Which outcome occurs when a deep soil layer experiences decreased activity of worms?

💡 Explanation

Reduced worm activity lowers bioturbation, resulting in less soil mixing and weaker soil structures, because the worms mix organic matter and minerals promoting aggregation; therefore, aggregate formation decreases, rather than increased nutrient cycling, which also involves weathering.

• Which outcome results when earthworm limitations suppress bioturbation?
• Which effect amplifies surface temperature differences influencing jet stream behavior during El Niño events?
• Which feedback results from a disruption to Hadley cells?
• Which mineral precipitation governs speleothem (cave formation) growth rates?
• Which erosional consequence results when glacial retreat accelerates within a fjord environment containing submerged bedrock ledges?
• Which risk significantly increases when coastal upwelling stalls?
