    *Mantle

    *Crust (Lithosphere)


The crust lithosphere

The Crust (Lithosphere)

* 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.

*It is composed mainly of granite and basalt.


The mantle

The Mantle

* The mantle is the layer below the crust.

* The mantle is the largest layer of the Earth.

* This layer is made of heavy dense rock.


Outer core

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

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.
