Which geological hazard accelerates along shorelines due to thawing permafrost beneath coastal bluffs?

💡 Explanation

When permafrost thaws due to warming temperatures, thermokarst formation occurs because the ice within the soil melts, causing ground subsidence and increased coastal erosion. Therefore subsidence results, rather than tsunamis or volcanism, which require seismic activity, or desertification which is an aridity-related phenomenon.

• Which phenomenon results when Earth's rotation causes subtropical atmospheric pressure cells to produce consistent deflection?
• Which landscape outcome results when wind-driven deflation surpasses supply?
• Which primary erosional process initially shapes the V-shaped valley that develops into an alluvial fan system?
• Which mechanism primarily controls the orientation of cirque-formed valleys within a glaciated mountain range?
• Which mechanism distributes floating plastics throughout the North Pacific Gyre?
