Which resulting ground distortion occurs when solifluction rates drastically increase on a moderate slope?

💡 Explanation

When solifluction rates increase, the saturated soil layers flow downslope due to gravity-driven creep because thawed ground loses its cohesive strength. This leads to the formation of terracettes, step-like features across the slope. Therefore, downslope terracette formation results, rather than kettle holes, polygon expansion, or subsidence sinkholes which derive from other distinct geomorphic processes.
