← GeographyWhich weathering-driven outcome results on basaltic rock in humid Icelandic environments?
A)Formation of thick Andosol horizons✓
B)Deposition of expansive laterite soils
C)Development of siliceous hardpans
D)Accumulation of coarse arkose sediment
💡 Explanation
Andosols form because intensive chemical weathering of volcanic ash releases aluminum and silica, which then combine with organic matter. Therefore, Andosols develop rather than laterites, which require prolonged intense weathering under tropical climatic conditions.
