Water1992

520 An informative and entertaining, non-technical examination of the nature, properties, and importance of water. The text is divided into four principal parts--what is water?; water and life; water in motion; and water and humans, including the problem of pollution--and is thoroughly illustrated with photographs and specially commissioned artwork. Planet Earth is unique in the known solar system because of the presence of liquid water--a substance which covers almost three-quarters of the total surface area of the globe. In straightforward, non-technical language, this book examines this extraordinary substance--which we all take for granted.
