← GeographyWhich process accelerates surface soil development due to biogenic mixing?
A)Enhanced horizon differentiation✓
B)Accelerated downward solute transport
C)Increased clay mineral weathering
D)Reduced organic matter decomposition
💡 Explanation
Increased bioturbation by soil organisms causes enhanced horizon differentiation, because mixing intensifies weathering and homogenization. Bioturbation overcomes limitations, therefore promoting stratification rather than hindering it; other options do not describe bioturbation influence.
