3. The Theory of Plate Tectonics
Earth’s crust is broken into about 19 pieces that are in constant motion

4. Warm up!
How are the earth’s layers similar to an egg?

5. Earth’s Layers How are the earth’s layers similar to an egg?
Shell = crust
Egg white = mantle
Yolk = core

7. The 3 Main Parts
1. Crust
2. Mantle
3. Core

8. The Crust Outer layer (shell) Thinnest layer Solid 2 types of crust
Oceanic Crust (very dense)
Continental Crust (less dense)

9. The Crust Outer layer (shell) Thinnest layer 2 types of crust
Oceanic Crust (very dense)
Continental Crust (less dense)

10. Less Dense >
More Dense >

12. The Mantle Middle layer (egg white) Thickest Layer
Solid, but able to flow slowly

13. The Core Center (like the yolk) Hottest part, mostly made of iron
Has 2 parts
Liquid outer core
Solid Inner core

14. The Core Center (Like the yolk) Hottest part, made of mostly iron
Has 2 parts
Liquid outer core
Solid Inner core

15. Layers of the Earth Crust Mantle Core Directions:
Put your name at the top
Label the parts of the Earth
(Crust, Mantle, or Core)
3. Use the Color Code to color
each part of the Earth
