Where are exfoliation domes found?
Perhaps the most famous exfoliation domes in the United States are Stone Mountain, Georgia and Enchanted Rock in the Hill Country of Texas.
Does exfoliation occurs in the Sierra Nevada mountains?
Exfoliation is the breaking and fracturing of hard rocks like granite in slabs parallel to the surface of the rock. It removes corners and edges, resulting in the familiar domes found in regions like the Sierra Nevada where lots of granitic rock is exposed.
Where is exfoliation most likely to occur?
Where is exfoliation most likely to occur? Exfoliation occurs mostly in mountain regions where intrusive igneous rock has been uplifted and exposed by erosion.
What is a good example of an exfoliation dome?
This process is called exfoliation; large rounded landforms (usually intrusive rocks) that result from this process are called exfoliation domes. Examples of exfoliation domes are Stone Mountain, Georgia, and Half Dome in Yosemite National Park.
Where does exfoliation dome form from?
Exfoliation is a form of mechanical weathering in which curved plates of rock are stripped from rock below. This results in exfoliation domes or dome-like hills and rounded boulders. Exfoliation domes occur along planes of parting called joints, which are curved more or less parallel to the surface.
What is exfoliation dome?
Definition of exfoliation dome : a large dome-shaped rock mass (as of granite) produced by exfoliation.
How is exfoliation dome formed?
A large homogeneous rock is exposed to alternate expansion and contraction of the outer layer in a rock. This is caused by temperature differences. Once the material has peeled off and rolled away a smooth dome shaped rock is left behind. It is called an exfoliation dome.

How does exfoliation dome form?
Exfoliation is a form of mechanical weathering in which curved plates of rock are stripped from rock below. This results in exfoliation domes or dome-like hills and rounded boulders. One after another these layers are spalled off resulting in rounded or dome-shaped rock forms.

What is exfoliation in geography where it is commonly found?
