Which effect accelerates topsoil creep resulting from permafrost thaw in Arctic regions?

💡 Explanation

When permafrost thaws, increase in ground temperature variance amplifies solifluction because it increases freeze-thaw cycles, mobilizing the saturated topsoil layer downhill. Therefore enhanced creep, rather than inhibition via root density, results. Reduced lichen or snow are lesser related effects.
