On the eastern edge of the region, parts of the North and South American plates slide under the Caribbean plate at a rate of about two centimeters per year. Even today, 16 volcanoes are still active over a long period of time. Author: ZDF/Terra X/R. Marel/S. Hillmann/C. Gerisch/A. Kindler/SpiegelTV
In the early 1900s, most geologists thought that Earth's appearance, including the arrangement of the continents, had changed little since its formation. This video segment, adapted from the "Earth Explorer" episode of Discovering Women, describes the impact the theory of plate tectonics has had on
Glaciation during the ice ages caused the sea level to drop. Parts of the limestone reef platforms that form the bedrock of the Bahamas fell dry. Rain penetrated through cracks and dissolved the limestone, creating widely ramified karst caves. Author: ZDF/Terra X/R. Marel/S. Hillmann/C. Gerisch/A.

In this video we will learn how Alfred Wegener proposed a theory in 1912 that the great continents of the Earth had drifted over geological time and were once all joined together in a giant land mass we now call Pangaea. His idea was based on the way present day continents fit neatly together, and

The reaction of a metal at the top of the redox series (zinc) with a metal ion at the bottom of the redox series (copper ions) is represented at the particle level. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The circuit diagrams of the chips are projected onto the plates with light. Almost like a slide. In hundreds of chemical and physical processes, billions of circuits are created on up to 100 chips per plate. Author: ZDF/TerraXpress/GO!Film/Florian Fiedler/Nathan Niedermeier/Jochen Schmidt Transla
Imagine eating a hamburger that is in every way identical to the hamburgers you’re used to eating… except that did not come from an animal. While this may sound like science fiction, cultured meats (also known as lab-grown meat, slaughter-free meat, in-vitro meat, or even clean meat!) may be availab
Learn about underwater volcanoes and the discovery of the erupting deep-ocean volcano West Mata. The video provides students with the opportunity to visualize a phenomenon that is too dangerous and too remote to experience. Students view a visualization of the ocean floor as well as footage that cap
This video segment adapted from NOVA scienceNOW examines a developing theory that might explain a 250-million-year-old "murder mystery." While several possible causes have been considered for the mass extinction that occurred at the end of the Permian period, the scientists featured in the video thi
The theory of how the Grand Canyon was formed is shown in this animation from NOVA, and features rare footage of a phenomenon known as debris flow. CREDITS: https://www.pbslearningmedia.org/credits/ess05.sci.ess.earthsys.canyon/ LICENSE: https://www.pbslearningmedia.org/help/full-license-for-secti
