Which outcome occurs during repeated freezing and thawing in early terrace farming?

💡 Explanation

Increased soil erosion (solifluction) occurs, because freeze-thaw cycles cause the soil's saturated surface layer to flow downslope along an impermeable layer. Therefore, soil is displaced downslope, rather than the enhanced crop yield some seek through cryoturbation.
