The
Great Rift Valley in Africa, a 4,000-mile crack
in the earth's crust, is the result of continental
fracturing that began some 20 million years ago.
Volcanic eruptions, such as the spectacular eruption
of Hawaii's Kilauea Volcano featured in Genesis,
are the results of powerful tectonic processes that
are continually reshaping the earth's surface.
Directed by George Casey, featuring music by Paul
Novros and narrated by Malachi Throne. |
