← GeographyWhich outcome occurs when parent material experiences increased bioturbation?
A)Accelerated topsoil horizon formation✓
B)Decreased clay mineral weathering
C)Amplified eluviation process rates
D)Reduced organic matter stabilization
💡 Explanation
Increased bioturbation mixes organic matter and minerals, accelerating horizon blending and topsoil formation; this pedogenesis results in faster soil development because mechanical and chemical processes interact, therefore favoring topsoil's formation rather than limiting other weathering actions.
