In this activity, students plot daily earthquake locations on a world map. They will understand that earthquakes are not randomly distributed around the Earth, but occur at plate interfaces, and learn to identify the 'Ring of Fire' around the Pacific Basin. Full description.

This page consists of two maps of the world, showing how earthquakes define the boundaries of tectonic plates. Volcanoes are also distributed at plate boundaries (the "Ring of Fire" in the Pacific) and at oceanic ridges. It is part of the U.S. Geological Survey's Cascades Volcano Observatory website, which features written material, images, maps, and links to related topics. Full description.

Part of Prentice Hall's Planet Diary, this computer activity covers volcanic activity. Students research the most recent volcanic activity and the locations and names of each volcano. They then find out which tectonic plates the volcanoes are located on or if they are hot spots, and if any are part of the Ring of Fire. Full description.

This information on the two major types of plate interaction and the resulting features discusses the Mid Atlantic Ridge and the mid-ocean ridges in connection with divergence and ocean trenches and connects the Pacific Ring of Fire to the concept of subduction. Volcanic activity as a result of subduction is also covered. The site also features links to goals, objectives, and materials for a hands-on ... Full description.

Follow ocean explorations in near real-time, learn about ocean exploration technologies, observe remote marine flora and fauna in the multimedia gallery, review NOAA's 200-year history of ocean exploration, and discover additional NOAA resources in a virtual library.

This portal provides links to an extensive list of volcano-related websites for the United States and around the world. Users can access articles, maps, glossaries, webcams, a dictionary of volcanoes, and many other resources. Full description.

VolcanoWorld has been a leading source of information about volcanoes since January 1995. Each year VW serves about 4 million different users, including grade school kids, teachers, college students, professors, researchers, government scientists and the general public. The homepage includes information on current eruptions, volcano descriptions, learning and adventures on volcanoes. Full description.

In this Web-based, interactive story, Tutangiaq (Too-tang-geye-ack - nicknamed 2T), a Canada Goose, flies across Alaska looking for his family. As he flies, he tells students about the 49th state. Students learn several facts about the state, including how Alaska was purchased from the Russians,. They can also compare the size of Alaska to other states. 2T takes a flight across the volcanic chain ... Full description.

This resource presents information about using living things like trees and coral reefs and everyday occurrences like snowfalls to look at what has happened in past climates in order to understand what is happening today, or what might happen in the future. Scientists who do this are called paleoclimatologists. Some of the things that can be learned from tree rings include insect outbreaks, glacial ... Full description.

The Jet Propulsion Laboratory's (JPL) homepage provides links to spacecraft and mission information, imagery, news articles, events, features, and public services. Users can access articles and imagery from the Mars Rover and Cassini missions, images from the Spitzer Space Telescope, and an El Nino/La Nina Watch. Full description.
