← GeographyWhich mineral depletion occurs during podzolization due to eluviation?
A)Iron and aluminum oxides✓
B)Calcium and magnesium carbonates
C)Potassium and sodium feldspars
D)Quartz and clay minerals
💡 Explanation
In podzolization, acidic soil promotes leaching, thus cheluviation removes iron and aluminum oxides because their solubility increases at lower pH levels; therefore, an A horizon becomes depleted, rather than enriching in calcites and silicates.
