In this web-based, interactive story, Tutangiaq (Too-tang-geye-ack - nicknamed 2T), a Canada Goose, flies across Alaska looking for his family. As he flies, he tells children about the fascinating 49th state. Children learn how Alaska was purchased from the Russians, and other facts about the state. They can also compare the size of Alaska to other states. 2T takes a flight across the volcanic chain ... Full description.

This show is part of the NASA SCI Files series of instructional programs consisting of broadcast, print, and online elements.- Emphasizing research ... Full description.

This book of 19 essays, written by leading Earth scientists, provides insight into the dynamic processes that shape the Earth. The essays are edited to reach educators, high school students, and the general public and are supported by case studies describing a range of current research projects (including Looking for Life in Antarctica-and Mars, Mapping Mt. Rainer, and Mapping Hot Springs on the Deep ... Full description.

This site is a module for introductory structural geology. The module is web-based and contains text, illustrations, exercises, interactive models, and animations. The module also contains laboratory exercises and a practice exam. Topics include stress and strain, faults, folds, and geologic maps. This site would be useful for teachers looking for interactive teaching tools, or could be used by students ... Full description.

This site contains visualizations for stress and strain analysis. These visualizations allow the student to create and view detailed illustrations and animations of the mathematics of stress and strain. Topics include lithostatic stress, the stress tensor, the Mohr Circle of stress, pure and simple shear, the principle strain directions, incremental versus finite strains, strain path dependencies, ... Full description.

This page has several animated cross sections which illustrate common structural models. The animations illustrate the development of fault bend folds, duplexes, fault propagation folds, and normal faults. Full description.

This site, which accompanies an introductory structural geology class at the University of Leeds, UK, contains information on faults. Topics include normal faults, thrust faults, strike-slip faults, faults and stress, and soft-linked fault systems. The site features explanations of the three basic types of faults with informative diagrams and a photo gallery. Full description.

This site features a series of four Macromedia Flash animations. These simulations illustrate the formation of basic geologic structures, including normal faults, thrust faults, strike-slip faults and various styles of folds. The animations were designed to complement the chapter on geologic structures in "Physical Geology" by Plummer, McGeary and Carlson. Full description.

This website, from the 1998 PBS "Savage Earth" series, shows seismic waves from an earthquake that took place in Bolivia in 1994. The animation illustrates the way the earth's surface, core/mantle boundary and inner/outer core boundary reflect and deflect P- and S-waves. Full description.
