Metamorphic rock becomes magma, erupts and cools Into Igneous rock. Igneous Rock Igneous rocks is a rock that has formed from cooling and solidification of magma and lava.  once it errupts onto the surface we call it lava when it's deep inside the earth, under the surface we called it magma TYPES OF IGNEOUS ROCK INTRUSIVE EXTRUSIVE solidify within Earth.

Felsic rocks tend to be light-colored and have a low density. The terms derives from felspar and silica ULTRAMAFIC: INTERMEDIATE: These are low in silica and consist These are moderate in silica and consist over 90 percent made up of mafic of feldspar. Intermediate rocks tend to minerals. be dark-colored and have a high density.
