  1. CRCT Question What is the plastic layer that the tectonic plates slide on? • asthenosphere • Lithosphere • Mantle • Crust

  2. Corny Joke of the Day Why didn’t the skeleton go to the party? He had no-body to go with

  3. Heads Up Buttercups QUIZ ON MONDAY

  4. Task #1-Earth’s Structure Tier 1 Great job everyone! • I only wrote down where you missed information • This was a homework grade 

  5. PTTier 2 Options (FORMATIVE) Option 1: Design models to demonstrate the three main tectonic movements. Include a fact card for each movement that describes how to use the model, what causes the movement, and what happens because of that movement. Option 2: Create a script for a play that describes the three major types of boundaries. Be sure to describe the setting and characters. Your play should be typed or written in pen. DUE WEDNESDAY

  6. Rubric COMMUNICATED the following vocabulary (10 pts.): • Lithosphere • Asthenosphere • Convergent-mountain building, volcanoes, Mariana Trench, subduction • Divergent-mid ocean ridge • Transform-San Andres Fault, earthquakes • Convection currents • Plate Tectonics • Mantle 10 pts. Organization 10 pts. presentation

  7. The Theory of Plate Tectonics

  8. Let’s Watch it in Motion http://www.youtube.com/watch?v=Kpoko_l34ZE&feature=related http://www.youtube.com/watch?v=ryrXAGY1dmE&feature=related

  9. Each group will be assigned a hat! • Red Hat-Favorite part • White Hat-Facts • Black Hat-Questions you have about this. Why would this theory not work • Yellow hat-What are some things that you liked • Blue hat- What are some concepts you already knew about?

  10. Plate Tectonics Coffee Talk

  11. The Theory of Plate Motion • The lithosphere is broken into separate sections called plates. They “float” on the asthenosphere • Sea-floor spreading and continental drift into a single theory – The Theory of Plate Tectonics • Plate Tectonics – is the geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion, driven by convection currents in the mantle. • The theory of plate tectonics explains the formation, movement, and subduction of Earth’s plates

  12. 10 Major Plates

  13. Plate Boundaries 1. Transform Boundaries – • Crust is neither created nor destroyed • Place where two plates slip past each other, moving in opposite directions

  14. 2. Divergent Boundaries • Place where two plates move apart • When develops on land, two of Earth’s plates pull apart. A deep valley called a rift valley forms along the divergent boundary • Example: Mid-Atlantic ridge

  15. 3. Convergent Boundaries • Place where two plates come together Three types A. Convergingoceanicplate and oceanic plate collide one plate is subducted through a trench and volcano islands are formed B. Converging oceanic plate and continental plates – when continental plates and oceanic plate collide, the oceanic plate is subducted and volcanoes on land are formed C. Converging continental plates – where two continental plates collide, the crust buckles and mountain ranges form.

  16. The Continents Slow Dance • The plates are moving at a very slow rate of about one to ten centimeters per year. • In areas plates are moving together and others are moving apart.

  17. Worktime • Vocabulary 1-5 (due Nov. 2nd) • Tier 1 Plate tectonics • Choose Tier 2 Plate Tectonics
