SIDELIGHTS: A geologist with a particular expertise in how mountains are formed, Marcia Bjornerud is the author of Reading the Rocks: The Autobiography of the Earth, a geological history "that will instill an appreciation for the dynamism and comparative uniqueness of our planet," according to Booklist reviewer Gilbert Taylor. Bjornerud describes the major theories and recent developments in this complex field, as well as intriguing asides, such as the theory that the oceans were once entirely frozen and the fact that a small zircon found in Australia is the oldest object native to planet Earth. "Bjornerud chronicles the watersheds in Earth's history from the primordial supernova that seeded the nascent solar nebula to the man-made cataclysms of global warming," explained a Publishers Weekly reviewer, who added that at present humanity produces sixteen times as much carbon dioxide as volcanoes produce. At the same time, she sets forth the remarkable powers of renewal and recycling that the Earth has displayed over its long history, allowing it to regulate itself through redistribution of elements among the oceans, the interior, and the atmosphere. A Kirkus Reviews contributor particularly praised "Bjornerud's plain-English approach," which makes her work easily accessible to the average reader.
