Which downslope effect is amplified when permafrost inhibits drainage?

💡 Explanation

Solifluction accelerates because saturated soil overburdened with meltwater flows over the impermeable permafrost layer in active layer detachment and thaw settlement. Therefore, solifluction increases, rather than the glacial deposition or ice fracturing linked to other mechanisms.
