In this world around us, there is little as wondrous as rocks that are Igneous. New crust is being created every day, our earth never seems to stay the same way.  Sometimes the unimaginably hot magma below the surface of the earth pushes its way to the surface, forming new crust. It can be dramatic with enormous volcanic eruptions or it can be unseen, like the new crust forming as tectonic plates diverge at oceanic ridges. Other times, magma gets stuck below the surface, cooling slowly, forming crystals like Granite.  Igneous rock that forms on the surface is called Extrusive Igneous Rocks, while rock that forms beneath the surface is called Intrusive Igneous Rock.

C = (Rhyolite + Obsidian + Scoria) – Granite

D = Sill - Dyke

E = Batholith – Obsidian
