The next supercontinent : solving the puzzle of a future Pangea / Ross Mitchell.


"You have heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents. What about its previous iterations, Rodinia or Columbia? These "supercontinents" from Earth's past provide evidence that continents repeatedly join and divorce. Scientists debate exactly what that next supercontinent will look like (and what to name it), but they agree that one is coming. In this book, Ross Mitchell, a geophysicist who researches the supercontinent cycle, offers a tour of past supercontinents; introduces readers to the phenomena that will lead to the next one; and presents the case for a particular future supercontinent, called Amasia, that will form over the North Pole. Mitchell uses compelling stories of fieldwork and accessible descriptions of current science to introduce readers to the nuances of plate tectonic theory. He considers convection deep in Earth's mantle to explain the future formation Amasia (defined by the joining of North America and Asia) and to show how this developing theory can explain other planetary mysteries. He ends the book by asking if humans will live to see Amasia. He recognizes the chances of our species surviving the necessary 50 to 200 million years are vanishingly small, but the exercise gives readers a chance to imagine this landscape and to understand mimics for the geological processes required, for example in the form of geoengineering. An internationally recognized authority on the supercontinent cycle, Mitchell offers a compelling and updated introduction that offers readers a front-row seat to an ongoing scientific debate"-- Provided by publisher.
