← GeographyWhich outcome results when intense rainfall causes excess percolation?
A)Nutrient depletion in upper soil✓
B)Increased organic matter accumulation
C)Enhanced clay mineral formation
D)Reduced soil profile development
💡 Explanation
Nutrient depletion occurs because leaching removes soluble organic matter and minerals from the A horizon, therefore soil fertility declines rather than accumulates, due to the percolation induced by rainfall carrying away chemicals.
