Answer: C - Sheet erosion would produce an even disappearance of topsoil.

Key Takeaway: Sheet erosion occurs when soil particles flow with water that flows over land as a sheet, instead of in channels or streams. This usually happens in a particularly heavy rain, in which the impact of the drop breaks apart the soil and the clay, silt, or sand flow with the water. This type of erosion would produce a perfectly even disappearance of a given area’s topsoil.
