There is almost unimaginable energy -- both thermal and mechanical -- stored within the Earth. Some
of this energy is released occasionally as two sections of the crust suddenly release and slide against
each other. The result of this motion is called an earthquake, and such an event can be devastating
to life and property. This study set presents 8 specimens of rocks typically associated with earthquakes,
plate boundaries and tectonic sites.
The samples are displayed in a 5 by 7.5 inch snap-close plastic case, and each set includes a
detailed information sheet.
