Which process destabilizes hillsides when permafrost thaws due to warming temperatures?

💡 Explanation

When permafrost thaws, ice within the soil melts, reducing its shear strength, which, when coupled with gravity, allows the saturated soil to flow downslope via solifluction. Therefore, solifluction from reduced strength results, rather than rebound, oxidation, or deposition, which require distinct geological mechanisms.
