Which geological outcome primarily causes terracing in periglacial environments exhibiting solifluction?

💡 Explanation

When freeze-thaw cycles are present, sediment sorting occurs because finer materials migrate upward due to ice crystal formation, leading to terrace formation from solifluction’s downslope movement over impermeable surfaces. Therefore cyclic sediment sorting results, rather than weathering, uplift, or erosion each requires varying conditions.
