← GeographyWhich landform develops when freeze-thaw cycles and permafrost cause creeping downslope movement of saturated soil?
A)Terracettes on moderately steep slopes✓
B)Eskers in previously glaciated valleys
C)Drumlins in ground moraine areas
D)Kames near glacial retreat zones
💡 Explanation
When freeze-thaw cycles occur above permafrost, solifluction, a type of soil creep, happens because thawing saturates soil which then flows slowly downslope, forming terracettes on moderately steep slopes. Therefore terracettes are formed, rather than eskers, drumlins or kames which are formed by glacial or ice-contact processes.
