U.S. Geological Survey
Visit the Listening to Earthquakes interactive activity at the U.S. Geological Survey site. As the waves from an earthquake travel through the ground, the energy from the earthquake decreases. Do earthquakes lose energy faster through solid granite or chewed up rocks?

University of California at Santa Barbara
This site provides information about the science of earthquakes. Watch the Introduction to Elastic Rebound Animation to watch a simulation of the effects of stress building up along a fault zone. How is the road affected by the earthquake's action?

University of Delaware
Visit the Voyage to the Deep site, part of the University of Delaware's College of Marine Studies to explore hydrothermal vents. Watch the video to get a closer look at these deep-sea phenomenon. What is a black smoker?

NOVA Online
Into the Abyss looks at the undersea environment that exists around hydrothermal vents. More than 300 species of animals that had never been seen before were discovered in the last two decades as scientists have learned more about life around a deep sea vent. Watch the videos to see what life looks like deep in the ocean. What are some of the extreme temperatures found in these environments?l
