What is Magma Magma is a mixture of molten rock, dissolved gases, and solid mineral crystals. It originates deep within the Earth’s mantle or rust and can rise to the surface, where it erupts as lava or solidifies underground to form igneous rocks. The composition and behavior of magma depend on its source, formation conditions, and the geological environment. How Does Magma Form Magma forms through the partial melting of rocks in the Earth’s mantle or crust. This melting occurs under ... Magma can be found in the mantle or the crust. Magma (from Ancient Greek μάγμα (mágma) 'thick unguent ') [1] is the molten or semi-molten natural material from which all igneous rocks are formed. [2] . Magma, the molten rock beneath Earth's surface, holds many fascinating secrets. From its role in forming new land to its impact on volcanic eruptions, magma shapes our planet in ways we often overlook. Magma is naturally occurring molten or semi-molten rock material, generated within the Earth from which igneous rocks are derived through solidification and related processes. Magma is found beneath the surface of the Earth.
