Which outcome occurs when permafrost melts underpinning a cirque?

💡 Explanation

Increased debris flow results when permafrost melts because the loss of ice cementation reduces slope stability, activating the mechanism of solifluction. Therefore, loose sediment masses slide downhill more readily rather than remaining stable crystalline structures.
