The Tectonic Plates are Moving!
Plate tectonics is a revolutionary theory on a par with modern genetics. Yet, apart from the frequent use of clichés such as 'tectonic shift' by economists, journalists, and politicians, the science itself is rarely mentioned and poorly understood. This book explains modern plate tectonics in a non-technical manner, showing not only how it accounts for phenomena such as great earthquakes, tsunamis, and volcanic eruptions, but also how it controls conditions at the Earth's surface, including global geography and climate. The book presents the advances that have been made since the establishment of plate tectonics in the 1960s, highlighting, on the 50th anniversary of the theory, the contribu...
Supercontinent
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, an...
The Next Supercontinent
"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 ...

Language in Deep Human History
Understanding the evolution of language within the context of deep human history requires interdisciplinary work between linguists and scientists from a wide range of academic disciplines (e. g. archaeology, molecular biology, anthropology, genetics, biochemistry, etc.). The book aims to calibrate work on human evolution with current linguistic theory in an attempt to trace out a scientific story of how human language emerged and developed that has plausibility while remaining open to change through new linguistic and non-linguistic research.
Intra-oceanic Subduction Systems
Recycling of oceanic plate back into the Earth's interior at subduction zones is one of the key processes in Earth evolution. Volcanic arcs, which form above subduction zones, are the most visible manifestations of plate tectonics, the convection mechanism by which the Earth loses excess heat. They are probably also the main location where new continental crust is formed, the so-called 'subduction factory' About 400f modern subduction zones on Earth are intra-oceanic. These subduction systems are generally simpler than those at continental margins as they commonly have a shorter history of subduction and their magmas are not contaminated by ancient sialic crust. They are therefore the optimum locations for studies of mantle processes and magmatic addition to the crust in subduction zones.
