Which process causes increased soil horizon mixing during flood events?

💡 Explanation

Increased stream discharge induces intense bioturbation, where burrowing organisms like worms mix sediments, therefore the soil horizons become less defined, rather than remaining stable like in normal pedogenesis alone.

• Which outcome follows increased soil disturbance in grasslands?
• Which mechanism intensifies volcanic eruption explosivity when subducting slab dehydrates?
• Which risk increases when pyroclastic flows deposit substantial tephra?
• Which effect increases when an aircraft flies at high speed near a polar front influenced by the Coriolis effect?
• Which effect occurs when multiple ocean gyres become more stratified due to freshwater input from melting glaciers?
• Which mechanism is most dominant immediately inland from an oceanic-continental subduction zone?
