Geological Processes DVD
In 1989, Northern California felt the effects of an earthquake that measured 7.0 on the Richter scale and #151; powerful evidence of the Earth's inner turmoil. Segments cover earthquakes, types of rock, identification of minerals, and plate tectonics.
- THE ROCK CYCLE: Takes students around the United States to find examples of the three types of rock: igneous, metamorphic, and sedimentary.
- EARTHQUAKES: Discusses how scientists measure the magnitude of earthquakes and the tools they use to predict seismic activity.
- HOW TO IDENTIFY MINERALS: Travels with a geologist who explains how a rock found in Namibia is identical to one found in Argentina.
- PLATE TECTONICS: Explains why the surface of the Earth looks the way it does as a result of the activity that goes on below it.
