Volcanoes can erupt only once, but other volcanoes, such as Kilauea, can erupt continuously for almost 30 years. Discover how those who study volcanoes define active volcanoes with help from the chair of a department of environmental studies in this ...video on volcano eruptions.

Volcanoes form when magmas make their way to the Earth's surface and erupt. Volcanoes vary by type; cinder cones, stratovolcanoes or shield volcanoes. The intensity of the eruption depends in part on the composition if the lava, and following, how mu...ch gas is contained within the melt and how viscous (reseitive to flow) the magma is upon reaching the Earth's surface. This episode demonstrates how the release of gas is an importance factor in the violence of a volcanic eruption through the classic baking soda-vinegar volcano, and a more modern analog with diet soft drinks.
