Presentation Transcript

  1. WEATHERING The process of rock breaking down into smaller pieces

  2. AGENTS OF WEATHERING • PHYSICAL AGENTS • (Physical Changes) • Glaciers • Animals • Ice • Ocean Waves • Plant Roots

  3. Animal Actions

  4. Ice Wedging

  5. CHEMICAL AGENTS OF WEATHERING • Plant Acids • Acid Rain • Oxidation • (CHEMICAL CHANGES)

  6. Acid Rain

  7. EROSION Process of weathered rocks being carried away

  8. AGENTS OF EROSION • Main force: gravity • Sediments removed & carried by glaciers, wind, water, and gravity (agents) • Moving glaciers smooth and polish rock below • Wind moves loose sand, silt & clay • Moving sand sandblasts a surface • Most important agent of erosion is running water • Particles carried by stream called the load

  9. LANDSLIDE (due to gravity)

  10. DEPOSITION Process of sediments settling in a new location

  11. Colorado River Alluvial Fan

  12. JOURNAL ENTRY 1/28/2013 • What would be the result to a topographical map after a forest fire? • What would be the result to a topographical map after a landslide? • Is all erosion bad for the earth?
