Composite volcano magma contains more silica, SiO 2, than that of a shield volcano and is therefore stickier (more viscous).This stickiness plugs up the volcano, causing pressure to build-up. The result is an explosive, dangerous eruption.omposite volcano magma contains more silica, SiO 2, than that of a shield volcano and is therefore stickier (more viscous).
