← GeographyWhich soil consequence results when increased water runoff accelerates weathering?
A)Horizon A nutrient depletion✓
B)Accelerated clay mineral formation
C)Increased cation exchange capacity
D)Enhanced soil profile aggregation
💡 Explanation
Horizon A nutrient depletion occurs because overland flow intensifies preferential weathering by eluviation. This strips the uppermost soil layer, therefore, there's nutrient loss from the decreased residence time of dissolved minerals, rather than mineral proliferation.
