← GeographyWhich dissolved material accumulates due to leaching within podzol soil?
A)Sesquioxides (Fe, Al oxides)✓
B)Calcium and magnesium carbonates
C)Decomposed organic matter (humus)
D)Primary silicate minerals (feldspars)
💡 Explanation
Sesquioxides accumulate because eluviation by acidic soil solution removes them from the topsoil and illuviates them lower through podzolization; therefore, they increase in the B horizon, rather than carbonates which tend to accumulate in base-rich soils.
