Molten material within the Earth is called magma. In simple terms magma can be thought of as molten rock. When magma cools, it solidifies to form rock which is called igneous rock. That is deceptively simple, since the solidification process can be very complex.There is a considerable range of melting temperatures for different compositions of magma.agma. Magma is the term used to describe molten material within the Earth; in simple terms: molten rock. But the molten rock usually contains some suspended crystals or dissolved gases.
Magma, as liquid, preferentially forms in high temperature, low pressure environments within several kilometers of the Earth's surface. Magma compositions may evolve after formation by fractional crystallization, contamination, and magma mixing. By definition rock formed of solidified magma is called igneous rock.agma is a complex high-temperature fluid substance. Temperatures of most magmas are in the range 700 Â°C to 1300 Â°C (or 1300 Â°F to 2400 Â°F), but very rare carbonatite magmas may be as cool as 600 Â°C, and komatiite magmas may have been as hot as 1600 Â°C. Most magmas are silicate mixtures.
