← GeographyWhich horizon development occurs when regolith weathering increases?
A)Increased clay mineral formation✓
B)Reduced soil organic material
C)Cementation with calcium carbonate
D)Decreased oxidation of iron
💡 Explanation
More weathering leads to increased hydrolysis and thus clay mineral formation via chemical alteration, because the regolith becomes more chemically active; therefore, horizon development includes clay accumulation rather than decreased organic content under drier conditions.
