6th grade Ch. 1 Sec. 1 Earth's Interior

  1. 1. Ch. 1 Sec. 1 Earth’s Interior
  2. 2. Activity pg. 6 - How do Scientists Find Out What’s Inside Earth? <ul><li>Without opening the canisters, what differences do you notice between them? </li></ul><ul><li>Apart from their appearance on the outside, are the canisters similar in any way? </li></ul><ul><li>How did you obtain this evidence? </li></ul>Canister Observations 1 2 3
  3. 3. <ul><li>direct evidence from rock samples </li></ul><ul><li>indirect evidence from seismic waves- earthquakes </li></ul>geologists use 2 types of evidence to learn about Earth’s interior
  4. 4. Layers of Earth 3 main layers of Earth’s interior crust mantle <ul><li>core - </li></ul><ul><li>inner core </li></ul><ul><li>outer core </li></ul>
  5. 5. <ul><li>The crust is a layer of solid rock that includes both dry land and the ocean floor. </li></ul>The Crust
  6. 6. crust <ul><ul><li>layer of rock </li></ul></ul><ul><ul><li>forms Earth’s outer skin </li></ul></ul><ul><ul><li>  </li></ul></ul>
  7. 7. crust <ul><ul><li>2 types of crust : </li></ul></ul><ul><ul><li>oceanic crust </li></ul></ul><ul><ul><ul><li>made of basalt- dark rock w/ fine texture </li></ul></ul></ul><ul><ul><li>continental crust </li></ul></ul><ul><ul><ul><li>made of granite - rock w/ light color & coarse texture  </li></ul></ul></ul>
  8. 9. <ul><li>Earth’s mantle is made up of rock that is very hot, but solid. Scientists divide the mantle into layers based on the physical characteristics of those layers. </li></ul>The Mantle
  9. 10. mantle <ul><ul><li>layer of hot solid rock </li></ul></ul><ul><ul><li>from base of crust  3,000 km deep </li></ul></ul>
  10. 11. 2 parts of mantle: <ul><ul><li>lithosphere = </li></ul></ul><ul><ul><li>rigid layer of uppermost part of mantle & crust </li></ul></ul><ul><ul><li>floats on top of 2. asthenosphere </li></ul></ul><ul><ul><li>soft layer that flows </li></ul></ul>
  11. 12. core <ul><ul><li>2 parts : </li></ul></ul><ul><ul><li>inner core- solid </li></ul></ul><ul><ul><li>outer core- liquid </li></ul></ul><ul><ul><li>currents in liquid outer core force solid inner core to spin  produces Earth’s magnetic field </li></ul></ul>
  12. 13. <ul><ul><li>made of iron & nickel </li></ul></ul>core
  13. 18. Creating Data Tables pg. 11 Depth Name of Layer What Layer Is Made Of 20 km 150 km 2,000 km 4,000 km 6,000 km
  14. 19. How to make a model of the <ul><li>In a Ziploc bag, combine 1/2 cup (1 bottle) of glue and 1/2 cup of warm water. </li></ul><ul><li>Add a few drops of food coloring to tint the mixture to the desired shade. </li></ul><ul><li>In a second Ziploc bag, combine 1 teaspoon of Borax and 1/2 cup of water. Mix thoroughly. </li></ul><ul><li>Pour the Borax mixture into the glue mixture. It will be very thick. </li></ul><ul><li>Knead slightly as the mixture starts to come together. </li></ul>ASTHENOSPHERE -SOFT LAYER OF THE MANTLE ON WHICH THE LITHOSPHERE FLOATS
  15. 20. Edible Earth <ul><li>Write a description of each layer of Earth. </li></ul>Crust= graham crackers Mantle= black cherry Jello Outer core= peach Jello Inner core= raspberry Jello
  16. 21. Write a story about a journey to the center of Earth. Directions are on pg. 13 in your textbook. <ul><li>1-2 written pages + 1 page with a picture </li></ul><ul><li>Have a beginning, middle and end to your story </li></ul><ul><li>You must include at least 3 facts for each main layer (composition, depth, thickness, how the layers are separated into different layers,etc.) </li></ul>
  17. 22. Activity: Core of the Matter <ul><li>Build a 3-D model of the planets to depict the interiors of each. Punch a hole in a paper plate and spin it on a phonographic record player at 77 rpm. With different colored markers, draw the layers of the planet to correspond in scale to the planet’s interior. For example, for a simplified earth draw to scale a core, a mantle, and a crust. Repeat this on both sides of three plates. (On some turntables, an upside down plate will override the rotating section. To get a plate to spin upside down, first place a spare plate right-side-up on the player, then place the upside down plate on that.) </li></ul><ul><li>Cut and combine the plates so the three of them intersect perpendicular to each other on an X-, a Y-, and a Z-axis. To do this, cut a slit halfway across two plates and intertwine them. Cut a third plate in half. On each half cut a slit from the cut edge (what was formerly the center of the plate) halfway outward. Cut partial slits on the combined plates to accommodate the two halves. Hang and shabang. </li></ul>
