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.
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
In today's world, it is more acceptable to be depressed than to be lonely-yet loneliness appears to be the inevitable byproduct of our frenetic contemporary lifestyle. According to the 2004 General Social Survey, one out of four Americans talked to no one about something of importance to them during the last six months. Another remarkable fact emerged from the 2000 U.S. Census: more people are living alone today than at any point in the country's history—fully 25 percent of households consist of one person only. In this crucial look at one of America's few remaining taboo subjects—loneliness—Drs. Jacqueline Olds and Richard S. Schwartz set out to understand the cultural imperatives, psychological dynamics, and physical mechanisms underlying social isolation. In The Lonely American, cutting-edge research on the physiological and cognitive effects of social exclusion and emerging work in the neurobiology of attachment uncover startling, sobering ripple effects of loneliness in areas as varied as physical health, children's emotional problems, substance abuse, and even global warming. Surprising new studies tell a grim truth about social isolation: being disconnected diminishes happiness, health, and longevity; increases aggression; and correlates with increasing rates of violent crime. Loneliness doesn't apply simply to single people, either—today's busy parents "cocoon" themselves by devoting most of their non-work hours to children, leaving little time for friends, and other forms of social contact, and unhealthily relying on the marriage to fulfill all social needs. As a core population of socially isolated individuals and families continues to balloon in size, it is more important than ever to understand the effects of a culture that idealizes busyness and self-reliance. It's time to bring loneliness—a very real and little-discussed social epidemic with frightening consequences-out into the open, and find a way to navigate the tension between freedom and connection in our lives.
Every couple wants a happy relationship and a meaningful career but how do we balance both? In Couples that Work, Professor Jennifer Petriglieri shifts away from the language of sacrifice and trade-offs and focuses on how couples can successfully tackle the challenges they will face throughout their lives--together. The book explores key questions like: - Can you and your partner have equally important careers or must you prioritise one over the other? - How can you juggle children or family commitments without sacrificing your work? - Does every decision require compromise or can you find solutions that benefit you both? Identifying common triggers and traps, and presenting engaging exercises to help you avoid and overcome them, this book will help every couple design their own unique way to combine love and work at every stage of their journey. 'Hugely insightful. All couples must read this now' Susan David, author of Emotional Agility 'Managing one career is hard enough; two often seems impossible. In this book, Jennifer shares what she's learned about how couples can not only survive but thrive' Adam Grant, author of Originals

The second edition of this widely cited textbook continues to provide a concise but comprehensive introduction to cave and subterranean biology, describing this fascinating habitat and its biodiversity. It covers a range of biological processes including ecosystem function, evolution and adaptation, community ecology, biogeography, and conservation. The authors draw on a global range of examples and case studies from both caves and non-cave subterranean habitats. One of the barriers to the study of subterranean biology has been the extraordinarily large number of specialized terms used by researchers; the authors explain these terms clearly and minimize the number that they use. This new edition retains the same 10 chapter structure of the original, but the content has been thoroughly revised and updated throughout to reflect the huge increase in publications concerning subterranean biology over the last decade.
Presents an introduction to volcanoes and earthquakes, explaining how the movement of the Earth's interior plates cause their formation and describing the volcanoes which currently exist around the world as well as some of the famous earthquakes of the nineteenth through twenty-first cenuturies.
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.
