← GeographyWhich outcome occurs when substantial fluvial sediment deposition continually buries older soils?
A)Enhanced leaching reduces clay formation
B)Limited aeration slows pedogenesis✓
C)Accelerated mineral dissolution yields nutrients
D)Reduced weathering stabilizes soil structure
💡 Explanation
Limited aeration increasingly restricts pedogenesis, inhibiting microbial activity and horizon development, because oxygen availability for decomposition is drastically reduced. Therefore, soil formation remains immature, rather than forming developed horizons under sustained weathering conditions.
