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.

An expert describes the carbon composition of diamonds, as well as the conditions necessary for diamond formation in this video segment from Nature.

In this video adapted from ANDRILL, find out how geoscientists get through more than a dozen football fields of ice and water in order to study the rock and sediment beneath Antarctica.

In this video profile produced for Teachers' Domain, meet teacher Dustin Madden, an IŰ__ŒóíŠupiaq who hopes to inspire students to take an active role in protecting the natural environment by giving them a foundation in math and science.

This video segment adapted from NASA's Goddard Space Flight Center discusses how a drought can have negative effects locally, for example by increasing the number of forest fires, and also globally, for example by impacting air quality thousands of miles away.

This video segment adapted from NOVA tells the tragic story of two Japanese seismologists who disagreed about the threat of earthquakes in the early twentieth century. Today, seismologists in California offer residents a probability of risk that an earthquake might occur.

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.

This video segment adapted from NOVA uses historical illustrations, photographs, and animations to explain how seismographs work, the difference between P and S waves, and the Richter scale.

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 media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.

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 features the area of the Congaree Swamp where the high ground and the flood plain meet. Learn how a few feet of difference in elevation on a floodplain can yield drastic changes in what youŰ__Ű__ŒŒÇll find living there.

In this adaptation of a video that high school students created in collaboration with the Environmental Justice League of Rhode Island, learn what's whack about our current food systems and the many actions individuals can take to address these issues.
