Which failure type is accelerated as permafrost thaws?

💡 Explanation

Thermokarst lake formation accelerates because permafrost degradation causes ground subsidence via the collapse of previously ice-rich soil; this positive feedback is thermal erosion rather than altered glacial deposits that require different processes.

• Which outcome occurs when a fault line is subjected to high pore fluid pressure?
• Which consequence results when thermokarst thawing weakens Arctic slopes?
• Which consequence occurs the instant a lava dome collapses within a stratovolcano structure?
• Which outcome enhances lahar formation during tropical storms?
• Which geological shaping occurs due to ventifact formation?
• Which process causes shallow repeating earthquakes during creep?
