← GeographyWhich pedogenic outcome is boosted when freeze-thaw cycles weather granite?
A)Accelerated clay mineral formation✓
B)Increased soil organic matter
C)Decreased soil profile depth
D)Enhanced soil compaction rates
💡 Explanation
Increased surface area promotes chemical weathering because frost-wedging increases the rate of mineral dissolution; producing clay minerals during pedogenesis, therefore more clay, rather than influencing OM, depth, or soil density directly.
