Weathering and erosion

  1. 1. Weathering and Erosion<br />Landforms<br />Palmer – 5th Grade<br />
  2. 2. Lesson Goal<br />I understand, recognize, and explain how weathering and erosion create and change landforms on earth<br />
  3. 3. Review<br />Last lesson, we learned how the earth’s tectonic plates move and create mountains, volcanoes, and earthquakes.<br />
  4. 4. Review<br />
  5. 5. Introduction<br />In this lesson, we will learn how land changes and moves and learn some new landforms.<br />
  6. 6. Introduction<br />
  7. 7. Introduction<br />
  8. 8. Vocabulary<br />For this lesson, we will need some vocabulary and notes in our notebooks.<br />
  9. 9. Physical Weathering<br />The breaking down of land by wind, water, or ice.<br />
  10. 10. Weathering<br />
  11. 11. Physical Weathering<br />1. Give an example of physical weathering.<br />
  12. 12. Chemical Weathering<br />The breaking down of land by acids and gases<br />
  13. 13. Weathering<br />
  14. 14. Chemical Weathering<br />2. Give an example of chemical weathering.<br />
  15. 15. Weathering<br />
  16. 16. Weathering<br />
  17. 17. Weathering<br />3. Does weathering change the earth’s surface quickly or slowly?<br />
  18. 18. Erosion<br />When land is moved from one place to another by wind, water, ice, or gravity<br />
  19. 19. Erosion<br />
  20. 20. Erosion<br />
  21. 21. Erosion<br />4. What is it called when land is moved to a different place?<br />
  22. 22. Sediment<br />Dirt, rocks, and sand that is moved by erosion<br />
  23. 23. Deposition<br />When sediment is deposited, or left after being <br />moved by <br />erosion<br />
  24. 24. Dune<br />Sediment deposited by wind and piled<br />into hills<br />
  25. 25. Delta<br />Sediment deposited at the end of a <br />river<br />or stream<br />
  26. 26. Deposition<br />
  27. 27. Deposition<br />
  28. 28. Deposition<br />6. Where do we normally find deltas?<br />
  29. 29. Deposition<br />7. Where do we normally find sand dunes?<br />
  30. 30. Mass Wasting<br />When a large amount of land moves <br />downhill<br />
  31. 31. Landslide<br />When land moves <br />downhill from gravity<br />
  32. 32. Avalanche<br />When a landslide is caused by a <br />large amount <br />of snow sliding downhill<br />
  33. 33. Mass Wasting<br />
  34. 34. Deposition<br />8. What force mainly causes mass wasting?<br />
  35. 35. Human effect<br />The way humans change the land<br />
  36. 36. Human Effect<br />
  37. 37. Human effect<br />9. What is a way humans can effect the land?<br />
  38. 38. Conclusion<br />
  39. 39. Conclusion<br />
  40. 40. Human effect<br />10. Name three ways land can change over time.<br />
  41. 41. Magic School Bus<br />
  42. 42. Lesson Goal<br />I understand, recognize, and explain how weathering and erosion create and change landforms on earth<br />
