Which geomorphic outcome occurs because continuous permafrost sharply degrades?

💡 Explanation

Thermokarst occurs due to thawing permafrost; the active layer deepens, causing ground subsidence called thaw settlement, therefore creating depressions and irregular terrain, forming patterned ground, rather than forming eskers/drumlins because permafrost is generally far from active glaciers.
