Which of the following is a type of physical weathering?
Thu Aug 15 2002 14:30:00 GMT-0400 (Eastern Daylight Time) · Physical weathering Physical weathering also called mechanical weathering or disaggregation is the class of processes that causes the disintegration of rocks without chemical change. …
Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite. When saprolite is exposed by physical erosion these concentric layers peel (spall) off as concentric shells much like the layers of a peeled onion. Within saprolite spheroidal weathering often creates rounded boulders known as corestones or woolsack of relatively unweathered rock. Spheroida…

A combination of existing fractures wicking of groundwater salt weathering and dissolution contribute to the formation. Insolation weathering and frost weathering may be valid depending on the region. As with all weathering weathered material is winnowed away by water (primarily) gravity or (minorly) wind.
These explanations include marine abrasion; wind corrosion; mechanical weathering resulting from short-term temperature variations; chemical weathering of the interior of the rock (core-softening) under a protective crust (case-hardening) followed by mechanical removal of the softened...
