Which risk increases significantly when freeze-thaw cycles accelerate solifluction rates on arctic construction sites?

💡 Explanation

When freeze-thaw cycles accelerate solifluction rates, slopes become unstable because the saturated active layer flows downslope over the frozen ground, causing soil creep that compromises foundations. Therefore foundation instability results, rather than methane release, rainfall erosion, or refrigerant contamination, which depends on differing conditions.
