Magma can be found in the mantle or molten crust. Magma (from Ancient Greek μάγμα (mágma) ''thick unguent'') is the molten or semi-molten natural material from which all igneous rocks are formed. Magma (sometimes colloquially but incorrectly referred to as lava by laypeople) is found beneath the surface of the Earth, and evidence of magmatism has …
