Sheet erosion is the correct type of erosion that removes a thin layer of soil. This process occurs when water, typically from rainfall, flows over large, flat areas and gradually washes away thin layers of soil uniformly across the surface. The removal is subtle and may not be immediately noticeable, which distinguishes it from other forms of erosion like rill or gully erosion that create more pronounced channels or depressions in the land.

Understanding the dynamics of sheet erosion is crucial for land management, as it can lead to significant soil loss over time, affecting soil fertility and water retention. By managing water runoff and vegetation cover, we can help mitigate the impacts of sheet erosion and preserve valuable topsoil.
