Which risk increases when construction destabilizes a hillslope undergoing solifluction in an arctic region?

💡 Explanation

When construction destabilizes a slope with solifluction, the disruption increases the rate of soil movement causing exposure of permafrost to warmer temperatures, accelerating thawing through conduction. Therefore accelerated permafrost degradation results, rather than methane hydrate formation, albedo changes, or thermohaline shifts, dependent on subsurface geology or ocean salinity gradients.
