Answer Details
Exfoliation and rock disintegration are weathering processes that are mainly found in desert regions.
Exfoliation is a process in which layers of rock gradually peel away from the surface of a rock formation due to changes in temperature. During the day, the rock surface can get very hot, expanding and contracting as temperatures change. At night, temperatures can drop rapidly, causing the rock to contract. Over time, this expansion and contraction can cause the outer layers of rock to break off.
Rock disintegration is a process in which rocks break apart due to a variety of factors, including temperature changes, freeze-thaw cycles, and chemical weathering. In desert regions, the combination of high temperatures during the day and low temperatures at night, along with the lack of vegetation to hold the soil and rocks together, can make rock disintegration a particularly prominent weathering process.
In contrast, tundra regions have very cold temperatures that can cause frost weathering, which breaks apart rocks due to the expansion of water when it freezes. Savannah and Mediterranean regions have more vegetation cover, which can help hold soil and rocks together, reducing the prevalence of exfoliation and rock disintegration.
