An intoduction of volcanoes and how they were formed.

Beakman uses a box sitting on a table designed to be the layers of the earth. He gets under the box and uses a red oven mit to push up through the box to show how magma pushes out of the earth's crust to create a volcano. He also uses a pie to demonstrate the same thing (heats too much and then the filling will come rupturing out of the crust).

Scientists attempt to collect samples of molten lava on Mount Nyiragongo to help study the earth's core.

Supervolcanoes can cause extreme destruction. 50,000 years ago in the Sierra Nevadas, a supervolcano erupted to create a 20 mile crater, known as the Long Valley Caldera.

The volcano erupts during a town hall meeting convened to discuss the threat of such an eruption. The residents panic and rush to leave.
