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.
1 Subduction is the process by which continental crust slides beneath another portion of crust. 2  The subducting crust melts and becomes magma, the material that fuels volcanic eruption. 3  The melted crust contains carbon in the sediments and soils, thus recycling it through the mantle of the earth. The melted crust convecting through the mantle will eventually resurface in the form of lava during eruptions from volcanoes. 2  These volcanoes were originally formed by tectonic forces--where there is an excess of magma below the crust due to subduction, it is forced to erupt. 3  The process of eruption includes degassing.
