Supercontinent: Ten Billion Years in the Life of Our Planet

To understand continental drift and plate tectonics, the shifting and collisions that make and unmake continents, requires a long view. The Earth, after all, is 4.6 billion years old. This book extends our vision to take in the greatest geological cycle of all--one so vast that our species will probably be extinct long before the current one ends in about 250 million years. And yet this cycle, the grandest pattern in Nature, may well be the fundamental reason our species--or any complex life at all--exists. This book explores the Supercontinent Cycle from scientists' earliest inkling of the phenomenon to the geological discoveries of today--and from the most recent fusing of all of Earth's landmasses, Pangaea, on which dinosaurs evolved, to the next. Chronicling a 500-million-year cycle, Ted Nield introduces readers to some of the most exciting science of our time. He describes how, long before plate tectonics were understood, geologists first guessed at these vanishing landmasses and came to appreciate the significance of the fusing and fragmenting of supercontinents. He also uses the story of the supercontinents to consider how scientific ideas develop, and how they sometimes escape the confines of science. Nield takes the example of the recent Indian Ocean tsunami to explain how the whole endeavor of science is itself a supercontinent, whose usefulness in saving human lives, and life on Earth, depends crucially on a freedom to explore the unknown.

Review :
A book that examines the romance of its subject alongside its hard science... If you don't know much about how the planet's crust works, Nield's book will teach you the basics...He rocks.--Helen Brown"Daily Telegraph" (12/01/2007) An accessible account of how the Earth has several times consisted of a single island landmass and will again, in about 250 million years.--Peter Calamai"Toronto Star" (12/30/2007) As a geologist turned science journalist, editor and provocative blogger, Ted Nield has a complex view of life and science. His skills as a writer successfully convey in "Supercontinent" the recent exciting work in grand-scale geoscience to a wide scientific audience...The attempted reconstructions of past and future continents and oceans is a major field of activity in contemporary geoscience. To handle it without oversimplification or getting lost in a maze of detail is no small accomplishment.--David Oldroyd"Nature" (10/04/2007) Both informative and entertaining. [Nield] has thought well outside any academic box, touching on a huge diversity of topics...Nield relates many subjects that are currently major foci of research in Earth history to his theme.--Kevin Burke"Science" (11/30/2007) One of the best popularizations of geology...Giv[es] us a sense of the ancient yet powerful forces underneath us.--P. D. Smith"The Guardian" (10/06/2007) A fascinating and eye-opening book...In a most engaging way, Nield reveals how science has unraveled the complex evolution of our planet's surface, and presents the reader with a tantalizing glimpse of the Earth of the distant future. For centuries, people have dreamed of lost continents. Today, the author of this fascinating book shows, geologists can detect evidence of a continuing cycle of formation, breakup and reformation of one giant landmass--a supercontinent--over billions of years. Nield, editor of "Geoscientist" magazine, imagines what these supercontinents might have looked like and tells the stories of the scientists who have discovered and studied them...Making highly technical material understandable, Nield explains why "the Earth's Supercontinent Cycle matters to everyone, everywhere."
