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.
As magma migrates away from the melting zone, it slowly cools off. As it does, more and more solid mineral grains crystallize until eventually all of the melt is gone. Sometimes, magma will get close enough to the surface to feed volcanic eruptions. But most of the time, the magma cools and crystallizes below ground, forming intrusive igneous rocks. Huge masses of igneous rocks are called 'plutons.' When plutons are uplifted during tectonic plate collisions, then eroded by wind and water and ice, they are revealed to us in the rugged topography of the world's mountain ranges.
