← GeographyWhich outcome results when organic matter accumulates during soil pedogenesis?
A)Enhanced cation exchange capacity✓
B)Reduced soil aggregate stability
C)Increased soil albedo globally
D)Lower overall soil infiltration rate
💡 Explanation
Enhanced cation exchange occurs because humification, a form of pedogenesis, increases the surface area and negative charge in soil colloids via organic compounds; therefore, enhanced ion retention results, rather than lower stability or albedo changes.
