Which outcome occurs in Arctic soils featuring construction when freeze-thaw cycles are amplified?

💡 Explanation

Construction in Arctic permafrost alters soil thermal properties. This causes amplified freeze-thaw, intensifying solifluction because unfrozen soil layers above impede drainage, therefore mass soil movement increases faster rather than bedrock weathering, ice ablation, or salinity decreases.
