← GeographyWhich outcome results when acidic rainwater accelerates mineral dissolution?
A)Nutrient depletion in upper soil✓
B)Increased soil aggregate stability
C)Enhanced microbial decomposition rates
D)Reduced clay mineral weathering
💡 Explanation
Accelerated mineral dissolution by acidic rainwater causes nutrient leaching, removing essential elements from the topsoil horizons. This downward movement occurs via eluviation because soluble compounds are carried away, therefore leading to nutrient depletion rather than enhanced microbial decomposition.
