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
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
Around the world, Bosch engineers file 19 patent applications every working day. One of them is Gökce Cetin Görbuz from Turkey. Learn more about how the innovations of Bosch inventors make our lives easier, better -- and often safer: http://www.bosch.com/en/com/boschglobal/inventors_for_life/invent

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
Due to the displacement of tectonic plates, several geological seams were created at the same time when unfolding. The friction of the rock layers generates so much heat that the heated water deep down is pushed up to the surface. Author: ZDF/Terra X/Fascination Earth/C. Götz-Sobel/O. Rötz/M. Zimme
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
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 rock plates of the earth's crust are constantly in motion. They can get caught and build up enormous tension. If this tension is released suddenly, the plates continue to slide. The earth shakes. Author: ZDF/Terra X/Julia Kammerer/Martin Schaaf/Maximilian Mohr Translation and dubbing: alugha

Earth is a complex, evolving body characterized by ceaseless change. To understand Earth on a global scale means using a scientific approach to consider how Earth's component parts and their interactions have evolved, how they function, and how they may be expected to further evolve over time.
