The Geological Society of London (GSL) offers a pair of online resources for learning about key geoscience topics. Electronic map-based resources are the focus of GSL’s Plate Tectonics page (http://www.geolsoc.org.uk/Plate-Tectonics). In addition, a site is being launched to accompany GSL’s Rock Cycle online module (http://www.geolsoc.org.uk/rockcycle).
