The Next Supercontinent by Ross Mitchell Pdf

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.

The Next Supercontinent by Ross Mitchell Pdf

"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"--

Supercontinent by Ted Nield Pdf

The shifting continents of the Earth are heading for inevitable collision: 250 million years from now, all the land masses on this planet will come together in a single, gigantic supercontinent which no human is ever likely to see. That future supercontinent will not be the first to form on Earth, nor will it be the last. Each cycle lasts half a billion years, making it the grandest of all the patterns in nature. It is scarcely a century since science first understood how Pangaea, the supercontinent which gave birth to dinosaurs, split apart, but scientists can now look back three-quarters of a billion years into the Earth's almost indecipherable past to reconstruct Pangaea's predecessor, and computer-model the shape of the Earth's far-distant future. Ted Nield's book tells the astounding story of how that science emerged (often in the face of fierce opposition), and how scientists today are using the most modern techniques to draw information out of the oldest rocks on Earth. It also reveals the remarkable human story of the Altantis-seeking visionaries and madmen who have been imagining lost or undiscovered continents for centuries. Ultimately all supercontinents exist only in the human imagination, but understanding the 'Supercontinent Cycle' represents nothing less than finally knowing how our planet works.

Everything Under the Heavens by Howard W. French Pdf

From the former New York Times Asia correspondent and author of China's Second Continent, an incisive investigation of China's ideological development as it becomes an ever more aggressive player in regional and global diplomacy. For many years after its reform and opening in 1978, China maintained an attitude of false modesty about its ambitions. That role, reports Howard French, has been set aside. China has asserted its place among the global heavyweights, revealing its plans for pan-Asian dominance by building its navy, increasing territorial claims to areas like the South China Sea, and diplomatically bullying smaller players. Underlying this attitude is a strain of thinking that casts China's present-day actions in decidedly historical terms, as the path to restoring the dynastic glory of the past. If we understand how that historical identity relates to current actions, in ways ideological, philosophical, and even legal, we can learn to forecast just what kind of global power China stands to become--and to interact wisely with a future peer. Steeped in deeply researched history as well as on-the-ground reporting, this is French at his revelatory best.

A Synthesis of the Galápagos by Guillermo Paz-y-Miño-C,Avelina Espinosa Pdf

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.

Continents and Supercontinents by John J. W. Rogers,M. Santosh Pdf

To this day, there is a great amount of controversy about where, when and how the so-called supercontinents--Pangea, Godwana, Rodinia, and Columbia--were made and broken. Continents and Supercontinents frames that controversy by giving all the necessary background on how continental crust is formed, modified, and destroyed, and what forces move plates. It also discusses how these processes affect the composition of seawater, climate, and the evolution of life. Rogers and Santosh begin with a survey of plate tectonics, and go on to describe the composition, production, and destruction of continental and oceanic crust, and show that cratons or assemblies of cratons became the first true continents, approximately one billion years after the earliest continental crust evolved. The middle part of the book concentrates on supercontinents, beginning with a discussion of types of orogenic belts, distinguishing those that formed by closure of an ocean basin within the belt and those that formed by intracontinental deformation caused by stresses generated elsewhere. This information permits discrimination between models of supercontinent formation by accretion of numerous small terranes and by reorganization of large old continental blocks. This background leads to a description of the assembly and fragmentation of supercontinents throughout earth history. The record is most difficult to interpret for the oldest supercontinent, Columbia, and also controversial for Rodinia, the next youngest supercontinent. The configurations and pattern of breakup of Gondwana and Pangea are well known, but some aspects of their assembly are unclear. The book also briefly describes the histories of continents after the breakup of Pangea, and discusses how changes in the composition of seawater, climate, and life may have been affected by the sizes and locations of continents and supercontinents.

Ancient Supercontinents and the Paleogeography of Earth by Lauri J. J Pesonen,Johanna Salminen,Sten-Ake Elming,David A.D. A.D. Evans,Toni Veikkolainen Pdf

Ancient Supercontinents and the Paleogeography of Earth offers a systematic examination of Precambrian cratons and supercontinents. Through detailed maps of drift histories and paleogeography of each continent, this book examines topics related to Earth’s tectonic evolution prior to Pangea, including plate kinematics, orogenic development, and paleoenvironments. Additionally, this book discusses the methodologies used, principally paleomagnetism and tectonostratigraphy, and addresses geophysical topics of mantle dynamics and geodynamo evolution over billions of years. Structured clearly with consistent coverage for Precambrian cratons, this book combines state-of-the-art paleomagnetic and geochronologic data to reconstruct the paleogeography of the Earth in the context of major climatic events such as global glaciations. It is an ideal, up-to-date reference for geoscientists and geographers looking for answers to questions surrounding the tectonic evolution of Earth. Provides robust paleogeographies of Precambrian cratons based on high-quality paleomagnetic and geochronologic data and critically tested by global geological datasets Includes links to updated databases for the Precambrian such as PALEOMAGIA and the Global Paleomagnetic Database (GPMDB) Presents full-color maps of the drift histories of each continent as well as their paleogeographies Discusses key questions regarding continental drift, the supercontinent cycle, and the geomagnetic dipole hypothesis and analyzes palaeography in the context of Earth’s holistic evolution

Supercontinent Cycles Through Earth History by Z.X. Li,D.A.D. Evans,J.B. Murphy Pdf

The supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of continental lithosphere that resists subduction during the closure of old ocean basins, and the consequent reorganization of mantle convection cells leading to the opening of new ocean basins. Characteristic timescales of the cycle are typically 500 to 700 million years. Proposed spatial patterns of cyclicity range from hemispheric (introversion) to antipodal (extroversion), to precisely between those end members (orthoversion). Advances in our understanding can arise from theoretical or numerical modelling, primary data acquisition relevant to continental reconstructions, and spatiotemporal correlations between plate kinematics, geodynamic events and palaeoenvironmental history. The palaeogeographic record of supercontinental tectonics on Earth is still under development. The contributions in this Special Publication provide snapshots in time of these investigations and indicate that Earth’s palaeogeographic record incorporates elements of all three end-member spatial patterns.
