Which consequence typically results when prolonged tephra deposition buries arable land?

💡 Explanation

Tephra buries surface soil, inhibiting the pedogenesis mechanism, because it smothers the biological activity that develops soil horizons. Thus, profile formation halts; rather than enhancement, the pre-existing soil’s nutrient cycle is interrupted.

• Which outcome occurs when gradual 'longshore drift' along a coastline encounters a significant river estuary?
• Which outcome results when tephra deposition overwhelms drainage systems?
• Which outcome occurs when land experiences significant deflation?
• Which outcome results downstream when glaciers accelerate surge flow?
• Which outcome occurs when dissolved carbon dioxide concentrations increase?
• Which risk commonly develops in heavily bioturbated soil horizons?
