Coastal Processess (39:30) Fantastic aerial shots and graphics help explain how coastal landforms are created by the processes of erosion, transportation, deposition weathering and mass movement. Explore the impact of geology and see examples of discordant and concordant coastlines. The program takes a systems approach and explores the role of constructive and destructive waves, sediment sources, and cells.
Mountains and Mountain-Building Processes (23:02) We think of mountains as eternal, but they are evidence of our planet’s surface bending and buckling like cardboard. Examining Earth’s mountain-building processes in detail, this program also studies the weathering, erosion, and mass wasting by which mountains are worn down. Viewers gain insight into the basic factors that underlie volcanic activity, the various types of geological faults, and the tectonic processes in which oceanic and lithospheric plates collide, separate, or slip past each other, resulting in dramatic physical changes. Eye-catching graphics as well as live-action footage from the Alps, Andes, Cascades, Rockies, and Himalayas help illustrate concepts.
Plate Tectonics (24:41) Studies of our planet’s crust, or lithosphere, suggest that it’s not a single solid layer at all. This video illustrates the process of scientific inquiry by studying the evolution of our understanding of plate tectonics, the dynamics of those ever-shifting slabs of earth we call solid ground. Beginning with Alfred Wegener’s hypothesis of continental drift, the program discusses major and minor plates, types of plate boundaries, and the concepts of spreading and subduction. Earthquakes and volcanoes are also addressed.
Plate Tectonics: Secrets of the Deep (57:12) Viewed from space, one of the remarkable features of our planet is that it has continents and oceans. The changing pattern of the continents and oceans is a very important characteristic of the earth, and the discovery of how this movement occurs is one of the most exciting scientific stories of modern times. The key to this understanding lay not in the continents at all, but in the oceans.
River Processes (31:16) This program provide students with memorable examples of potholes, rapids, waterfalls, gorges, meanders, braiding, flood plains and deltas. The case studies, along with the detailed graphics provided, explain the fluvial processes of erosion, transportation and deposition and explore how they change throughout a river's course. The process and impact of rejuvenation is also explored through the use of specific examples.
The Rock Cycle (20:37) In this program a young environmental engineer takes viewers into the field for an in-depth look at the rock cycle and the geologic processes that occur within Earth’s core, mantle, and crust. Using dynamic graphics to illustrate essential terms, the video covers the formation of igneous, sedimentary, and metamorphic rocks; their physical and chemical properties; subgroups and examples of each; and where they fit in to the rock cycle. The video also provides an informative overview of minerals and the methods used to classify them.

Earth's Rock Cycle (2:13) Rocks are recycled from molten magma to igneous and crystal rock. Once above ground, rocks are worn down into sediment and sedimentary rock. Through the process of metamorphism, rocks can become magma again.
