Foliation in rocks refers to the process being split into thin sheets. It is caused by intense pressure that shapes rocks to align in particular directions.
An exfoliation dome is a geological formation characterized by a large, rounded rock mass that has undergone exfoliation, a process where layers of rock peel away from the surface due to pressure release and weathering. This typically occurs in granite or other coarse-grained rocks when overlying material is removed through erosion, leading to a reduction in pressure. As the rock expands, it fractures in thin, curved sheets, creating the dome shape. Notable examples include Half Dome in Yosemite National Park.
Probably not very much, igneous rocks are caused through the cooling of magma or larva and are very common on earth. Granite and Basalt are examples of igneous rocks.
Wear on the rock, like for example in a river there are a lot of smooth pebbles because the water flowing by smooths the surface

when rocks expand with pressure
Exfoliation.
Freeze-thaw cycling will cause exfoliation of larger rocks. Particularly if they are somewhat crystalline. This is because the main mass of the rock will retain its temperature better than an exposed corner. Thus stress caused by thermal expansion will develop, and the exposed corner will break off.

Exfoliation. This process occurs due to pressure release when overlying rocks are eroded and removed.
Exfoliation.
Three processes that mechanically weather rocks are frost wedging (freeze-thaw cycles), exfoliation (physical weathering due to pressure release), and abrasion (erosion caused by frictional forces).
