Magma inside Earth is under a lot of pressure, so it will tend to flow toward the lower pressure at the surface. Additionally, gasses dissolved in the magma bubble out of the magma as it approaches the surface, like bubbles from a freshly opened can of soda. As the gases expand they forces some of the molten rock out of the volcanic vent.
