Which term describes the process that causes rocks to be broken down into smaller particles?

• A. Water Tower
• B. Weed
• C. Windbreak
• D. Weathering

Answer: (D)

Weathering is the process that breaks rocks into smaller particles at or near the surface. It happens in place, without moving the material away, through physical actions like freeze–thaw cycles and thermal expansion, chemical actions such as reactions with acids or oxygen, and biological activity from plant roots or organisms. Over time, weathering creates soil and shapes landscapes by turning hard rock into smaller grains. This is different from erosion, which involves the transport of those particles elsewhere by wind, water, or ice. The other options aren’t processes that break down rocks: a water tower is a storage structure, a weed is a plant, and a windbreak is a barrier to reduce wind.
