2. Weathering  the breaking down of rocks into smaller pieces, mechanically or chemically

3. Erosion  the movement of sediments to a new location because of weathering  ????????  (How is this concept supported by the law of conservation of mass?)

4. Factors of Weathering And Erosion

5. Water Runoff is water flowing on Earth’s surface that causes erosion.

6. Ice In some parts of the world, ice is an agent of erosion. Ice forms continental and valley glaciers.

7. Air Wind, which is moving air, blows small particles from Earth’s surface, which is called deflation. Pits in rocks or polishes surfaces smooth as sediments are blown by strong winds, which is abrasion.
