Lava Descent
From NationalGeographicVideo, produced by National Geographic

Located at Erta Ale Volcano in Ethiopia. The moonscape is twelve times the size of Manhattan in New York. Photographer, Karsten Peter wants a sample of molten rock from the lava lake. Located at three continental plates, base of this volcano is 30...0 feet below sea level. This is one of the world’s oldest living lava lakes, and has been bubbling for at least the last 90 years. They climb down in to the crater. He gets down near the lava, but needs to put on a thermal suit. He tosses cable into the lava and it melts the cable. He settles for recently hardened samples from the edge. Hopefully these rocks will give scientists information on where they have been. Video is very interesting video and is of very good quality. Good for elementary grade and middle school students.

Volcanoes 101
From NationalGeographicVideo, produced by National Geographic
|

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 peace...ful 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 rock beneath the crust to liquefy. This magma then becomes a volcano by erupting through rifts in the plates. Not all lava is the same. Volcanoes can be deadly, but it can also be good, it created 80% of Earth’s surface and the air we breathe, rich soil for farming, and some countries harness the heat to create geothermal energy. Video is very interesting and good quality. Good for elementary grade and middle school students.

Explore the science and beauty of these natural features. Video gives history that the Earth was once an icy ball others believe Earth was cold, but not quite ice. 700 million years ago the Earth was much colder. Volcanoes warmed the surface of th...e Earth, video shows a volcano that erupted in 2004 where a volcano was filmed erupting through an ice sheet in Central Iceland, this is what would have happened millions of years ago but on a global level. What saved the planet were the tons of carbon dioxide gas. As volcanoes erupted more and more carbon dioxide was released. The layer of carbon dioxide built up and trapped enough heat to end the endless winter. A thaw began and Earth would never be the same. Video is very interesting and is very good quality. Good for elementary grade and middle school students.

The eruption of Mount Pinatubo in 1991 was the largest volcanic eruption in 80 years. The explosive eruption deposited tons of ash on the towns and villages near the volcano's base. Even more devastating than the eruption, however, were the devastati...ng flows of water and debris that resulted when monsoon rains mixed with the accumulated volcanic ash. This video segment adapted from NOVA depicts some of the impact of these events on the communities surrounding the volcano. Closed captioning. Run time 03:30.
