shows common rock-forming processes. See magma crystallize to form igneous rock, rock erosion to create sediment, transportation of sediment, deposition of sediment to create sedimentary rock, and the creation of a metamorphic rock. Animations can be paused and rewound to stress important points. (Carleton College, National Science Foundation)
