Igneous rock forms from the lava of an erupting volcano. This rock is created when molten rock cools and solidifies, either on the surface (extrusive igneous rock) or beneath the Earth's surface (intrusive igneous rock). Examples of igneous rocks include basalt, rhyolite, and granite.
The molten rock that comes out of a volcano is called a magma.
