Melting is the process by which a substance changes from the solid phase to the liquid phase. Melting is also known as fusion, although this term has several meanings. Melting occurs when the internal energy of a solid increases, usually through the application of heat or pressure, such that the molecules become less ordered.

It is so hot deep within the earth that some rocks slowly melt and turn into a thick flowing matter known as magma. Since it is lighter than the solid rock around it, the magma rises and gets collected in magma chambers. Eventually, some of the magma pushes through fissures and vents in the earth’s surface. Hence a volcanic eruption occurs and the erupted magma is known as lava.
