Volcanoes March 21, 2006   Past Episodes

A volcano can be described as part of the earth’s plumbing system. Magma, or molten rock from under the earth pushes upward through a sort of natural pipe and sometimes explodes lava out of the ground. Volcanoes created many of Idaho’s mountains and plains. Scientists study volcanoes to learn more about the earth and to protect the millions of people who live near these fascinating geological features.
