An internationally recognized scientist shows that Earth’s separate continents, once together in Pangea, are again on a collision course. You’ve heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These “supercontinents” from Earth’s past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming. In this engaging work, geophysicist Ross Mitchell invites readers to remote (and sometimes treacherous) lands for evidence of past supercontinents, delves into the phenomena that will birth the next, and presents the case for the future supercontinent of Amasia, defined by the merging of North America and Asia. Introducing readers to plate tectonic theory through fieldwork adventures and accessible scientific descriptions, Mitchell considers flows deep in the Earth’s mantle to explain Amasia’s future formation and shows how this developing theory can illuminate other planetary mysteries. He then poses the inevitable question: how can humanity survive the intervening 200 million years necessary to see Amasia? An expert on the supercontinent cycle, Mitchell offers readers a front-row seat to a slow-motion mystery and an ongoing scientific debate.

Explores the Supercontinent Cycle from the earliest recorded time to the geological discoveries of today including the drifting of the continents and the evolution of dinosaurs.

Did you know that millions of years ago the Earth only had one super continent? If you look at a globe today, you’d notice how continents fit into each other like puzzle pieces. But how did the super continent break apart and become seven different continents? Let’s look at the mechanics of the continental drift in this book for fifth graders. Grab a copy today.

There are hundreds of books and thousands of scientific articles about the Galápagos. This volume is distinctive. The authors, Guillermo Paz-y-Miño-C and Avelina Espinosa, synthesize, integrate, and conceptualize the most recent evolutionary-biology research being conducted in the archipelago’s terrestrial and aquatic environments; the conflicts resulting from human interactions with nature, including local population growth and tourism practices in the context of short- and long-term conservation efforts; and make predictions about the destiny of the Galápagos’ unique biodiversity and landscapes under various scenarios of climate-change impacts, urbanization trends, diversification of tourism, and conservation investments. Offering over 260 figures and diagrams, this work will appeal to a broad audience, including professors in academia, college instructors, postdoctoral fellows, graduate students, and research undergraduates. Another target audience is study-abroad and international field-trip instructors and their students who travel to the Galápagos year-round. Science writers and policymakers will find in this book useful information to discuss and debate about imminent environmental threats to afflict the Galápagos as a consequence of human population growth, tourism practices, and climate change.

Encyclopedia of Geology, Second Edition presents in six volumes state-of-the-art reviews on the various aspects of geologic research, all of which have moved on considerably since the writing of the first edition. New areas of discussion include extinctions, origins of life, plate tectonics and its influence on faunal provinces, new types of mineral and hydrocarbon deposits, new methods of dating rocks, and geological processes. Users will find this to be a fundamental resource for teachers and students of geology, as well as researchers and non-geology professionals seeking up-to-date reviews of geologic research. Provides a comprehensive and accessible one-stop shop for information on the subject of geology, explaining methodologies and technical jargon used in the field Highlights connections between geology and other physical and biological sciences, tackling research problems that span multiple fields Fills a critical gap of information in a field that has seen significant progress in past years Presents an ideal reference for a wide range of scientists in earth and environmental areas of study

Surveys the origin of continents, and the accretion and breakup of supercontinents through earth history. This book also shows how these processes affected the composition of seawater, climate, and the evolution of life.
