Which outcome occurs when repeated freeze-thaw cycles saturate high-latitude silty soils on a moderate slope?

💡 Explanation

When saturated silty soils undergo freeze-thaw, solifluction occurs because the pore water expands during freezing, weakening the soil and allowing it to flow downslope. Therefore terracettes are created by solifluction lobes, rather than kettle lakes, drumlins, or eskers which are associated with broader glacial processes.
