Lava

An eruption is like opening a can of shaken soda. Bubbles of gas seperate from the liquid and force the liquid out. The material that erupts from a volcano is called lava. As lava cools and hardens, it becomes igneous rock. That's brand-new crust! If the rock builds to great heights, a moutain or island forms.
