Which downslope movement results when permafrost thaws and the active layer loses shear strength?

💡 Explanation

When permafrost thaws, the active layer becomes saturated and loses strength because the ice cementing the sediment melts, causing solifluction. Therefore, solifluction lobe formation results, rather than crevassing, volcanism, or oxbow lake formation occurring due to brittle failure, tectonic, or fluvial processes respectively.
