What is a rock? What is a mineral? How do they form? The answers may not seem like electrifying entertainment, but in the hands of the award-winning Eyewitness science series, the subject seems as bright and vibrant as the Hope diamond. Accompanied by breathtaking photography, award-winning actor Martin Sheen provides some "rock-solid" narration as he recounts the remarkable evolutionary journey of inorganic materials.

The Eyewitness Rock and Mineral DVD shatters the stone's reputation for "rock-solid" permanence. Discover how rocks keep a constantly changing record of our planet's fascinating history, and see how minerals are at the very core of our civilization. DVD runs 35 minutes. Also includes a special "Making of Eyewitness" feature that runs 25 minutes.
