← GeographyWhich outcome accelerates when earthworm population densities increase?
A)Soil water infiltration rates increase✓
B)Chemical weathering reactions decrease
C)Clay particle aggregation decreases slowly
D)Capillary action in soil diminishes
💡 Explanation
Increased earthworm activity enhances soil aeration and drainage by bioturbation, because their burrowing creates macropores allowing faster water movement; therefore, infiltration rises rather than weathering slowing or capillary action diminishing.
