← GeographyWhich landscape feature develops when saturated soil creeps downslope due to freeze-thaw cycles?
A)Terracettes across hillsides✓
B)Esker ridges parallel to stream flow
C)Kettle lakes within glacial till
D)Drumlin fields of elongated mounds
💡 Explanation
When soil saturates and undergoes freeze-thaw cycles, solifluction occurs because the water expands upon freezing, weakening the soil structure and causing downslope creep under gravity. Therefore terracettes form on hillsides, rather than eskers, kettle lakes, or drumlins which originate from glacial meltwater or ice deposition.
