Weathering & Erosion ⛰️

What are Weathering and Erosion? 🤔

**Weathering** and **erosion** are two important ways that our Earth's surface changes. They both break down and move rocks and dirt, but they do it in different ways.

**Weathering** is when rocks and soil are broken into smaller pieces. This can be caused by wind, rain, ice, or even living things like plants. The tiny rock pieces don't go anywhere, they just break apart in place.

**Erosion** is when those broken pieces of rock and soil are moved away from their spot. This is also caused by wind, water, and ice. Think of a river carrying tiny pebbles downstream. That's erosion!
