Which surface deformation commonly results from seasonal solifluction in subarctic tundra caused by melting permafrost?

💡 Explanation

When permafrost thaws in summer in tundra, solifluction occurs as the active soil layer becomes saturated and flows slowly downslope due to gravity, forming terracettes because this slow creep results in step-like formations. Therefore terracettes form, rather than glacial features like eskers, drumlins or kames which involve ice deposition.
