The Geology of the Earth: Of Forces, Rocks, and Time science DVD

This Great Pacific program outlines the forces that contribute to shaping the earth's surface, the movement of crustal plates, volcanic activity, physical and chemical weathering and erosion. The three major groups of rocks, igneous, sedimentary and metamorphic and their place in the rock cycle are also detailed. With dramatic volcanic and glacial footage and spectacular shots of the Oregon coast and the canyonlands of Arizona and Utah, this program is one of the most visually exciting that Great Pacific has ever produced.
