Magma is a molten and semi-molten rock mixture found under the surface of the Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases.
There are many types of magma. One is called felsic magma. Felsic magma is thick (high viscosity) and has much of a mineral called silica. It mostly makes light-coloured rocks. Another type is called mafic magma, which is runny and has less silica. It usually makes dark-coloured rocks. A third type is intermediate magma. It is like both the other types.
