How Electronic Microscopes Show Atoms
Atoms make up the very structure of all things and this 1:46 long video shows a microscope powerful enough to show how atoms are arranged on the surface. Diamond atoms are featured.
StudyJams - Weathering and Erosion
Weathering and erosion shape the world that is around us. Watch and listen as Zoe and RJ from the StudyJams Crew explain the science behind weathering and erosion.
Geology Plate Tectonics
This is a short explanation of Wegeners' theory of how all the continents were originally joined together and have drifted apart over time. (01:15)
Devils Tower
The video shows an intrusive volcanic tower. It explains how the volcano was formed. Introduction is a little silly. This video is a high school physics project. Grades 7-12. 2:29 min.
Mount Vesuvius
The volcano known as Mt. Vesuvius is a composite cone, or a strattle volcano, and one of the most famous on the planet. (01:00)
Volcanoes - Continental Drift and Plate Tectonics
This short video describes how volcanoes are created and what causes them to erupt. (1:37)
Undersea Volcanoes
From deep on the ocean floor at the mid-Atlantic ridge, huge undersea volcanoes rise up from the deep, with their own unique eco-systems and communities of undersea life on each of them. Â This video is a very unusual look at undersea volcanoes and life that they sustain. Run time 02:20
The Ring of Fire (Volcanoes), Part 4
The Pacific Ring of Fire (or sometimes just the Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. (08:02)
Volcanoes 101 Today we know volcanoes are openings or vents to the interior of the planet. About 1,500 volcanoes around the world are considered active, about 90% rest in the Ring of Fire, a band circling the Pacific Ocean.  While the Earth’s surface looks peaceful the crust is made up of slabs of rock that constantly shift, where the plates interact, volcanoes often form. Friction from shifting plates melts the Earth’s crust, causing ro
Kilauea Volcano Erupts - Dramatic Video
This video is suitable for older elementary, middle school, and high school students. Kilauea is the youngest and southeastern most volcano on the Big Island of Hawaii. Topographically Kilauea appears as only a bulge on the southeastern flank of Mauna Loa, and so for many years Kilauea was thought to be a mere satellite of its giant neighbor, not a separate volcano. However, research over the past few decades shows clearly that Kilauea has its own magma-plumbing system, extending to the surface
Violent Volcanoes
This video features outstanding images of volcanic activity. Images are a selection of favorite volcano photos submitted to MY SHOT by National Geographic readers. There is no narration; just background music. Video quality is excellent.
Seconds From Disaster: St. Helen's Eruption
Interviews and reenactments from survivors of a Mount St. Helen blast. Watch as they fight through the ash and cope with the aftermath from a volcano eruption. Some scenes may be upsetting for young children. Run time 02:47.
Volcano Eruptions : How Long Do Volcanoes Erupt?
The length of a volcanic eruption can vary dramatically, and some eruptions have been known to last continuously for decades. Learn about the lack of ability in predicting the length of volcanoes with help from the chair of a department of environmental studies in this video on volcano eruptions.

Dating Lava Flows on Mauna Loa Volcano, Hawaii
For hundreds of thousands of years, lava flows have created intricate patterns on the slopes of Hawaiʻi's Mauna Loa volcano. Until the mid-1970s, it was impossible to know when each of the flows occurred. However, as this video segment adapted from NOVA describes, scientists are now using tiny artifacts of life encased in hardened lava flows to piece together the mountain's complex geological and biological history. Closed captioning included. Run time 04:36.
How Did Life Emerge Here
The tip of a new volcanic island appears above the surface of the ocean. Solidified black lava gleams in the sunshine. Although it may not be obvious, the processes that will turn this new piece of land into a tropical paradise have already begun. This video segment adapted from NOVA chronicles an island's transformation from a barren lava flow to a rich ecosystem. Closed captioning included. Run time 05:13.
Volcano Eruptions
This is the best way to see the fury of a volcano -- through the lens of a camera. These scenes/images (30 seconds) should be prefaced with discussions about volcanoes.
Earthquake 101
This National Geographic video shows what happens to the earth's crust to cause an earthquake. When the trembling stops, the disaster is only the beginning. (02:38)
Earthquakes: Causes
This is a short, one-minute video that describes how and why earthquakes happen. The video shows photos of actual fault lines, as well as simple animation.
Earthquake Country; 2 Plate Tectonics
This video is suitable for middle school and high school students. Through live-action demonstrations and vivid animations, Dr. Pat Abbott explains how earthquakes have shaped the scenery and the character of the greater Los Angeles area. Dr. Abbott shows how faults capable of large earthquakes lie beneath most of the area, posing great risk to the millions of people living in earthquake country. Animations illustrate how and why earthquakes happen, how mountains and valleys have formed as a res
Earthquake Country, Introduction
There are other segments of this series on WatchKnow. This is the introductory series to 'Earthquake' country which is suitable for middle school and high school students. Through live-action demonstrations and vivid animations, Dr. Pat Abbott explains how earthquakes have shaped the scenery and the character of the greater Los Angeles area. Dr. Abbott shows how faults capable of large earthquakes lie beneath most of the area, posing great risk to the millions of people living in earthquake coun
