← GeographyWhich outcome occurs when heavy rainfall saturates tropical laterite soil?
A)Silica is leached, increasing iron✓
B)Organic matter accumulates rapidly at surface
C)Cation exchange capacity steadily increases
D)Calcium carbonate precipitates near surface
💡 Explanation
Saturation leads to intense laterization via leaching, where high rainfall removes mobile silica, because iron and aluminum oxides are less soluble and concentrated therefore, soil become enriched in iron and aluminum rather than accumulating organic surface matter.
