Criteria for Success
I will label the layers of the earth
on a diagram.
CORNELL NOTES
Key Words(Left Side is smaller than the right side)

3 Compositional Layers of Earth
Crust, Mantle, Core (inner core and outer core)
Key Words(Left Side is smaller than the right side)
Information(Right side is bigger than the left side)
Crust
5-25 miles
Continental Crust (makes up continents)Oceanic Crust (makes up ocean floor)
The thin and solid outermost layer of the Earth-mostly rock
Like the skin of an apple
At 1600 degrees Fahrenheit, rocks begin to melt
Broken into many pieces called plates
The plates “float” on the soft plastic mantle which is located below the crust
Key Words(Left Side is smaller than the right side)
Information(Right side is bigger than the left side)
Mantle 1800 miles
the layer of rock between the Earth’s crust and core (iron and magnesium)Largest layer of the earth
The movement of the mantle is the reason that plates of the Earth moveTop-1600 degrees FBottom- 4000 degrees F
Key Words(Left Side is smaller than the right side)
Information(Right side is bigger than the left side)
Outer Core
1400 miles
Liquid state
Composed of the melted metals nickel and iron
Key Words(Left Side is smaller than the right side)
Information(Right side is bigger than the left side)
Inner Core
800 miles
Solid, inner layer of the core
The inner core has temperatures and pressure so great that the metals are squeezed together and are forced to vibrate in place as a solid.The temperatures may reach 9000 degrees Fahrenheit.
