With HD footage from all over the world, this program shows students all the various types of landforms found on our planet. Animation segments demonstrate how land formations are created by movement of the earth's plates, volcanoes,...

Geology is the study of the Earth itself. But contrary to popular belief, geologists don't just look at rocks all day. Of course rocks are important to study, but geologists also study earthquakes, volcanoes, glaciers, and the structure...

At 8,850 meters above sea level, Qomolangma, also known as Mount Everest, has the highest altitude on the planet. But how did this towering formation get so tall? Michele Koppes peers deep into our planet's crust, where continental...

In this video Paul Andersen explains how plate tectonics explains the large-scale system interactions on our planet. Large plates float on the mantle and interact to form the major landforms on the planet. Evidence for plate tectonics...

In some places, the rocks below the Great Unconformity are about 1.2 billion years older than those above it. This missing chapter in Earth’s history might be linked to a fracturing supercontinent, out-of-control glaciers, and maybe the...
