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 ConvectionObjective:
SWBAT identify the characteristics of Earth’s layers
How thick is each Layer??
Inner Core1200 km = 745 miles Miami to Charlotte
Outer Core2250km = 1398 miles Miami to NYC
Mantle2900 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/cm3
OCEANIC = Igneous rock (Basalt), 7 kilometers, *younger than continental crust,
180 billion years old-ish, Density = 3.0g/cm3
Crust31.15 km = 19.36 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
