Obsidian is a type of volcanic glass that forms when lava cools rapidly without crystal growth. It is not formed under the Earth's crust, but rather on the surface during volcanic eruptions. The rapid cooling process prevents the formation of crystals, resulting in the smooth, glassy texture characteristic of obsidian.
