Which outcome follows increased precipitation on granite bedrock?

A)Greater chemical weathering and spheroidal weathering
B)Reduced regolith thickness and nutrient availability
C)Accelerated mechanical creep and slope instability
D)Suppressed oxidation reactions and soil darkening

💡 Explanation

Enhanced precipitation triggers greater chemical weathering of granite via hydrolysis. Hydration of feldspars causes expansion, leading to spheroidal weathering because this form of weathering acts along corners; therefore, spherical shapes result rather than angular breakage caused by frost wedging.
