  1. Layers of the Earth Open books to page 326.

  2. How are the earth’s layers similar to an egg? Shell= crust Layers Limitations? Earth’s Layers

  3. Make a model of Earth Using paper, make a pie-shaped piece to resemble the Earth. On the front, label the following: Inner core Outer core Mantle Lithosphere (includes Crust)

  4. Open up your segment of the Earth and… • Label the state of matter of each layer. • What elements make each layer? • Inside the foldable, show where the asthenosphere is. • Others on board. Page 326 -329.

  5. Lithosphere (crust) Asthenosphere (part of mantle) Mantle Outer core Inner core

  6. What is the center layer called?What state of matter is it?What is it made of? INNER CORE SOLID IRON AND NICKEL

  7. Inner core Solid Nickel and iron Deepest layer, so…. Greatest pressure Also the Hottest! (8,0000F)

  8. The next layer of the Earth after theinner core would be the……What state of matter is the outer core?What elements are in the outer core? OUTER CORE LIQUID Iron and Nickel

  9. Outer core Liquid Nickel and iron Due to flow of liquid metal, gives us our magnetic field.

  10. Where is there liquid nickel and iron? As the liquid iron and nickel in the outer core circulate, it creates a magnetic field.

  11. Why do you think the inner core is solid and the outer core is liquid? The core of our Earth is tremendously hot. It is believed to have a temperature of 7,000 degrees Celsius. Pressure keeps the inner core a solid, but allows the outer core to be a melted, liquid state.

  12. So what 2 things increase as you travel toward the Earth’s center? • Heat and Pressure!

  13. Mantle solid and plastic Semi-solid, semi-liquid Magnesium, Iron Silicon, Oxygen

  14. The mantle is a layer that is kind of like tar on a hot day. It flows, but very, very slowly. .

  15. Asthenosphere (upper layer of the mantle) Plastic (flows, like Peanut butter) Magma Convection currents here!

  16. The asthenosphere is just below the lithosphere. It is part of the mantle. The asthenosphere is rock that flows slowly, like hot asphalt or peanut butter.

  17. The lithosphere includes the crust of the Earth and the upper mantle. . It is solid. Crust: Oxygen and Silicon

  18. The outermost layer of our Earth is called the crust. Lava Mountains Water Least pressure Coolest

  19. Lithosphere, which includes the crust solid

  20. Oceanic and Continental Crust 3 miles thick 65 miles thick Deepest drilling about 7 miles

  21. What is this layer? State of matter? Inner core Solid

  22. What is this layer? State of matter? Lithosphere Solid

  23. What is this layer? State of matter? Mantle Plastic

  24. What is this layer? State of matter? Outer core Liquid

  25. Relative Masses - Earth http://www.uwgb.edu/dutchs/202ovhds/quakes.htm

  26. Name the 5 basic layers of the Earth (mentioned in your book) in order of their temperatures, from highest to lowest.

  27. Name the layer associated with this clip… CRUST

  28. Name the layer associated with this clip… OUTER CORE

  29. Name the layer associated with this clip… OCEANIC CRUST

  30. Name the layer associated with these graphics… CORE

  31. Name the layer associated with this clip… OUTER CORE

  32. Name the layer associated with this clip… Wrapper Lithosphere Hot, Melted Fudge mantle

  33. Convection – What is it? Why do we care? Convection Source: http://www.uwgb.edu/dutchs/EnvSC102Notes/102HowEarthWorks.HTM

  34. 5-40 km 2900 km 2200 km 1200 km Our scale is: 60 km = 1 mm Label the layers and state of matter. Show convection currents in mantle.
