Genesis: Four Billion Years in the Making
Plot: The Great Valley in Africa - a crack of more than 6,500 kilometers in the earth's crust - is the result of the continental fracture that began about 20 million years ago. Volcanic eruptions, like the spectacular eruption of Hawaii's Kilauea volcano in Genesis, are the result of powerful tectonic processes that continually reshape the earth's surface
