Igneous rock is the type of rock most commonly formed from volcanoes. igneous rocks may be formed from the magma underground, or form after the magma has ejected into the air. Underground, they can be formed when magma (molten rock) is trapped in small pockets and cools slowly over time. Above ground, igneous rocks are formed as the lava cools.
Metamorphic rocks can be the result of volcanic activity, but they are not formed directly from volcanoes. Metamorphic rocks are the result of intense heat or extreme pressure transforming either sedimentary or igneous rocks, and these stresses can come from volcanic action, though that is not always the case.
