Which process accelerates downslope movement in periglacial regions exhibiting cirques?

💡 Explanation

When temperatures fluctuate around freezing near cirques, solifluction occurs because the active layer thaws, becoming saturated and losing shear strength, allowing slow downslope flowage over permafrost. Therefore solifluction is accelerated, rather than weathering, eolian transport, or tectonic uplift, which require different conditions.
