Briefly explain weathering and erosion and one common misconception about it.

# Weathering and Erosion **Weathering** is the breaking down of rocks into smaller pieces where they sit. This happens through physical processes (like freeze-thaw cycles or tree roots), chemical processes (like acid rain dissolving rock), or biological activity. The rock fragments stay in place. **Erosion** is the transportation of those weathered materials to new locations by wind, water, ice, or gravity. ## Common Misconception Many people use "erosion" to describe both processes—thinking erosion includes the actual breaking down of rock. In reality, **erosion only refers to the movement** of already-weathered material. The breakdown must happen first (weathering), then the movement occurs (erosion). They're related but distinct processes that work in sequence.
