Which outcome results when intense freeze-thaw weathering affects granitic bedrock in high-alpine regions?

A)Increased rates of soil creep.
B)Accelerated regolith horizon pedogenesis.
C)Reduced cation exchange capacity.
D)Decreased availability soil phosphorus.

💡 Explanation

Regolith horizon pedogenesis accelerates because freeze-thaw cycles mechanically weather granite into smaller particles, thereby increasing surface area available for chemical reactions during soil formation. This yields faster soil development rather than only creep and erosion, due to cryoturbation.
