Which pedological effect strengthens topsoil development via bioturbation?

💡 Explanation

Topsoil structure improves via bioturbation by aerating and mixing soil. Since macrofauna move materials, this causes greater porosity; therefore aeration improves rather than decreasing erosion rather than hindering weathering progression alone.

• Which outcome occurs when earthworm populations facilitate bioturbation in topsoil?
• Which risk increases in karst regions when concentrated animal feeding operations (CAFOs) contaminate groundwater?
• Which risk increases when rapid snowmelt saturates covered karst bedrock?
• Which consequence results when isostatic rebound lags erosion in island archipelagos?
• Which mechanism sorts sediment in alluvial placer deposits?
• Which outcome occurs when parent rock weathers during pedogenesis?
