← GeographyWhich horizon formation results when intense tropical weathering?
A)A thick, infertile oxisol forms✓
B)Gelifluction creates mass movement
C)Capillary action brings clay upward
D)Extensive peat accumulation develops
💡 Explanation
In highly weathered tropical soils, intense leaching removes silica and bases, leaving behind oxides of iron/aluminum—laterization. This pedogenesis forms an oxisol because hydrolysis and oxidation remove nutrients rather than accumulating them as in gelifluction soils.
