Hot magma, melted rock below Earth's crust, rises and collects in a magma chamber deep below the surface. If the magma flows through a conduit up to a vent on the surface, then it may cause an eruption and form a volcano. Gases, lava, and pyroclastic material are erupted from volcanic vents. The mountain that forms from layers of lava and tephra is called a volcano. The word volcano comes from the name of a Roman god, Vulcan, who was the god of fire.
