Once, the power of volcanoes was thought to be the work of the gods. Now scientists better understand the subterranean forces that cause these steaming mountains to spew fire and molten rock. Follow the pace and rhythm of geologic movement and time, and see how scientists track this motion to predict the next time a volcano will blow.

The video discusses the nature and causes of earthquakes and volcanoes. Other terminology used includes: molten rock, magma, lava, cinder cone, shield volcano, composite volcano and caldera.

A volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface. Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent.

Volcanoes are awesome manifestations of the fiery power contained deep within the Earth. These formations are essentially vents on the Earth's surface where molten rock, debris, and gases from the planet's interior are emitted.
