Children's LiteratureFour and a half billion years ago the infant Earth collided with a planet about the size of Mars. The impact pulverized both planets, unified their heavy iron cores into a single spinning mass, and spewed enough rock into orbit to form a ball about as wide as the United States. We call that ball the Moon. All that is just the beginning of the fascinating history of the Earth and Moon partnership. This well-written, well-researched little volume covers a lot in its 48 pages. It includes a geological history of our own planet that ranges from the structure of the atmosphere to the discovery of plate tectonics. It provides a history of the Apollo Mission. There is an ample glossary along with well-considered definitions of words and terms like "waxing gibbous" and "ozone." There is even a suggestion of how one might go about observing the moon with a good pair of binoculars and a notebook. In fact, there is easily enough in this book to serve as a high school text on the subject. The author is a former editor of Scientific American and Omni magazines. This book is part of the excellent "New Solar System" series. 2003, Smart Apple Media, Ages 10 to 14.
