As you watch the video, write down 5 things that you learned. Also write down any
vocabulary words that are important

The Four Layers
• List the four layers of the Earth. Write how thick
each layer is beside its name
Name of the Layer
Thickness
Crust
5-25 miles
Mantle
1800 miles
Outer Core
1400 miles
Inner Core
800 miles
The 3 Compositional Layers
(What they are made of)
1. Crust (Continental and Oceanic)-the
thin and solid outermost layer of the
Earth-mostly rock
2. Mantle-the layer of rock between
the Earth’s crust and core (iron and
magnesium)
3. Core-the central part of the Earth
below the mantle (iron and nickel)
The 5 Physical Layers
(solid vs liquid, rigid vs soft)
1. Lithosphere-the crust and upper mantle
(rigid/stiff)
2. Asthenosphere- soft layer of the mantle
(plastic)
3. Mesosphere- solid layer of the mantle
4. Outer Core- liquid, outer layer of the
core. Produces the Earth’s magnetic
field
5. Inner Core- solid, inner layer of the
core
The Crust
5. The crust is like the skin of an
apple.
6. At 1600 degrees Fahrenheit, rocks
begin to melt.
7. The crust of the Earth is broken into
many pieces called plates.
8. The plates “float” on the soft,
plastic mantle which is located below
the crust.
The Lithosphere
9. The crust is composed of two basic rock
types granite and basalt.
10.The crust and the upper layer of the mantle
together make up a zone of rigid rock called
the lithosphere.
11. The layer below the rigid lithosphere is a
zone of asphalt-like consistency called the
asthenosphere. It is the part of the mantle
that flows and moves the plates of the
Earth.

Asthenosphere
The Mantle
12. The mantle is the layer located under the
sima. It is the largest layer of the Earth,
1800 miles thick.
13. The movement of the mantle is the reason
that the plates of the Earth move!
14. The temperature at the top of the mantle
is about 1600 degrees Fahrenheit.
15. The temperature at the bottom of the
mantle is about 4000 degrees Fahrenheit.
Convection Currents
16.Convection Currents are caused by
the very hot material at the deepest
part of the mantle rising, then cooling,
sinking again and then heating, rising
and repeating the cycle over and over.

The Outer Core
17.The outer core is so hot that the metals in
it are all in the liquid state.
18.The outer core is composed of the melted
metals nickel and iron.
The Inner Core
19. 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.
20. The temperatures may reach 9000
degrees Fahrenheit.
