Increased earthworm activity in loess results in which soil outcome?

💡 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.

• Which risk increases when ephemeral desert streams overflow?
• Which process initiates hydrothermal vent formation along oceanic transform faults?
• Which risk increases when heavy rainfall saturates limestone bedrock?
• Which outcome increases as Aeolian transport weakens, causing dune crest failures?
• Which mechanism causes the formation of linear valleys when plates slide past each other at a transform boundary?
• Which outcome is accelerated when persistent katabatic winds erode exposed bedrock?
