to separate and spall off, creating exfoliation domes.

The process by which outer layers of rock are stripped away is called?

The process of outer rock layers being stripped away is called erosion. Erosion can be caused by natural forces like water, wind, and ice, as well as human activities like mining and construction.


Is exfoliation physical or chemical weathering?

Exfoliation is a form of physical weathering where outer layers of rock gradually peel away due to pressure release. This process is often influenced by factors like temperature changes and erosion, leading to the expansion and consequent detachment of rock layers.

What is exfoliation and what types of rock is it most common in?

Exfoliation is a geological process in which layers of rock peel away from a larger mass, often due to the release of pressure from overlying materials or temperature changes. This process is most common in igneous rocks, particularly granite, where the outer layers expand and contract more than the inner layers, leading to the formation of thin, flake-like sheets. Exfoliation is commonly observed in mountainous regions where erosion has removed the overburden.

What is the weathering process which led to the formation of tors?

The weathering process involved in the formation of tors is exfoliation (onion skin weathering). Exfoliation can be mechanical or chemical. Mechanically, exfoliation may be a result of the different expansion rates between exterior and interior layers. Chemically, the exterior of the rock can be chemically altered to minerals of higher volume, causing it to slough off from the rock to which it was formerly attached.
