← GeographyWhich outcome occurs when increased rainfall amplifies earthworm bioturbation?
A)Enhanced soil macroporosity formation✓
B)Accelerated mineral oxidation rates
C)Reduced argillic horizon development
D)Decreased cation exchange capacity
💡 Explanation
Enhanced earthworm activity increases burrow creation through bioturbation, promoting macroporosity because earthworms physically mix the soil. Therefore, soil drainage improves, facilitating aeration, rather than inhibiting chemical reactions or development of soil horizons.
