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
