← GeographyWhich mass wasting process is amplified within a cirque containing thawing permafrost?
A)Solifluction due to lubricating meltwater✓
B)Rockfall from reduced slope stability
C)Creep due to gradual downslope stress
D)Debris flow initiated by heavy rainfall
💡 Explanation
When permafrost thaws, solifluction intensifies because active layer soil saturates with meltwater, reducing friction and enabling downslope viscous flow within the cirque headwall. Therefore solifluction is amplified, rather than rockfall, creep, or debris flows which require different triggering conditions related to freeze-thaw cycles or precipitation events.
