Magma develops within the mantle or crust when the temperature-pressure conditions favor the molten state. Magma rises toward the Earth's surface when it is less dense than the surrounding rock and when a structural zone allows movement.
Most magma that reaches the surface in volcanic eruptions comes from a part of Earth's mantle called the asthenosphere. The asthenosphere is a layer of solid rock that is near its melting point.Turning this solid rock into liquid magma means changing its temperature, pressure, and water content. Try your hand at melting rock to create magma. The first thing to try changing is the temperature.Your rock is a toasty 1,500 degrees Celsius, but it's still solid.
