When it reaches the surface, a volcano is formed. The magma flows out as lava, sometimes explosively. The majority of the world's volcanoes are associated with subduction zones. Since subduction zones represent plate margins, volcanoes tent to occur in lines, like the Cascade Range volcanoes or those on the Aleutian Peninsula. Once in a great while, a new volcano will form. This usually happens when an active underwater volcano produces enough lava to break the surface, such as Surtsey in Iceland in 1963.
