A volcano is an opening in the Earth’s surface that allows lava, hot gas, rock fragments and ash to explode from below. They are usually located at the edges of tectonic plates, where the plates are either shifting apart from each other, or moving toward each other. To view an active volcano is both exciting and terrifying. But no worries, this volcano tour will be conducted from the safety of your computer chair.

Annenberg Media: Volcanoes Can We Predict Volcano Eruptions?5 stars

"As the world's population grows, more and more people are living in potentially dangerous volcanic areas. Volcanic eruptions continue - as they have throughout most of geologic time - posing ever-greater threats to life and property." Explore how volcanoes are formed, why they erupt, and how scientists are getting better at spotting the warning signs of an impending eruption. Be sure to watch the video clips scattered throughout the site.

Hawaii Space Grant: Volcanology5 stars

These five hands-on volcano activities for the classroom were created by teachers and librarians during a summer workshop at the University of Hawaii in 1994. Each activity includes printable instructions for both teachers and students. The activities include making a gelatin volcano to demonstrate how magma moves inside a volcano, and making cake batter lava to explain the structures that form as lava flows across a variety of landscapes.

San Diego State University: How Volcanoes Work4 stars

Sponsored by NASA and Project ALERT (Augmented Learning Environment and Renewable Teaching), How Volcanoes Work is an educational resource for high school and university students. Because the material builds on itself, it is recommended that visitors start at the beginning, and traverse through the site sequentially. Each of the six sections concludes with a self-scoring quiz, and for those up for the challenge, there's the Spatter Patter Crossword. What's a three-letter word for "finest pyroclast"?

USGS: Volcanoes by Robert I. Tilling4 stars

"Geologists generally group volcanoes into four main kinds – cinder cones, composite volcanoes, shield volcanoes, and lava domes. Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent." This online booklet, published by the U.S. Geological Survey, is an outstanding introduction to the geology of volcanos. A print version is also available via snail mail request.

Volcano World5 stars

Volcano World is an educational outreach project of the North Dakota and Oregon Space Grant Consortia. Best clicks are the 101 most frequently asked questions ("What are the different types of lava flows and how do they form?"), the worldwide volcano index, volcanic glossary, and interviews with eight volcanologists. "They [volcanoes] can be hot, smelly, and dangerous, why would someone want to work on volcanoes?" Kids Door houses a gallery of kids artwork and several volcano-themed games, including an interactive crossword.
