This beginning geophysics course is designed for geology majors. It provides a relatively rigorous and homework-intensive overview of the structure and evolution of the Earth and terrestrial planets, at a level higher than a descriptive geology class, but lower than the standard introduction to geophysics for seniors or first year graduate students. Demonstrations are presented with links to a variety ... Full description.

Athro, Limited is a for-profit corporation that publishes high school and college level biology, earth science, and geology course supplements and independent learning materials on the Web. This site provides instruction in interpreting the order of events in three hypothetical and one real geological section. For each section there is a list of events and an animation of the history of the section ... Full description.

This United States Geological Survey (USGS) publication discusses the San Andreas Fault in California; specifically what has caused the fault, where it is located, surface features that characterize it, and movement that has occurred. General earthquake information includes an explanation of what earthquakes are, and earthquake magnitude versus intensity. Earthquakes that have occurred along the fault ... Full description.

This on-line book, published by the United States Geological Survey (USGS), discusses the use of fossils in determining the age of rocks. The publication covers how to place events in correct temporal order, a description of the geologic time scale, the use of fossils to indicate rock ages, the law of fossil succession, index fossils, and radioactive dating. Full description.

This on-line book, published by the United States Geological Survey (USGS), covers the 1980 eruption of Mount St. Helens in Washington state. There is a discussion of the events leading up to the eruption, as well as an explanation of the mountain's volcanic history. Immediate effects are covered, including the ash falls, pyroclastic flows, and debris. Post-eruption topics include subsequent activity ... Full description.

This on-line project is part of the Center for Improved Engineering and Science Education (CIESE) program. As they complete this series of lessons, students will use real-time data to solve a problem, study the correlation between earthquakes and tectonic plates, and determine whether or not there is a relationship between volcanoes and plate boundaries. Musical Plates has four Core Activities that ... Full description.

Scientists in Action provides news about natural scientists and what they do, including: how scientists must react to rockfalls and earthquakes; spy plane modification by NASA to gather data to help forecast brush fires and spot toxic waste; frog malformation and population decrease; the 'Geologists in the Parks' program, which involves new earth scientists in helping National Park staff understand ... Full description.

This reference provides detailed information and activities related to the geology of Yosemite National Park. The introduction provides a history of ideas on Yosemite's origin. An overview describes the geologic history of the Sierra Nevada Mountains. An interactive timeline is featured to provide users with a temporal reference on park history. For students, there is a field journal with interactive ... Full description.

The Virtual Courseware Project produces interactive online simulations to help enhance the learning and teaching of geology and other Earth and environmental science topics. Each lab provides a brief introduction to the topic and a quiz to assess understanding of the material. Materials include an activity in which seismic waves are used to determine the magnitude of an earthquake and to locate its ... Full description.

This Classroom of the Future (COTF) website focuses on Earth science for kindergarten through 4th grade students. Topics covered include biomes (forest, desert, grassland, aquatic, tundra, chapparal), weather (seasons and climate), remote sensing (sonar and radar), and the Earth system (spheres and cycles). A teacher's section contains online and hands-on activities, and topic overviews. Full description.
