← GeographyWhich process impacts mineral transformation during advanced pedogenesis?
A)Cheluviation facilitated by organic acids✓
B)Mechanical exfoliation by freeze-thaw cycles
C)Preferential dissolution of calcite minerals
D)Oxidation of iron under arid conditions
💡 Explanation
Cheluviation mobilizes metal ions during pedogenesis, because organic acids form complexes that enhance mineral weathering; therefore, mineral transformation shifts toward stable secondary phases, rather than remaining in parent material conditions.
