← GeographyWhich process accelerates later pedogenesis when dense clay inhibits infiltration?
A)Capillary water table rise
B)Preferential flow pathways✓
C)Sheet flow water erosion
D)Evapotranspiration salt accumulation
💡 Explanation
Preferential flow pathways accelerate advanced pedogenesis because macropores bypass the impeding clay layer providing water and oxygen directly to deeper horizons, therefore promoting horizon differentiation, rather than allowing stagnation near the surface.
