LAYERS OF
EARTH
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)
Information
(Right side is bigger than the left side)
Crust, Mantle, Core (inner core and
3
Compositional outer core)
Layers of
Earth
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 move
Top-1600 degrees F
Bottom- 4000 degrees F
Key Words
(Left Side is smaller
than the right side)
Outer
Core
Information
(Right side is bigger than the left side)
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.
