Which landform develops when permafrost thaw triggers solifluction?

A)Lobes on gentle slopes
B)Esker ridge formations
C)Kettle lake depressions
D)Drumlin field alignments

💡 Explanation

When thawing permafrost saturates the active layer, solifluction occurs, which is the downslope movement of soil; this creates distinct lobate landforms because the saturated soil flows very slowly, therefore creating lobes, rather than other glacial sedimentary features.
