Is a volcano a igneous rock?

Not necessarily. Igneous rock can be divided into two broad categories: intrusive rock and extrusive rock. Intrusive rock forms when molten rock cools and solidifies underground, so no volcanic activity is necessary. Extrusive rock forms above ground from molten rock that erupts from a volcano.
