Which process causes the formation of stacked terracettes when soil erosion decreases?

💡 Explanation

Terracettes form via differential deposition; smaller particles settle onto flat steps which larger particules remain upslope, because slope decreases reduce transport capacity for sediment, resulting in layered accumulations rather than uniform erosion.
