How do freezing,thawing,wetting,and drying contribute to soil creep?
A)The soil becomes much weaker when dry and frozen.
B)Gravity exerts a much stronger force when the soil is wet and thawed.
C)The soil expands and contracts,lifting particles and dropping them a slight distance downslope.
D)Eventually,these cause the soil and regolith to suddenly slide down the slope.

Question

Quizplus · Accepted Answer

Freezing and thawing cycles cause the soil to expand and contract, which can lift particles and drop them downslope, contributing to soil creep. Wetting and drying cycles can also cause expansion and contraction, further promoting soil creep. These processes do not necessarily cause sudden landslides, but can contribute to slow, gradual movement over time.
