  1. 1. Warm-up, 10.14.2009 Show Mr. Benson what a transverse wave looks like. Next, demonstrate a compressional wave. Montrez M. Benson à ce qu'une onde transversale ressemble. Après, démontrez une vague de compression. Demuestre a Sr. Benson qué una onda transversal parece. Después, demuestre una onda de compresión.
  2. 2. Notes, Chapter 12 <ul><li>The Earth’s crust is composed of a series of plates (tectonic plates) floating on top of the liquid, molten core of the planet. </li></ul><ul><li>Mid-ocean ridge : An underwater mountain created by two tectonic plates moving away from each other. </li></ul><ul><li>Rift Valley: The valley created by two plates moving away from each other. Magma may emerge from these points, cycling crust upwards. </li></ul>
  3. 5. Rift Valley (African Rift Valley, East Africa)
  4. 7. Notes, Chapter 12 <ul><li>Divergent Boundary: Where two plates are moving away from each other. </li></ul><ul><li>Convergent Boundary: Where two plates are moving towards each other. </li></ul><ul><li>Subduction Zone: A kind of convergent zone where two plates come together, one being pushed under the other. </li></ul><ul><li>Transform Boundary: Where two plates are moving along-side each other. Faults form in these areas. </li></ul>
  5. 10. Transform Boundary <ul><li>The Alpine Fault (New Zealand) </li></ul>
  6. 11. <ul><li>Transform Boundary </li></ul>
  7. 12. Plate Tectonics Mini-lab <ul><li>Get with a partner and take out a sheet of paper and a book. </li></ul><ul><li>Fold, cut, and tape your sheet of paper to model each of the different kinds of plate boundaries. </li></ul><ul><li>Color the paper to illustrate different levels of elevation. Red = high elevation. Yellow = medium elevation. Blue = low elevation. </li></ul><ul><li>Look at a map of the world and note the position of mountains. </li></ul>
  8. 13. Midterm Practice: Due Friday <ul><li>P. 13, #4 </li></ul><ul><li>P. 16 #1-2 </li></ul><ul><li>P. 21 #1-5 </li></ul><ul><li>P. 26 #5 </li></ul><ul><li>P. 34, 35 all </li></ul>
  9. 14. Midterm Project (Major Project #3): Science Fair <ul><li>Requirements: </li></ul><ul><ul><li>Must perform an experiment. The experiment can be about anything you choose. Pick something you’re interested in!!! </li></ul></ul><ul><ul><li>A science fair display. Typically a poster board displaying the steps of the scientific method you performed, as well as pictures/photos of the experiment, illustrations/graphs/charts, and various other visual aids. </li></ul></ul><ul><li>Work in pairs. </li></ul>
  10. 17. Wrap-up <ul><li>Who do you think should win a Nobel Prize? Why? </li></ul>
