This video adapted from the Valdez Museum & Historical Archive, explores what happened during the Great Alaska Earthquake of 1964 through original footage, first-person accounts, and animations illustrating plate tectonics.

In this video adapted from Alaska Sea Grant, discover why multiple tsunamis resulted from the Great Alaska Earthquake of 1964.

This video segment adapted from NOVA explains why ice sheets move. To find out how fast they move, scientists carve a tunnel through a glacier.

What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.

The impact of natural disasters is made vivid in this video segment adapted from NOVA. A small town in Iceland, prepared for recurrent avalanches, is devastated when one takes a new and damaging path.

This interactive resource adapted from the National Park Service presents the key concepts of cave and karst systems, including how and where they form, different types, and various cave environments.

In this video adapted from the Arctic Athabaskan Council, learn how warmer temperatures in the Arctic are transforming the landscape, triggering a host of effects such as permafrost thawing and insect infestations.

This interactive resource adapted from the National Park Service describes the different kinds of sediments that make up coastlines, with a focus on the variety in color, size, and sorting.

This interactive resource adapted from the National Park Service describes the many forces that affect shorelines, including tides, weathering, erosion, and deposition.

In this video segment, ZOOM guest Cassie takes us on a tour of the coral reef near her home in Key Largo, Florida, and points out some of its unique features.

In this video segment from Nature, learn the geological process by which the next Hawaiian island will be formed.

In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaii to regenerate after a volcanic eruption.

In this video segment adapted from NOVA, animations are used to show how the hills around Los Angeles were formed by earthquakes at small thrust faults that extend outward from the larger San Andreas fault.

The history of earthquakes in the San Francisco Bay area is plotted on a digital map and analyzed in this video segment adapted from NOVA.

In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.

In this video produced by ThinkTV, explore the effects of land masses on local climate conditions, and learn about regional impacts of land-atmosphere interactions.

In this video from Common Ground and Cleaner Water, Tribby Vice, a Kentucky farmer, talks about the changes he has made on his farm to protect the water quality of the stream running through his property and the watershed in which he lives.

In this video segment adapted from NOVA scienceNOW, scientists in western Greenland explain how a glacier there is shrinking and moving faster due to increased melting.

In this video segment adapted from NOVA, scientists investigate how farming along the Mississippi River impacts floods and what can be done about it.

This video segment from NatureScene examines the landforms of Death Valley and how they came to be.
