Science: How Volcanoes Work

"This website is an educational resource that describes the science behind volcanoes and volcanic processes. Each section in the menu builds upon previous sections. For users who lack fundamental knowledge of volcanological principles and terms, it is best to proceed through the website in a progressive manner. More advanced users will find each section self-contained and can navigate through the website as their interest dictates." - from the website. <http://www.geology.sdsu.edu/how_volcanoes_work/>
