← GeographyWhich outcome occurs when freeze-thaw cycles induce solifluction on steep Arctic slopes?
A)Formation of lobate, soil-covered terraces✓
B)Increased albedo due to exposed bedrock
C)Decreased permafrost thaw rate
D)Establishment of dense, coniferous forests
💡 Explanation
When freeze-thaw cycles saturate soil on steep slopes, solifluction occurs because ice crystal formation reduces soil cohesion, causing downslope movement of waterlogged soil. Therefore formation of lobate terraces results, rather than albedo increase, decreased thaw rate, or forest establishment which require contrasting climate conditions.
