Which term refers to the movement of rock or soil fragments?

• A. Erosion
• B. Abrasion
• C. Weathering
• D. Deposition

Answer: (A)

Erosion is the movement of rock or soil fragments from one place to another. It happens when natural forces like rivers, wind, ice, or gravity pick up material and transport it, reshaping landscapes as sediment is carried away. This distinguishes erosion from weathering, which breaks rocks down in place, and from deposition, which is the settling of material after transport. Abrasion is a specific way erosion wears surfaces down through grinding, but the overall idea of moving fragments is best described by erosion.
