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?
4.1 Layers of the Earth and Convection Objective: SWBAT identify the characteristics of Earth’s layers
How thick is each Layer??
Inner Core 1200 km = 745 miles Miami to Charlotte
Outer Core 2250km = 1398 miles Miami to NYC
Mantle 2900 km = 1802 miles Miami to the tip of maine Composition: Magma/Rock State of Matter: Semi-Solid
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
Crust km = miles Carowinds to UNCC
LITHOSPHERE – What is it? Combination of BOTH Crust & Upper Mantle 9
ASTHENOSPHERE – What is it? Combination of BOTH MIDDLE & LOWER Mantle 10
