Is volcanic rock only igneous?
Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
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.
