Which pedogenic effect results more rapidly when alternating extreme temperatures cause repeated volumetric change in granite?

💡 Explanation

Increased physical weathering leads to fracturing because thermal stress causes the process of thermal fracturing to break down the rock. Therefore, physical weathering increases, rather than anion exchange which requires water and mobility, or enhanced organic retention needing biota activity.
