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.
What else can I help you with?
Are all rocks formed by volcanoes?
no not all rocks are formed by volcanoes because what about sedimentary rocks which are the rocks formed over a long period of time by little pieces of sand and rock etc. by wind and water
What type of rocks are found in Hawaii Volcanoes National Park?

Can igneous rocks form inside and outside of volcanoes?
yes
What are types of rocks formed by volcanoes?
Three different types of volcanoes are 1) Shield volcanoes; they are large mountains with gentle slopes. 2) Cinder cones volcanoes; they are small volcanoes made of hardened lava chunks called cinders. And the last one is 3) composite volcanoes; they are medium sized mountains made up of layers of lava that alternates with cinders. That is it.
What types of rocks are near active volcanoes and why?
When lava cools, it forms what is known as an extrusive igneous rock. Volcanoes are also associated with alteration from heat and fluids. Therefore you would expect to find extrusive rocks as well as altered rocks.
Are plutonic rocks igneous rocks that hardened on top of volcanoes?
No. Plutonic rocks are igneous rocks that hardened underground. Rocks that form on volcanoes are volcanic rocks.
How are volcanoes important in the formation of rocks?
Because the lava from volcanoes form igneous rocks
