← GeographyWhich outcome occurs when groundwater fluctuations inhibit bioturbation?
A)Increased soil horizon distinctness develops✓
B)Reduced dissolution of soluble minerals occur
C)Enhanced stabilization of hillslope regolith results
D)Decreased chemical weathering regime develops
💡 Explanation
Decreased groundwater flux prevents burrowing animals mixing soil layers through bioturbation; because the mixing action is reduced, horizon differentiation increases; therefore distinct layering becomes more apparent, rather than homogeneous soil profiles caused by organic activity.
