Which mechanism promotes fine regolith formation due to differential heating?

💡 Explanation

Thermal stress weathering causes rock disintegration because repeated expansion/contraction weakens bonds; therefore a fine regolith is generated in desert environments, rather than larger clasts via frost wedging.
