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.

Which type of weathering produces an exfoliation dome?
In some case chemical weathering can cause this (where new crystals form from old ones but where the volume of the new crystals is not the same as the original). In other cases the weathering process is temperature driven by water entering the porous layer of a weathering rock and freezing. This can split the rock parallel to the surface, giving it exfoliation layers. Some texts also imply that exfoliation domes are produced by by removal of vertical pressure relieving paleo stresses in the rock, this however would not be a weathering process.
How do spheroidal boulders form?
From exfoliation or other forms of weathering.
The process by which outer layers of rock are stripped away is called?
exfoliation
What is it called when rocks in sections parallel to the surface of the rock?
Exfoliation
Which process forms a zygote?
The process that forms a zygote is called fertilization.
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.
