1. Earth’s Layers Aim= Which layer of Earth is the thinnest?

3. Earth’s Layers Crust – Thin outer layer Mantle – Hot / viscous rock
Liquid outer core – Metallic
Solid inner core – Iron and Nickel

4. Layers of the Earth Skin of the peach is the crust
Meat of the peach is the mantle
Pit of the peach is the core

5. 1) Crust The lithosphere 2 types
Continental: Thicker, less dense, felsic (granite)
Oceanic: Thinner, more dense, Mafic, (Basaltic)
Beneath the crust is the MOHO (boundary between crust and mantle)

6. 2) Mantle Asthenosphere: Stiffer Mantle
Upper Mantle, Plastic, soft malleable
Stiffer Mantle
Solid, thick

7. 3) Outer Core
Liquid
Iron and Nickel Composition

8. 4) Inner Core
Solid
Iron and Nickel Composition

9. 5) Relationships AS Depth Increases, Pressure Increases
As Depth Increases, Temperature Increases

10. What is the pressure at 5000km?
At what depth is the temperature 3000 C?
