This site provides visual resources that illustrate the concept of isostasy and show how measuring gravity over mountain ranges provides evidence that mountains have deep roots. Visualizations in this collection include images, animations, interactive graphics and photographs. These resources can be integrated into lectures, classes, labs or other activities.

This web site contains a gallery of 3D geologic maps which were created by draping color geologic maps over digital topography. The site features QuickTime Virtual Reality movies that allow the user to spin the 3D geologic map to view it from different perspectives. 3D JPEG images of the maps are available for those users with slower Internet connections. Most 3D maps also have an accompanying topographic ... Full description.

This virtual five-day field mapping project allows students to construct a geological map from data provided by the web site. Students collect geologic, structural, paleontologic, strain and microstructural data observed at specific localities. Students are then able to derive a structural history for the area, including a field map, stereographs, and deformation plots. The site contains photographs ... Full description.

This interactive tutorial is designed to help students visualize geologic features. The site contains many animated block diagrams that show how the surface expressions of dipping layers, folds, igneous intrusions, and faults are related to subsurface structure and cross sections. Blocks may be rotated, eroded, and made partially transparent by moving the mouse. There are also questions and blank ... Full description.

This link takes you to the download page for Tanya Atwater's plate tectonics animations. Users must register before using the site, but it is free of charge. The site contains a series of QuickTime movies illustrates the movement and tectonic history of the Pacific-North America plate from 85 million years ago to present. The movies show the tectonic evolution of California, evolution of the San Andreas ... Full description.

This volume of the Journal of the Virtual Explorer contains 19 papers in both html and pdf formats. Topics include microstructures, rheology, microfabrics, Mohr circles, natural deformation and deformation experiments. Some of the articles contain animated graphics and slide sets.

This Flash animation illustrates continental growth. It shows a convergent boundary where a terrane on a subducting plate is fused to the edge of a continent. Users can stop, play, fast forward and rewind the animation at any time. This visualization is one of several animations in a series developed as a component of Exploring Earth, a website that supports the textbook Earth Science. Full description.

This collection provides a wide array of visual resources and supporting material about plate tectonic movements. Visualizations include simple animations, GIS-based animated maps, paleogeographic maps and globes, and numerous illustrations and photos. This collection is not exhaustive but does represent some of the best sources for teaching. Resources can be incorporated into lectures, labs, or other ... Full description.

This homepage of Steve Reynolds, geology professor at Arizona State University, contains numerous color photographs, 3D imagery and animations, and information about the geology of Arizona. Features of the site include photographs, composite digital and satellite imagery, and topographic images that illustrate various aspects of geology. In order to visualize geology and topography in 3D, there are ... Full description.

This virtual field trip provides an overview of the regional geology of the Lake Baikal area of southern Russia. Satellite imagery and diagrams accompanied by written narrative and thought questions guide students through the process of inferring how geologic movements (faulting) in the area might have been responsible for the formation of the lake. The field trip also provides reinforcement for the ... Full description.
