Here are the sands of Hawaii and Tahiti, the Sahara and the Poles, a volcano, each exquisitely different, and each telling a fascinating geological story. Red sand and yellow, white sand and black, singing sand and quicksand: Greenbergs pictures reveal the subtle differences in their colors, textures, sizes, and shapes. And as this infinitesimal world unfolds so does an intriguing explanation of how each grain of sand begins and forms and finds itself in a particular place, one of a billion and one of a kind.2008 | PDF | ISBN: 0760331987 | 113 pages | 101 Mb
