Which landscape outcome results when permafrost prevents drainage, causing soil saturation?

💡 Explanation

The formation of lobes on gentle slopes occurs because solifluction involves saturated soil flowing downslope over impermeable permafrost. This is the result of water accumulation, therefore lobes form due to soil creep rather than other glacial features.
