Which surface deformation occurs when the active layer thaws?

💡 Explanation

Solifluction generates soil lobes because freeze-thaw cycles create instability. This promotes downslope movement. The mechanism is soil creep, so soil lobes will form downslope, rather than less soil movement or stable land.
