Which process is initiated at high elevations following glacial retreat from a cirque basin that exposes fractured bedrock?

💡 Explanation

When formerly glaciated cirque basins exposes steep, fractured bedrock, permafrost thaw and saturation cause solifluction because freeze-thaw cycles mobilize the saturated soil downslope, forming solifluction lobes. Therefore lobe development results, rather than exfoliation, karst, or loess which require differing geological processes or environments.
