Which term describes the movement of soil components, especially topsoil, from one place to another, usually by wind or water?

• A. Weathering
• B. Sedimentation
• C. Soil Erosion
• D. Leaching

Answer: (C)

This is soil erosion. It describes the movement of soil components, especially the nutrient-rich topsoil, from one place to another primarily by wind or water. This removal reduces soil fertility and structure, can shape landforms through sheet, rill, or gully erosion, and often leads to sedimentation in waterways. Weathering is the in-place breakdown of rock to form soil and doesn’t involve moving material. Sedimentation is the deposition of eroded material after transport. Leaching is the downward movement of soluble minerals with water through the soil profile, not the lateral transport of soil particles. Understanding erosion helps explain why protecting topsoil with practices like cover crops or windbreaks is so important.
