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 Demonstration
While 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 crustthick 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˚C6100˚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.
