Great resource for learning all about tornadoes. Find out how they are formed, how they erupt, the different types, and notable volcanic eruptions. Also includes safety tips, animations, and activities.

Site from the U.S. Geological Survey provides a brief list of volcano terminology including descriptions as well as links to major menus.

Basic information about the 1857 "Fort Tejon" Earthquake, along with comparison to other quakes, location of the epicenter, and faults involved.

Describes details of the earthquake of November 29, 1975 Kalapana in Hawaii, the tsunami, and the eruption of the volcano Kilauea as a result of the earthquake.

Learn how seismic tomography imaging helps scientists understand the formation of the Earth's interior.

A 260-page unit of activities on earthquakes. Covers what they are, their cause, why and where they occur, their impact on the Earth, how they are measured, and safety and survival. Includes worksheets and has a glossary at the end.

An earth science collection where learners can explore earthquakes, volcanoes, and more natural phenomena. The collection uses videos and interactive activities to investigate our dynamic planet and earth systems.

A suite of lessons focusing on all aspects of earthquakes. Inquiry-based exploration of earthquakes includes measuring seismic waves, predicting earthquakes, investigating magnitude and intensity, mapping fault lines, and evaluating...

Explore the biosphere, zoom in on some unique ecosystems, and learn how activity in the Solar System and plate tectonics can affect the climate and life on the planet.

Multi-lesson activity where learners will work with data from a seismic wave model in a GIS (geographic information system) program. They will examine maps, select data, and produce graphs to explore variations in seismic wave velocities...

Learn what the Mid-Atlantic Ridge is, how it was formed in the Triassic Period, the volcanic activity that takes place there, and the benefits and negative impact of this activity.

Learners learn about the structure of the earth and how an earthquake happens. In one activity, students make a model of the earth including all of its layers. In a teacher-led demonstration, learners learn about continental drift. In...

Build an instrument for measuring movement to learn about how scientists measure the Earth's movement with a seismometer.

Earth Science teachers will combine field observations with the information given in the classroom to interpret the geologic history of Canyon de Chelly, Arizona.

Students construct a model that demonstrates how a block of rock is extended by a normal fault.

Through five lessons, students are introduced to all facets of the rock cycle. Topics include rock and mineral types, material stresses and weathering, geologic time and fossil formation, the Earth's crust and tectonic plates, and soil...

This site features several links to tsunami relief sites. Students and teachers can access information about the tsunami relief efforts through these resources.
