Which geophysical consequence results when permafrost thaws under a sloped terrain?

💡 Explanation

When permafrost thaws, the active layer above becomes saturated and unstable because the underlying frozen ground prevents drainage, leading to solifluction because gravity drives the slow downslope movement of saturated soil. Therefore increased solifluction results, rather than decreased sequestration, esker formation, or isostatic rebound which require different glaciofluvial mechanisms.
