Tuesday Warm Up

• Which layer of the Earth do we live on? What is it made out of?

• Which layer of the Earth is the thickest?• What element makes up most of the Inner

Core? (Hint: It’s a metal)

Layers of the Earth:In Depth

Partner Work

List the materials earth was made up of originally (pre-humans, pre-dinosaurs, pre-life)

- Hint: Think of what you learned about earth’s layers yesterday!

Density DemonstrationWhile watching, remember:

- When earth began, it was entirely liquid

So, how do you think earth’s layers are organized and why?

Two types of Crust•Oceanic crust- layer of thin crust, that is underwater (oceans

and seas).•Continental crust-

thick crust that rises above the ocean (mountains and

land).

Crust

• Continental Crust is 30-50 km thick• Oceanic Crust

is 5-10 km thick

Mantle

• It is about 2900 km wide-> thickest layer•500˚C-4000˚C

Outer Core

• It is about 2300 km wide• 4400˚C-

6100˚C

Inner Core

• The reason it is solid is due to the high pressure put on it from the outside layers.

• 7000˚C-8000˚C• Its Diameter (width) is about 2400 km.

Lithosphere and Asthenosphere

Lithosphere: the solid part of the

crust and the very top of the mantle.

Asthenosphere: hotter, softer layer of rock on which the lithosphere

sits

•The Asthenosphere is neither solid or liquid. It is like a hot thick paste: like tar.
