Weathering and erosion are two processes that work together to break down rocks and minerals into smaller pieces. Weathering is the process of breaking down rocks and minerals into smaller pieces by the action of wind, rain, and ice. Erosion is the process of carrying away those smaller pieces by the action of water, wind, or ice. Together, these two processes can change the surface of the Earth.
Your little learner can identify the difference between weathering and erosion by using pictures.
