← GeographyWhich pedogenic outcome occurs when intense rainfall impacts bauxite deposits?
A)Surface horizons experience increased silicification
B)Relative aluminum concentration increases✓
C)Regolith clay mineral content decreases
D)Weathering shifts towards increased oxidation
💡 Explanation
Laterization occurs because intense tropical weathering causes leaching of silica; therefore, aluminum oxides/hydroxides become relatively concentrated in the B horizon, rather than silicon dominating due to feldspar or volcanic weathering processes.
