===About Igneous Rocks===
: When [[magma]] or [[lava]] [[freezing|freezes]] it is called an '''igneous''' rock.
: When the [[magma]] is trapped underground it [[freezing|freezes]] slowly and this makes very large [[cyrstalcrystal]]s in the rock. This is called [[intrustive]] rock.
: When the [[lava]] comes out of the [[volcano]] it cools down and [[freezing|freezes]] quickly making small [[crystal]]s. This is called [[extrusive]] rock.
: [[Igneous]] rocks have sharp interlocking [[Grain (Rock)|grains]].
