← GeographyWhich horizon's increased clay content results from eluviation within soil pedogenesis?
A)B horizon (subsoil) clay enrichment✓
B)O horizon (organic layer) accumulation
C)E horizon (eluviation zone) depletion
D)A horizon (topsoil) organic mixing
💡 Explanation
Clay enrichment in the B horizon is driven by its illuviation zone during pedogenesis because fine clay particles are transported downward by gravity and water, therefore, clay accumulates in B rather than being in the A, E, or O horizons.
