Granite forms plutonsof igneous rock several kilometers below the surface as magmaslowly cools and crystallizes. The granite is under great overhead pressure.
Then, granite is uplifted to the surface during a mountain-building event. During the mountain building process, the overlying rock iseroded as the granite is uplifted, and the pressure on the granite reduced. The granite expands and forms fractures or sheet joints parallel to the surface. The granite then erodes in concentric layers (similar to how an onion peels) forming rounded masses called exfoliationdomes.

What process uses exfoleation domes?
Exfoliation domes are geological features formed by the repeated expansion and contraction of rocks due to temperature changes. This process, known as thermal cycling, causes the outer layers of rocks to peel away in dome-like structures.
What is the geological significance of salt domes in the formation of underground structures?
Salt domes are important in the formation of underground structures because they can create traps for oil and gas deposits. The salt domes can deform and create pathways for hydrocarbons to migrate and accumulate, making them valuable targets for exploration and production. Additionally, salt domes can also influence the stability and behavior of surrounding rocks, impacting the overall geology of an area.
Exfoliated domes are made out of what type of rock?
Exfoliated domes are typically made out of granite, a type of igneous rock. This rock type is resilient and can withstand the process of exfoliation, which involves the outer layers of the rock peeling away due to pressure release.
What is associated with the formation of salt domes?
Salt domes are formed by the upward movement of salt deposits due to their density relative to surrounding rocks. This creates structures that can trap oil and gas deposits, making salt domes important targets for oil and gas exploration. Additionally, salt domes can sometimes cause geological disturbances like earthquakes and land subsidence.
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.
Does forest wedging form exfoliation domes?
No, forest wedging does not directly form exfoliation domes. Exfoliation domes are typically formed due to variations in temperature causing expansion and contraction of rocks, leading to concentric slabs peeling off the rock surface. Forest wedging, on the other hand, refers to the action of tree roots widening existing joints or cracks in rocks.
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.
