Water covers most of our Earth’s surface area. In this program, we’ll discuss the characteristics of the sea and its impact on climates and coast lines. Topics include: Marine Plants, Sea Water Characteristics, Ocean Currents, Sea Water Temperature, Wave and Tide Formation, Tsunamis, The Sea Bed, and Underwater Gas and Petroleum Deposits.

This live-action video program is about ectotherms. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated graphics and labels. Viewers will see and hear the word used in a variety of contexts providing students with a model for how to appropriately use the word. Related words are also used and reinforced with visuals and text....

Looks at the earliest events on Earth, telling how the planet was formed and how its structure developed, continents arose and broke apart, and living things began to appear.

In January 1700, a massive subduction earthquake devastated a portion of the Oregon-Washington-British Columbia coast. Ten years of research and increased seismic activity have led scientists to believe that another is likely to occur in the same vicinity. This program explores the evidence that remains from that 17th-century quake, including ghost forests, debris from tidal waves, and historic references including Native American legends and the...

The fascinating geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics. Colorful animations illustrate the movement of tectonic plates and the role this plays in the development of geologic features. Other terminology includes: theory of continental...

Around the world, up to 30 volcanoes erupt every day. Meet the people and wildlife that live alongside these volcanoes from Kilauea to Mount Etna, and discover how volcanoes cause destruction but also create and nurture life.

While it may not always seem possible, Earth is continually changing. This video provides insight into fascinating processes such as the formation of land, erosion, and volcanic eruptions. Other Earth processes are also investigated.

Footage of volcanic activity in Iceland and Hawaii, as well as earthquake events in California, illustrate how these dynamic forces affect our world. Through descriptions of actual volcanic and earthquake occurrences, students will discover how these dynamic forces affect our world. The video discusses the nature and causes of earthquakes and volcanoes. Other terminology includes: molten rock, magma, lava, cinder cone, shield volcano, composite volcano,...

If we could lift up the ground beneath our feet what would we see? We would see how the earth works. The earth is a machine its moving parts buried deep beyond our sight. But using the Earth Machine, a vast 3D model of our planet within an aircraft hangar. We can reveal the enormous geological processes driven by a vast heat engine buried 3000 miles beneath us. It has the power to move continents, create devastating earthquakes and powerful volcanoes....
