What must happen first before magma rise to the surface?

Before magma can rise to the surface, it must first be generated through melting of the Earth's mantle or crust. This melting can be caused by an increase in temperature, a decrease in pressure, or the addition of volatiles. Once magma is generated, it can rise towards the surface through fractures and conduits in the Earth's crust.
