Which landform results through seasonal thaw in permafrost?

💡 Explanation

Solifluction lobe formation arises due to seasonal thawing of the active layer. Frost creep causes soil to flow downhill as a viscous mass forming distinct lobes because thawed soil loses shear strength, therefore solifluction rather than other glacial forms arises.
