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.
1 The mantle is extremely hot, but for the most part, it stays in solid form because the pressure deep inside the planet is so great that the material can't melt. 2  In certain circumstances, however, the mantle material does melt, forming magma that makes its way through the outer crust.
