This is a nine-part series of videos titled “Earthquake Country Los Angeles” that discusses plate tectonics, faults, the Northridge earthquake and seimic waves, as well as ways we can minimize the damage created by earthquakes.

From site:  Subduction Construction is an educational game in which players examine Franciscan Complex rocks of the Golden Gate Headlands to place them in the context of the Cretaceous Period subduction zone.

Players use high-quality, digital images of rocks from seven collection sites of the Golden Gate Headlands to record geologic data “in the field.” Then they bring their rock samples to the lab and perform tests to complete the identification of the rock samples.

Players are ready to visit the subduction zone and begin “construction” once they accurately identify the rock samples. Successful placement of all the rocks starts an animation of the subduction zone, which helps players visualize the tectonic movements that formed much of the dramatic geologic scenery of the San Francisco Bay Area.

The Global Volcanism program provides students an interactive world map of volcanic activity. The accompanying database of volcanoes is searchable by name, type, features, country, rock type, and more. View time-lapsed animations of volcanic and seismic activity since 1960. The site includes links to numerous other resources

From site:  Why do volcanoes erupt? How are rocks made and destroyed? Why do rivers wiggle back and forth? What sorts of animals roamed the Earth long ago? These questions and many more can be answered if we know a little about GEOLOGY! That’s the study of the Earth.
