Rock Sculptures

Programme Outline

The stunning background of Arizona's Painted Desert is used to explore the variety of rock types. The startling colours are explained in terms of their mineral content and the elements that colour them. The formation of different types of rock such as sedimentary and metamorphic rocks is beautifully illustrated. Computer graphics are used to demonstrate the forces of erosion and the ultimate destruction of the famous Three Sisters. The programme provides a useful summary of this wide ranging topic.
