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 animation illustrates the processes involved in waterfall formation. Related features such as chasms and plunge pools, as well as headward erosion and migration are also portrayed. 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 ... Full description.

This lecture discusses physical and chemical processes that break down rocks and rock debris transportation mechanisms. Physical weathering includes abrasion, fragmentation, frost wedging, and thermal expansion and contraction. Chemical weathering includes solution, oxidation and hydration, and hydrolysis. The lecture notes are supported by images such as photographs, satalite photos, and diagrams ... Full description.

This narrated QuickTime movie shows footage illustrating how waves and currents shape a coastline. Topics discussed include shoreline erosion and deposition, wave energy, swells, swash, bachwash, and longshore drift. This video is from Chapter 19 (The Work of Waves and Wind) of the animations section of the Instructor Companion Site for the Wiley Higher Education textbook (ISBN 0-471-23800-7) Physical ...

CARBONATE 3D reproduces and predicts 3-dimensional stratigraphic geometries and facies in carbonate and mixed carbonate siliciclastic depositional environments. It forward models sedimentary processes over geologic time. Modeled processes include carbonate platform rim and interior production, basinal sediment production, siliciclastic input, subaerial dissolution and erosion, transport and redeposition ... Full description.

This site features a collection of visual resources that can be used to help illustrate the process of physical weathering. Visualizations demonstrate different styles of mechanical weathering and the resulting impact on the landscape. Resources include animations, interactive graphics and photographs showing the effects of physical weathering. These visualizations are suitable for use in an introductory ... Full description.

This Flash animated slide show illustrates the development of a waterfall by demonstrating the way that soft rocks are more quickly eroded downstream than hard rocks. The animation also reveals the way rapids, steep backwalls, plunge pools, overhangs, and gorges develop as well as the way waterfalls retreat up stream. The user can navigate backwards and forwards within the slide show. This is one ... Full description.

This site has links to 5 Flash animations about orbital motion in shallow water, seasonal cycle of a beach, longshore drift of sand, spits and baymouth bars, and coastal straightening. These visualizations are from Chapter 14 (Waves, Beaches, and Coasts) of the animations section of the Online Learning Center for the McGraw-Hill textbook Physical Geology, 9th edition (ISBN: 0072402466) by Plummer, ... Full description.

This site provides students with mathematics self-study material which is embedded within the context of the geosciences. The material consists of many MathHelp "notebooks" covering specific mathematical topics related to a relevant geological context, such as plate velocity or cliff erosion. The notebooks contain explanations, illustrations, and examples. A mathematical glossary is also constantly ... Full description.

This site provides an illustrated lecture from a geochemistry course offered by Dr. Scott Wood at the University of Idaho. Topics include crystal chemistry, ionic substitutions in crystals, weathering (dissolution, redox reactions, acid hydrolysis, and kinetics), the solid products of weathering, and the chemistry of continental waters. The lecture presentation may be downloaded as a PDF document ... Full description.
