Which process causes downslope soil movement attributed to solifluction in alpine arctic regions?

💡 Explanation

When soil is saturated, freeze-thaw cycles cause the soil water to expand during freezing and contract during thawing, destabilizing the soil matrix, leading to gentle downslope movement via solifluction. Therefore freeze-thaw is the correct answer, rather than chemical weathering, wind desposition, or seismic effects which have distinct signatures.
