← GeographyWhich outcome results when significant silicate weathering occurs in humid tropical soils?
A)Increased aluminum and iron residual accumulation✓
B)Enhanced calcium carbonate horizon formation
C)Formation of cryosols and permafrost
D)Reduced rate of nutrient uptake
💡 Explanation
Laterization occurs because intense chemical weathering, specifically leaching, removes silica and alkaline earth metals, therefore concentrating insoluble iron and aluminum oxides in the upper soil horizons, rather than building carbonate layers.
