United States Geological Survey geologist, Angie Diefenbach, describes how she uses GIS (Geographic Information Systems) software to study volcanic erupts and their impacts on society.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on the geological features of caves. Part of the Science Video Vocab Series.
Capulin Volcano National Monument was born of fire and forces continually reshaping its surface. It’s a dramatic landscape of mountains, plains, and sky and provides access to some of nature’s most awe-inspiring work in New Mexico.
Surveys soil's formation, composition, properties, types, and movement. Also identifies the five major plant communities: tundra, forests, scrublands, grasslands, and deserts. The connection between soils and vegetation affects where people live.
Host Lisa Van Pay meets researchers who study life in caves. The team explores Snowy River, a bright white crystalline formation found deep within Fort Stanton Cave in New Mexico, finding life and energy in unexpected places.
Harmony Colella, a postdoctoral research fellow from Arizona State University, explains how experiencing an earthquake as a child in Southern California inspired her to become a geophysicist. Part of the “EarthScope Chronicles” series.
How are rocks formed? Do they change over time? Students explore the world of rocks and minerals. They also learn how to identify common minerals and properties of rocks. Part of the "Way Cool Science" series.
Rocks, a naturally formed material that covers the earth, are classified by their origin. Discusses rocks' composition, three types (igneous, sedimentary, and metamorphic), how they are formed, and how they are changed. The rock cycle is a slow, ongoing process.
Volcanoes and earthquakes! Geysers and boiling mud! Natural forces like these have been working for millions of years, changing the surface of the earth. Examines the layers of earth, a history of continental drift, plate tectonics, and other phenomena at work on our planet.
Uses trilobite fossils as an example to illustrate the challenges scientists face in understanding the prehistoric world and its place in time. Examines fossil sites in Australia, discusses how fossils are formed, and tells how a fossil's world is recreated.
Presents a brief history of the United States Geological Survey (USGS) as well as the significance of its work and mission in today’s world.
Photographers and scientists try to explain their fascination with volcanoes and earthquakes. Focuses not on the geological causes, but on how and why these phenomena are photographed and studied. Uses actual footage and closeups for impact. James Earl Jones narrates.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the geography of deserts. Part of the Science Video Vocab series.
While it may not always seem possible, Earth is continually changing. Students gain insight into geological processes such as the formation of land, erosion, and volcanic eruptions. Other Earth processes are also investigated.
Learn how scientists are attempting to enhance apples' defenses through genetic engineering. Viewers learn why it is important for organisms to have a wide variety of genes. Part of "The Botany of Desire" series.
What is a seismic wave? Which of the four types is most destructive? Discover the science behind earthquakes with this animated video.
California’s Pinnacles National Monument is America’s newest National Park. The monument gets its name from its spires and rock formations. It is also home to the California condor, rare chaparral vegetation and carpets of wildflowers.
