← GeographyIncreased earthworm activity in loess results in which soil outcome?
A)Enhanced soil horizon intermixing✓
B)Accelerated chemical weathering rates
C)Decreased organic matter decomposition
D)Reduced soil profile macroporosity
💡 Explanation
Increased earthworm activity in loess causes enhanced soil horizon intermixing because bioturbation (earthworm burrowing) physically mixes soil layers. This homogenizes the soil profile rather than allowing distinct horizon development because it redistributes materials.
