Transcript of "2 Intro To Landforms And Landscapes"

  1. 1. Geomorphological Landforms
  2. 2. Geography = People + Environment
  3. 3. "Geography is the study of The Earth as the home of people" Yi-Fu Tuan 1991 Human behaviour Human impact on the environment Sustainable development and use of resources Interdependence Scale
  4. 4. BUT………….. <ul><li>We must not forget the Earth is 4,600,000,000 years old!!!!!!! </li></ul><ul><li>Humans (homo sapiens) have only been on the Earth for 100,000 years. </li></ul><ul><li>We only have 10,000 years of recorded history </li></ul><ul><li>It is 2007 </li></ul>
  5. 5. For the last 3.7 billion years since the Earth’s crust formed Geomorphological processes have been shaping the Earth.
  6. 6. The Rock Cycle
  7. 7. http://www.open2.net/geologytoolkit/geologyhome.html
  8. 8. Geomorphological Processes Tectonic movement – Tectonic plates moving Weathering – Breaking down, decomposition of rocks from contact with atmosphere Erosion – Rocks and soils being broken down, disintegrated and removed Transportation – Rocks and soils being moved Deposition – Rocks and soils being dropped down
  9. 9. Geomorphological processes need agents to actually do the work…
  10. 10. Gravity
  11. 11. Water - Rivers
  12. 12. Water - Sea
  13. 13. Wind
  14. 14. Ice - Glaciers
  15. 15. Now its your turn…. <ul><li>Explain how your landform was formed. </li></ul><ul><li>Which geomorphological processes? </li></ul><ul><li>Which agent? </li></ul>
  16. 16. Rock Pedestal
  17. 17. Erratic
  18. 18. Spit
  19. 19. Oxbow lake
  20. 20. Stack
  21. 21. Fold - Unconformity
  22. 22. Transportation Process <ul><li>The debris produced by weathering and the sediment removed by EROSION is transported by these agents. </li></ul><ul><li>Gravity – Avalanche, landslide, soil creep </li></ul><ul><li>Wind – Sandstorm, suspension, saltation </li></ul><ul><li>Rivers – Traction, saltation, suspension, solution </li></ul><ul><li>Sea – Longshore Drift </li></ul><ul><li>Glacier – Moraine, ice flow, rotational flow </li></ul>
