1. Warm Up 1)What are the layers of the Earth? 2)What is the core of the Earth made of? 3) What do earthquakes & volcanoes have in common?

2. 4.1 Layers of the Earth and Convection Objective: SWBAT identify the characteristics of Earth’s layers

3. How thick is each Layer??

4. Inner Core 1200 km = 745 miles  Miami to Charlotte

5. Outer Core 2250km = 1398 miles  Miami to NYC

6. Mantle 2900 km = 1802 miles  Miami to the tip of maine Composition: Magma/Rock State of Matter: Semi-Solid

7. Crust 7 CONTINENTAL = Granodiorite Rock, 40 kilometers, solid, *over 4 billions years old, Density = 2.7g/cm 3 OCEANIC = Igneous rock (Basalt), 7 kilometers, *younger than continental crust, 180 billion years old-ish, Density = 3.0g/cm 3

8. Crust 31.15 km = 19.36 miles Carowinds to UNCC

9. LITHOSPHERE – What is it? Combination of BOTH Crust & Upper Mantle 9

10. ASTHENOSPHERE – What is it? Combination of BOTH MIDDLE & LOWER Mantle 10
