Exploring Earth This collection of learning modules uses animations, simulations, interactive graphics, and other features to illustrate earth science concepts such as rocks, plate tectonics, volcanoes, earthquakes, glaciers, oceans, and the solar system. This site was meant to accompany a textbook (purchase required; site search requires textbook codes), but it can also be used as a stand-alone resource.
