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

• A. Soil erosion
• B. Leaching
• C. Weathering
• D. Aggregation

Answer: (A)

Soil erosion is the movement of soil components, especially the topsoil, from one place to another, usually by wind, flowing water, or both. This process reduces soil depth and fertility and can deposit sediment in streams and rivers. Wind erosion occurs in dry, loose soils and can form dust plumes or dunes, while water erosion happens when rainfall and runoff detach and transport soil particles, creating sheet erosion, rill erosion, or gullies. Leaching is the downward movement of soluble nutrients with water, not soil particles; weathering is the breakdown of rock into smaller pieces; and aggregation refers to the clumping of soil particles without describing their transport.
