This volcanic mountain building unit was designed to be used with a college course in physical geography. Subjects covered in this module include: the relationship between plate tectonics and igneous activity, intrusive and extrusive igneous activity, the products of volcanic activity, the relationship between types of volcanoes and magma composition, and a special section devoted to the eruption ...

This is the Student Page of an activity that teaches students how and why magma moves inside volcanoes by injecting colored water into a clear gelatin cast. The Student Page contains the activity preparation instructions and materials list, key words, and a photograph of the experimental setup. There is also an extension activity question that has students predict what will happen when the experiment ... Full description.

This website integrates video footage and information with lesson plans and activities to teach students about volcanoes. Students learn about some of the most dangerous volcanoes, plot locations, research hazards, and assess risks presented by volcanoes. There are lesson plans for each activity with objectives, videos, pre-activities, materials, and discussion questions. There are worksheets, lists, ... Full description.

Volcanoes in the Solar System is a Windows to the Universe Exploratour and provides information and images about shield volcanoes, cinder cones, ash, lava, Venus, Mars, Jupiter, Io, and the Moon. Windows to the Universe is a user-friendly learning system pertaining to the Earth and Space sciences. The objective of this project is to develop an innovative and engaging web site that spans the Earth ... Full description.

This is the homepage of the United States Geological Survey's (USGS) Cascades Volcano Observatory (CVO). The site features news and events, updates on current activity of Cascade Range volcanoes, and information summaries on each of the volcanoes in the range. There are also hazard assessment reports, maps, and a 'Living with Volcanoes' feature that provides general interest information. A set of ... Full description.

Not so long ago, people living near volcanoes had little that might help them to anticipate an eruption. A deep rumble, a puff of smoke, and ash might foreshadow a major volcanic event. Or a volcano might erupt with no warning at all. This interactive feature illustrates some of the types of seismic activity that may preceed an eruption, which modern seismologists are studying in hopes of improving ... Full description.

This site lists the basic types of volcanoes: scoria cone, shield volcano, and stratovolcano. Each is described in terms of shape, composition, and eruption type, and links are available to additional information. Subordinate types listed include fissure eruptions, spatter cones, hornitos, and hydrovolcanic eruptions. The site also explains when a volcano is considered active, dormant, or extinct. ... 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.

Mount St. Helens erupted on May 18, 1980, devastating more than 150 square miles of forest in southwestern Washington state. This animation shows Landsat images of the Mount St. Helens area in 1973, 1983, and 2000, illustrating the destruction and regrowth of the forest. The 1983 image clearly shows the new crater on the northern slope where the eruption occurred, the rivers and lakes covered with ... Full description.

This United States Geological Survey (USGS) on-line publication contains details about the geologic and hydrologic hazards caused by volcanoes, specifically in the U.S. Information and details are provided about hazards such as eruption blasts, volcanic gases, lava and pyroclastic flows, volcano landslides and lahars.
