← GeographyWhich process accelerates soil horizon homogenization through biological activity?
A)Enhanced pedogenesis through vertical bioturbation✓
B)Increased water table capillary action
C)Elevated argillification of clay minerals
D)Accelerated chemical weathering by acid rain
💡 Explanation
Enhanced pedogenesis accelerates horizon homogenization via vertical bioturbation displacing materials; because organisms mix soil layers, therefore horizons blend uniformly rather than showing distinct stratification due to illuviation’s differential particle accumulation.
