What is it called when rocks in sections parallel to the surface of the rock?
Exfoliation
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.
What is the process of exfoliation?
Exfoliation is a form of rock weathering, also referred to as onion skin weathering. It is characterized by a layer by layer erosion of the outer surface of the rock caused by chemical changes to the composition of the minerals, by differences in temperature between the outer surface and the interior of the rock, or by the expansion and separation of the outer surfaces due to moisture absorption.
What are the effects of exfoliation of rocks?
when rocks expand with pressure
How do spheroidal boulders form?
From exfoliation or other forms of weathering.

How do you use fracture in a sentence?
If you fall from the roof, you may fracture your skull. My dad went rollerskating and came home with a fracture in his left leg. On a mountainside, granite can fracture into blocks in a process called exfoliation.
What is exfoliation in dentistry?
Exfoliation is the natural process of the loss of primary ("baby") teeth.
What is a sentences for exfoliation?
Regular deep-cleansing and exfoliation should be part of your beauty routine.

What is the differences between physical weathering and chemical weathering of granite?
Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release. Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.
Which type of rock occurs when magma cools and hardens beneath the surface?
Granite is one common example.
Is granite everywhere?
No. It only occurs in areas of continental crust and is only present at the surface in a small percentage of that.
How do you spell exfoiliation?
Exfoliation.
What is the responsible for the formation of exfoliation domes?
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.
