How Volcanoes Work was constructed and is maintained by Dr. Vic Camp from San Diego State University's Department of Geological Sciences. The site takes a comprehensive look into every aspect of volcanic formations and eruptions, including historical eruptions (Mt. St. Helens) and volcanism on other planets. Well written and designed, this site offers excellent illustrations, photographs, and...

Created by the Earth and Ocean Sciences Department at the University of British Columbia, this module on magma mixing is based on ideas and theories taken from papers authored by Stephen Blake and Gregory N. Ivey. A short movie, which can be viewed at the site, shows a lab experiment where two different magmas are mixed to form a hybrid magma. Users can then peruse information (including...

If you are having difficulty remembering the details of the Earth's geological structure or the nature of major minerals and rock types, you can consult this excellent introductory course offered as part of MIT's OpenCourseWare initiative. The materials are drawn from Professors Perron and Jagoutz's 2011 "Introduction to Geology" course, and they include a number of lecture notes, available for...

Many people might know about the life cycle of a rock, but it can be a process that is hard to understand without a handy visual aid. Just such a series of aids can be found right here, courtesy of Mark Francek of Central Michigan University. These rock cycle animations display some of the most common rock-forming processes, including the crystallization of magma to form igneous rock, rock erosion...
