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.

• Which mechanism causes liquefaction of soil during an earthquake in a saturated sandy deposit?
• Which outcome is directly caused by increased meander cutoff along entrenched river streams?
• Which effect does increased atmospheric carbon dioxide exert via radiative forcing on permafrost regions?
• Which process regulates salinity in closed-basin lakes under high evaporation rates when inflow halts?
• Which mechanism distributes floating plastics throughout the North Pacific Gyre?
• Which resulting ground feature indicates intense solifluction due to thawing permafrost on gentle alpine slopes?
