Which consequence results along coastlines when permafrost degrades?

💡 Explanation

Increased coastal erosion will occur because thawing permafrost undergoes **thermal erosion**, weakening coastal bluffs; therefore, cliffs fail rapidly rather than remaining stable due to vegetation, decreased storm severity or mangrove expansion affecting wave impact.
