The Earth is divided into four main layers from outermost to innermost: the crust, mantle, outer core, and inner core. The crust makes up only 1% of the Earth's volume and is broken into tectonic plates, while the mantle is the largest layer and divided into upper and lower sections. Below the mantle lies the outer core, which is liquid and composed of iron, and the inner core, where extreme heat and pressure cause metals to be squeezed into a solid state.

• The Earth is divided into four main
layers.
*Inner Core
*Outer Core
*Mantle
*Crust

3. The CrustThe 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.

4. The MantleThe Mantle
• The mantle is the
layer below the
crust.
• The mantle is the
largest layer of the
Earth.
• The mantle is
divided into two
regions: the upper
and lower sections.

5. Outer CoreOuter 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.

6. Inner CoreInner 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.
