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.
The magma that forms igneous rock beneath the surface of the earth can take thousands of years to cool. Quickly cooling rock, often extrusive lava that comes from volcanoes or fissures in the Earth's surface has small crystals and may be quite smooth, such as the volcanic obsidian rock.he magma that forms igneous rock beneath the surface of the earth can take thousands of years to cool.
