← GeographyWhich outcome occurs involving mechanical weathering when freeze-thaw cycles erode slopes?
A)Increased talus slope deposition✓
B)Enhanced soil horizon formation
C)Stabilisation of sediment layers
D)Decreased slope angle failure risk
💡 Explanation
Increased talus slope deposition results because repeated freezing and thawing causes frost wedging, a form of mechanical weathering that fractures the rock extensively; therefore, loosened material accumulates at the slope's base rather than soil formation, sediment stabilization, or reduced failure risk.
