This textbook explains how mountains are formed and why there are old and young mountains. It provides a reconstruction of the Earths paleogeography and shows why the shapes of South America and Africa fit so well together. Furthermore, it explains why the Pacific is surrounded by a ring of volcanos and earthquake-prone areas while the edges of the Atlantic are relatively peaceful. This thoroughly revised textbook edition addresses all these questions and more through the presentation and explanation of the geodynamic processes upon which the theory of continental drift is based and which have led to the concept of plate tectonics. It is a source of information for students of geology, geophysics, geography, geosciences in general, general natural sciences, as well as professionals, and interested layman.

A source of profound influence and controversy, this landmark 1915 work explains various phenomena of historical geology, geomorphy, paleontology, paleoclimatology, and similar areas in terms of continental drift. 64 illustrations. 1966 edition.

In the early 1960s, the emergence of the theory of plate tectonics started a revolution in the earth sciences. Since then, scientists have verified and refined this theory, and now have a much better understanding of how our planet has been shaped by plate-tectonic processes. We now know that, directly or indirectly, plate tectonics influences nearly all geologic processes, past and present. Indeed, the notion that the entire Earth's surface is continually shifting has profoundly changed the way we view our world.

Views the continental drift hypothesis and its sequel in their scientific and historical context.

The theory of plate tectonics transformed earth science. The hypothesis that the earth’s outermost layers consist of mostly rigid plates that move over an inner surface helped describe the growth of new seafloor, confirm continental drift, and explain why earthquakes and volcanoes occur in some places and not others. Lynn R. Sykes played a key role in the birth of plate tectonics, conducting revelatory research on earthquakes. In this book, he gives an invaluable insider’s perspective on the theory’s development and its implications. Sykes combines lucid explanation of how plate tectonics revolutionized geology with unparalleled personal reflections. He entered the field when it was on the cusp of radical discoveries. Studying the distribution and mechanisms of earthquakes, Sykes pioneered the identification of seismic gaps—regions that have not ruptured in great earthquakes for a long time—and methods to estimate the possibility of quake recurrence. He recounts the various phases of his career, including his antinuclear activism, and the stories of colleagues around the world who took part in changing the paradigm. Sykes delves into the controversies over earthquake prediction and their importance, especially in the wake of the giant 2011 Japanese earthquake and the accompanying Fukushima disaster. He highlights geology’s lessons for nuclear safety, explaining why historic earthquake patterns are crucial to understanding the risks to power plants. Plate Tectonics and Great Earthquakes is the story of a scientist witnessing a revolution and playing an essential role in making it.

This series offers a detailed, informative and lively discussion on four of the key areas of physical geography. Each book helps develop the knowledge of how specific features of the Earth are formed, their causes and effects, patterns and processes, and our study and understanding of them. The series aims not only to answer, but also to inspire questions about different environments and landscapes, and our relationships with some of the greatest forces of nature we experience on Earth. Photographs bring the effects of the subject vividly to life, while diagrams enhance the readers' practical understanding of the processes that have created the landscapes of the world in which we live today.

This book describes the expansion of the land-based paleomagnetic case for drifting continents and recounts the golden age of marine geoscience.

Why did American geologists reject the notion of continental drift, first posed in 1915? And why did British scientists view the theory as a pleasing confirmation? This text, based on archival resources, provides answers to these questions.
