  • Using the hot plates and glass plate from earlier, have sponge cut outs of the continents -can compare to a beaker with cold water with a sponge in it not moving
  • Day 3 Earth Layers

    1. 1. 9/15/11 LEQ: HOW does continental drift happen? (reminder: complete sentences!)1. What is Pangaea?2. What is the theory of continental drift?3. What different types of evidence do wehave to support this theory?4. Is it possible to find ice evidence inJamaica? Explain.
    2. 2. AGENDA:• WORK TIME• ACTIVATING STRATEGY• NEW LEQ NOTES/MATERIAL• DEMOS• PRACTICE
    3. 3. Today’s LEQ: How does continental drift happen?By the end of today, you should be able to…1. Explain the geologic conditions that allow continents to move2. Describe convection currents that cause the continents to move

    10. 10. Making Inferences:• What do all of these things have in common? HEAT!
    11. 11. Key Point• The movement of the food coloring represents the movement of magma in the Earth’s mantle• This movement is what causes Earth’s continents to move away from each other
    12. 12. DEFINITION: DIAGRAM:The cycle of magma under the crust as it heats, rises, cools, and sinks CONVECTIOCAUSES: EFFECTS: N CURRENTS
    13. 13. DIAGRAM:Plates move! Mantle OUTER CORE INNER CORE
    14. 14. HOT Q: • How would the position of the continents have been different if the inner core was made of a solid block of ice and not hot iron? a. The continents would still be one mega continent, Pangaea b. The continents would be the same position as they are today
    15. 15. (THIS GOES UNDERNEATH YOUR FRAYER DIAGRAM)LITHOSPHERE:ASTHENOSPHERE:TECTONIC PLATES:
    16. 16. CONTINENTS ADRIFT• What form of matter (solid, liquid, or gas) do you think the crust is made of?
    17. 17. What about the oceanic crust?!

    19. 19. DEMO: CONTINENTS ADRIFT• What form of matter do you think lies underneath the lithosphere?

    24. 24. Steps of Convection Comics!!1. Use the list at your desk to put the steps of convection in order (the first one is done for you)2. Draw a comic strip for the four steps of convection currents!3. Your comic strip should include: A) 4 boxes (1 for each step in the cycle) B) 4 illustrations EXAMPLE: C) the four steps of convection (you may copyLiquid magma in the mantle isheated by the earth’s core the 4 steps exactly if you like, but you are encouraged to be creative!) (add illustration here)
    25. 25. SUMMARIZER• Watch the video again• This preview is for a movie called “Ice Age: Continental Drift”• In 3 sentences or more, explain why the continents ACTAULLY move—(hint—it is not because of a squirrel running around…)• YOU MUST USE EACH OF THE FOLLOWING VOCABULARY FOCUS WORDS in your answer!!! -Lithosphere -Asthenosphere -Convection Current(s) -Tectonic plates
    26. 26. Let’s REVIEW: Earn your seat• What is the name of the mega continent?• Who proposed the theory of continental drift?• What is the theory of continental drift?• What are the 3 types of evidence that support this theory?• Why do the continents move apart?• How do convection currents cause the plates to move?• Why is it possible we could find fossils of tropical plants in Alaska?• How is it possible that similar animal fossils are found on two separate continents?
