Investigation 5: Earthquakes, Volcanoes, and Mountains

To learn more about the nature of earthquakes, visit the following web sites:

Savage Earth, Restless Planet: Earthquakes, PBS
This web site accompanies the PBS Series Savage Earth and includes background information on the connection between faults, earthquakes, and seismic waves.

Virtual Courseware: Earthquake, Virtual Courseware
This site contains deatailed pictures of earthquake damage. There are also activies such as travel time and epicenter to use along with a demonstration.

To learn more about earthquake and plate movement, visit the following web sites:

Earthquakes, Faults, Plate Tectonics, Earth Structure, USGS
Read answers to some commonly asked questions about earthquakes, faults, and plate tectonics. In some cases, the answers include links for further information.

Earthquakes and Plate Tectonics, USGS Earthquakes Hazards Program
This article aims to explain why earthquakes happen along plate boundaries, and often in the same area as volcanoes or mountain ranges.

Plate Tectonics, the Cause of Earthquakes, Nevada Seismological Laboratory
Review a technical explanation with images of different types of faults, spreading centers, or collision zones in connection to earthquakes.

To learn more about the nature of volcanoes, visit the following web sites:

Savage Earth, Mountains of Fire, PBS
This web site accompanies another portion of the documentary, Savage Earth, with general information about different types of volcanoes, the location of volcanoes, and different types of volcanic eruptions.

Volcanic Gases, USGS Volcano Hazards Fact Sheet
Discusses why volcanic gases are important to study, how geologists study volcanic gases, and what they have learned.

To learn more about volcanoes and plate movement, visit the following web sites:

Location of Volcanoes, NASA Classroom of the Future
Find out more about how and why volcanoes form along plate boundaries or above hot spots. Note the links to other related pages about plate tectonics and heat flow or looking inside the Earth.

To learn more about the association of earthquakes and volcanoes, visit the following web sites:
