Which outcome occurs when freeze-thaw cycles induce solifluction on a hillslope supporting pipeline infrastructure?

💡 Explanation

When freeze-thaw cycles promote solifluction, saturated soil undergoes creep downslope because ice lenses form parallel to the surface, weakening soil strength until it flows when thawed, inducing lateral pressure. Therefore pipeline buckling results from soil creep, rather than leakage, insulation loss, or emissions, requiring permafrost or specific chemical compositions.
