On Arctic slopes, which consequence follows enhanced freeze-thaw weathering?

💡 Explanation

Increased freeze-thaw cycles weaken soil structure because ice lens formation causes soil particle displacement, leading to increased downslope solifluction rates; therefore, soil flows more easily, rather than experiencing stabilized vegetation or other weathering.
