← GeographyWhich phenomenon results when intense rainfall accelerates pedogenesis in tropical watersheds?
A)Increased soil horizon eluviation✓
B)Reduced cation exchange capacity
C)Decreased microbial nutrient cycling
D)Stabilized soil aggregate formation
💡 Explanation
Accelerated pedogenesis causes increased soil horizon eluviation, which is the removal of clay, organic matter, and oxides due to downward water movement, because heavy rainfall intensity increases the soil infiltration exceeding its absorptive ability; therefore soluble minerals leach faster through the watershed, rather than retaining in the original profile location.
