Educators, students, and anyone interested in brushing up their earth science knowledge may want to check out this resource on the rock cycle created by the Geological Society of London. The main page features a colorful diagram showing an overview of the rock cycle with clickable labels leading to explanations of the cycle's various processes (e.g. weathering, sediment deposition, uplift), with each accompanied by several illustrative photos. Also included here are links to definitions of the three fundamental rock types (sedimentary, igneous, and metamorphic) with more specific examples for each type, as well as some instances of how they are used in everyday life. In addition to navigating via the diagram, the rock processes and rock types can both be accessed using a menu on the upper left. Here readers will also find links to several other notable site features, such as Rocks Around Britain, which contains numerous photos showing evidence of the rock cycle and geologic processes from around the UK. Other linked elements include a Test Your Knowledge section with multiple-choice questions and a helpful Glossary of Terms. Educators should be sure to visit the Teachers' Zone, where they will find background notes, downloadable classroom experiments, and more.
