Layers of the Earth

Earth Layers
• The Earth is divided into four main
layers.
*Inner Core
*Outer Core
*Mantle
*Crust
The Crust
* The Earth’s crust is like
the skin of an apple. It
is very thin compared to
the other three layers.
*The crust makes up 1% of
the Earth.
* The crust of the Earth is
broken into many pieces
called plates.
The Mantle
• The mantle is the
layer below the
crust.
• The mantle is the
largest layer of the
Earth.
Outer Core
* The core of the
Earth is like a ball
of very hot metals.
* The outer core is
liquid.
* The outer core is
made up of iron and
is very dense.
Inner Core
* The inner core of
the Earth has
temperatures and
pressures so great
that the metals are
squeezed together
and are not able to
move.
* The inner core is a
solid.
Creating a clay model of the
Earth
The Steps to Making the Layers!
1) First you will need to gather your materials
using the material checklist.

2) Roll the yellow clay in a small ball (represents
inner core).

3) Using the rolling pin, roll out the red clay in a flat
circular shape (represents the outer core)

4) Wrap the red clay around the yellow ball.

5. Using the rolling pin, roll out the orange clay in a
flat circular shape (represents the mantle)

7. Using the rolling pin, roll out the blue clay in a
flat circular shape.

8. Now take the green clay and separate the clay
into 5 small pieces.

10. Press the green pieces of clay in different
locations into the flattened blue clay.

11. Using the rolling pin, roll the green clay into the
blue clay until it is smooth.

12. Wrap the green and blue clay around the
orange ball (this represents the Earth’s crust).

13. Take the knife and cut the clay model of the
Earth in half so as to see all the layers of the
Earth.
