Which statement correctly describes erosion agents?

• A. Wind, water, and ice are chemical weathering agents.
• B. Wind, water, and ice are erosion agents that wear away the surface.
• C. Erosion agents only include gravity.
• D. Wind, water, and ice are erosion agents, and they can be slowed by vegetation.

Answer: (B)

Erosion agents are forces that move and transport surface material, wearing it away as they carry sediment from one place to another. Wind, moving water, and moving ice all act as erosion agents because they actively remove and shift soil, sand, and rocks, reshaping landscapes over time. For example, streams carve valleys as they carry sediment downstream, wind can sandblast exposed rock, and glaciers grind and transport rocks along their path. This movement distinguishes erosion from weathering, which only breaks rocks down in place without removing the material. So the best statement is that wind, water, and ice are erosion agents that wear away the surface by moving material. While gravity helps drive erosion and vegetation can reduce erosion, the core idea is that these forces remove and relocate surface material, which is what erosion is.
