Transcript

  • 1. Weathering and Erosion
  • 2. Weathering
    • The breakdown do the materials of Earth’s crust into smaller pieces.
  • 3. Physical Weathering
    • Process by which rocks are broken down into smaller pieces by external conditions.
    • Types of Physical weathering
      • Frost heaving and Frost wedging
      • Plant roots
      • Friction and impact
      • Burrowing of animals
      • Temperature changes
  • 4. Frost Wedging
  • 5. Frost Heaving
  • 6. Plant Roots
  • 7. Friction and Repeated Impact
  • 8. Burrowing of Animals
  • 9. Temperature Changes
  • 10. Chemical Weathering
    • The process that breaks down rock through chemical changes.
    • The agents of chemical weathering
      • Water
      • Oxygen
      • Carbon dioxide
      • Living organisms
      • Acid rain
  • 11. Water
    • Water weathers rock by dissolving it
  • 12. Oxygen
    • Iron combines with oxygen in the presence of water in a processes called oxidation
    • The product of oxidation is rust
  • 13. Carbon Dioxide
    • CO 2 dissolves in rain water and creates carbonic acid
    • Carbonic acid easily weathers limestone and marble
  • 14. Living Organisms
    • Lichens that grow on rocks produce weak acids that chemically weather rock
  • 15. Acid Rain
    • Compounds from burning coal, oil and gas react chemically with water forming acids.
    • Acid rain causes very rapid chemical weathering
  • 16. Karst Topography
    • A type of landscape in rainy regions where there is limestone near the surface, characterized by caves, sinkholes, and disappearing streams.
    • Created by chemical weathering of limestone
  • 17. Features of Karst: Sinkholes
  • 18. Features of Karst: Caves
  • 19. Features of Karst: Disappearing Streams
  • 20. Erosion
    • The process by which water, ice, wind or gravity moves fragments of rock and soil.
  • 21. Water Erosion
    • Rivers, streams, and runoff
  • 22. Ice Erosion
    • Glaciers
  • 23. Wind Erosion
  • 24. Mass Movements
    • Landslides, mudslides, slump and creep
