Which risk escalates on steep slopes in Arctic regions undergoing active solifluction?

💡 Explanation

When active solifluction occurs, the saturated active layer flows downslope because freeze-thaw cycles weaken soil cohesion, enhancing thaw due to disturbance of the insulating organic layer. Therefore permafrost thaw intensifies, rather than fires, deposition, or seismicity which require different environmental drivers.
