When saprolite is exposed by physical erosion, these concentric layers peel (spall) off as concentric shells much like the layers of a peeled onion. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion. Chemical weathering involves a chemical change in at least some of the minerals within a rock. first two years of college and save thousands off your degree. landforms; class-11; Share It On Facebook Twitter Email. In physical weathering, also known as mechanical weathering or disintegration, physical stresses combine to break rock apart. dissolves limestone and other rocks.
