Students use geologic fault maps of the San Francisco Bay Area to find relationships between tectonic plate fault lines and landscape features, topographic features, and epicenters of past earthquakes.

The San Andrea is an active fault zone, marked by frequent earthquake activity. The crust southwest of this strike-slip fault (including Los Angeles) is sliding to the northwest relative to the other side. It is possible to estimate the...

Students work in small groups to use a physical model, the earthquake machine, to examine the occurrence of earthquakes and the inputs and outputs of fault systems.

Students examine images of faults and folds, then experiment with two models to collect evidence to determine how the structures formed.
