Igneous rock is formed by the cooling and solidification of molten Earth materials. Igneous rock forms when magma or lava cools. If igneous rock forms above ground after a volcanic eruption, it cools quickly, forming extrusive igneous rock, such as obsidian which is a naturally occurring volcanic glass.
