Which process dominates within a high-altitude cirque basin experiencing repeated freeze-thaw cycles?

💡 Explanation

With repeated freeze-thaw cycles, cryoturbation disrupts soil structure because ice lens formation expands and contracts sediments, which reduces cohesion, enhancing solifluction. Therefore cryoturbation is the prevailing process, rather than karstification, aeolian deposition, or hydraulic action which need different environmental preconditions.
