Igneous rocks form when magma (molten rock) cools and becomes solid. If this happens underground, the magma solidifies slowly, giving large crystals time to form. The magma becomes a hard rock, such as granite. Igneous rocks can also form on the Earth's surface when lava escapes from a volcano and solidifies quickly.
