  1. Introduction to Weathering and Erosion

  2. Weathering and Erosion • Weathering = change the appearance of something through long exposure of air/water/nature • Erosion = removing pieces of rocks and transporting them to another by wind and water.

  3. Types of Weathering • Physical • Biological • Chemical

  4. Physical Weathering • The breaking of rocks by: • wind or rain • contraction • water freezing • thermal expansion • This occurs in regions with extreme temperatures

  5. Biological Weathering • Rocks are broken down by living things or decomposed • Broken by: • Lichens • Tree roots

  6. Chemical Weathering • The breaking of rocks when water and rocks interact with each other to create a chemical reaction. • Rocks are broken by: • water • gases

  7. Erosion • Erosion is the process by which the surface of the Earth gets worn down caused by natural elements such as wind and glacial ice. • The key to erosion is something called "fluid flow." Water, air, and even ice are fluids because they to flow from one place to another.

  8. Compare Weathering and Erosion • Similarities • Weathering and erosion are both natural forces that break down rocks and shape Earth’s surface • Both are continuous natural processes that happen over time

  9. Contrast Weathering and Erosion • Differences: • Erosion breaks down rocks but it involves water and wind to move the broken particles to a new location • Weathering breaks the rocks apart with natural forces but the particles stay next to each other
