5th Grade-Ch. 9 Lesson 1 What is the Structure of Earth

  1. 1. Ch. 9 Lesson 1 What is the structure of Earth?
  2. 2. 4 layers of Earth
  3. 3. The Structure of Earth's Interior [01:32]
  4. 4. Another Structure of the earth animation
  5. 5. crust outermost, thinnest layer continental crust oceanic crust made of granite- incl. continents made of basalt- incl. ocean floor- 6-11 km thick
  6. 7. continental rise = beginning of oceanic crust
  7. 8. Structure of the Earth animation - Shows currents in mantle mantle solid hot rock- can flow like liquid top part + crust lithosphere
  8. 10. core- center made mostly of iron 2 parts: magnetic field outer core- liquid (flows in currents) inner core- solid
  9. 12. The Four Layers of the Earth's Interior: Inner Core, Outer Core, Mantle, and Crust [01:16]
  10. 14. 3. test materials to see how respond to heat & pressure 2. measure earthquake vibrations- seismograph 1. study mantle material from cracks Ways scientists study Earth’s interior
  11. 15. The Mantle: The Asthenosphere, Upper Mantle, and Lower Mantle [02:29]
  12. 17. Name that layer Online Quiz
  13. 18. core <ul><li>Earth’s center </li></ul>
  14. 19. crust <ul><li>made of granite or basalt </li></ul>
  15. 20. core <ul><li>made mostly of iron </li></ul>
  16. 21. crust <ul><li>outermost, thinnest </li></ul><ul><li>layer </li></ul>
  17. 22. mantle <ul><li>solid hot rock that can flow like liquid </li></ul>
  18. 23. core <ul><li>creates Earth’s magnetic field </li></ul>
  19. 24. mantle <ul><li>biggest layer of Earth </li></ul>
  20. 25. mantle + crust <ul><li>together form lithosphere </li></ul>
  21. 26. core <ul><li>inner part is solid </li></ul>
  22. 27. continental crust <ul><li>includes North America, South America and Asia </li></ul>
  23. 29. The Earth Bowl <ul><li>The homework monitor will need to get a tray which contains the following: </li></ul><ul><li>A plastic baggie, with graham cracker. </li></ul><ul><li>Nilla wafer cookies A container of black cherry Jell-O </li></ul><ul><li>A container of lemon Jell-O </li></ul><ul><li>A spoon </li></ul><ul><li>A bowl </li></ul><ul><li>DO NOT TOUCH ANY OF THE MATERIALS AFTER YOU HAVE RECEIVED THEM. WAIT UNTIL I EXPLAIN WHAT TO DO. </li></ul>
  24. 30. Steps to Making the Layers of the Earth! <ul><li>Put marshmallow in the bottom of the cup. </li></ul><ul><li>Next, lemon Jell-O and put it in the bowl. </li></ul><ul><li>Then, put black cherry Jell-O on top of the lemon Jell-O. </li></ul><ul><li>Last, you will need the plastic baggie containing graham crackers. Break the graham crackers up in the bag. DO NOT POUND TOO HARD! YOU DON’T WANT THE BAG TO BREAK! Sprinkle the crumbs on top of the black cherry Jell-O. </li></ul>
  25. 31. You have now made the Layers of the Earth. *The Crust (graham crackers) *The Mantle (black cherry) * The Outer Core (orange) * The Inner Core (marshmallow) Draw a picture of it in your notebook, labeling it with the name of the layer and the ingredient.
