What forms of mechanical and chemical weathering would be most common in the desert?

In deserts, mechanical weathering is primarily driven by temperature fluctuations, leading to thermal expansion and contraction that can crack rocks. Additionally, wind erosion plays a significant role, as strong winds can carry sand that abrasively wears down rock surfaces. Chemical weathering is less common but can occur through processes like oxidation and hydrolysis, particularly where occasional rainfall allows for chemical reactions. However, the extreme aridity limits the extent of chemical weathering compared to more humid environments.
