plants and crops is decreased. [2] Agents responsible for soil erosion are the same as agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion because water is abundant and has tremendous power. The wind is also a leading cause of soil erosion as it can pick up soil and blow it far away.احصل على السعر
