*[[Outer Core]]: The [[Outer Core]] is a [[liquid]] layer below the [[Mantle]].
*[[Inner Core]]: Underneath the [[Outer Core]] is the [[Inner Core]] at the very centre of [[Earth]]. It is a [[solid]] [[sphere]].
====Crust====
The [[Crust]] is split into several lumps that float on the [[Mantle]]. They are called [[Tectonic Plate]]s. They move around separately and and when the rub against each other this causes [[Earthquake]]s. If one [[Tectonic Plate]] moves on top of another the [[Tectonic Plate]] underneath starts to [[melt]] and [[magma]] rises up to make [[Volcano]]es.
