Magma is essentially molten rock inside earth, possibly with some trapped gasses. To become rock the magma simply cools and solidifies, essentially freezing.
Magma turns water into steam.
Magma can solidify and cool to form igneous rocks such as granite, basalt, or andesite, depending on the composition and cooling rate of the magma.
