Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from magma erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin.he sub-family of rocks that form from volcanic lava are called igneous volcanic rocks (to differentiate them from igneous rocks that form from magma below the surface, called igneous plutonic rocks). The lavas of different volcanoes, when cooled and hardened, differ much in their appearance and composition.
Igneous rocks are formed around hot spots when there is an increase  in temperature, a decrease in pressure, or a change in composition.  Igneous rock is formed through the â¦ cooling and solidification of  magma or lava.ntrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes â¦ lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.
