These lecture notes provide information on magma production, types of igneous rocks, and volcanic processes. Other subjects include active volcanoes, historical eruptions, volcano structure and formation, classification of volcanoes, controls on eruptive style, and volcanic hazards. The lecture notes feature many diagrams and photographs, as well as links to further information. This resource is part ... Full description.

This resource defines and describes composite volcanoes, stratovolcanoes, subduction-zone volcanoes and composite cones. The information is from different sources and therefore the site gives a broad picture of these forms. The shape of the volcano is described as a function of the type and frequency of eruption and its proximity to plate boundaries. Full description.

This video segment shows how scientists collaborate to collect and chemically analyze samples of molten lava as part of their quest to learn more about how volcanoes work. Working at Kilauea volcano, scientists collect samples of lava before it has a chance to cool so they can study the chemical properties it had when it was deep within Earth's interior. The samples are sent to a laboratory where ... Full description.

This article, entitled Mountains of Fire, describes the relationship between the types of volcanic activity and plate movement and the connection between types of volcanoes and how they erupt. The article is supported by a video of an erupting volcano, a photograph of an eruption and an animation depicting pyroclastic flow and the formation of a composite volcano. It is also supported by three sidebars, ... Full description.

This interactive slide show provides accounts of eight of history's most deadly volcanic eruptions. These eruptions are from both ancient and modern times, and include such volcanos as Mount Vesuvius, Tambora, Krakatau, Nevado del Ruiz, and Mount Pinatubo. Each slide features an illustration from the event, a written description with the name of the volcano, date, number of casualties, an account ... Full description.

This Thinkquest offers an encyclopedic look at plate tectonics and volcanoes. Reference sections describe the interior of the Earth, continental drift, sea floor spreading, subduction, volcano types and eruptions, lava flow, and famous volcanoes. Lesson plans cover the internal structure of Earth, plate tectonic theory, and how volcanic eruptions and earthquakes affect the human environment. There ... Full description.

Aerosol index over Central America from March 27, 1982 through April 14, 1982 as measured by the Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) Full description.

This educational resource describes the science behind volcanoes and volcanic processes. Topics include volcanic environments, volcano landforms, eruption dynamics, eruption products, eruption types, historical eruptions, and planetary volcanism. There are two animations, over 250 images, eight interactive tests, and a volcano crossword puzzle. Full description.

For hundreds of thousands of years, lava flows have created intricate patterns on the slopes of Hawaii's Mauna Loa volcano. Until the mid-1970s, it was impossible to know when each of the flows occurred. However, as this video segment describes, a researcher has discovered a way to date the flows by determining the age of carbonized plant remains that they covered. The segment is four minutes thirty-three ... Full description.

This lesson presents volcanoes through the making of volcano models. While students are constructing their physical representations of volcanoes, they will be filled with questions about volcanoes as well as how to build their models. This process will provide students with a tangible reference for learning about volcanoes and give them a chance to problem-solve as they build their models. Students ... Full description.
