← GeographyWhich outcome occurs when freeze-thaw exacerbates eluviation during pedogenesis?
A)Nutrient enrichment of lower horizons✓
B)Accelerated weathering of bedrock material
C)Increased stabilization of the topsoil
D)Reduced likelihood of soil creep
💡 Explanation
Freeze-thaw cycles amplify eluviation, the mechanical transport of fine particles, because soil pore connectivity increases; this causes greater water and nutrient transfer to lower soil horizons, rather than topsoil retention therefore enhancing deeper layer enrichment.
