Which outcome accelerates when saturated soil exceeds its shear strength on moderate arctic slopes?

💡 Explanation

When saturated soil exceeds its shear strength, solifluction occurs because the active layer thaws over impermeable permafrost, causing slow downslope flow creating terraced lobes. Therefore solifluction lobe formation increases, rather than oxidation, reduced thermokarst, or weakened eolian processes, which depend on different mechanisms.
