Which effect accelerates soil creep downslope where permafrost melts?

💡 Explanation

An increased rate of solifluction occurs because thawing permafrost destabilizes soil; this allows gravity-driven creep via soil water lubrication processes, therefore increasing the downslope movement of water-saturated soil rather than sedimentation or reduced water infiltration.

• Which outcome commonly results from increased pore pressure?
• Which risk increases when a river's delta disperses into shallow coastal lakes?
• Which risk escalates when ephemeral stream discharge exceeds capacity on arid-region alluvial fans?
• Which risk increases when bentonite clay along faults hydrates?
• Which mechanism drives the formation of elongated basins along oceanic transform faults?
• Which outcome results as increased pore water pressure impacts fault mechanics during subduction?
