Which gradient develops during advanced stages of podzolization?

💡 Explanation

Downward iron and aluminum oxide enrichment happens because pronounced leaching (eluviation) creates an acidic environment as part of pedogenesis concentrating these compounds over time. Therefore these oxides accumulate in the lower horizons rather than the upper horizons.
