Fifty years ago, no one could explain mountains. Arguments about their origin were spirited, to say the least. Progressive scientists were ridiculed for their ideas. Most geologists thought the Earth was shrinking. Contracting like a hot ball of iron, shrinking and exposing ridges that became mountains. Others were quite sure the planet was expanding. Growth widened sea basins and raised mountains. There was yet another idea, the theory that the world's crust was broken into big plates that jostled around, drifting until they collided and jarred mountains into existence. That idea was invariably dismissed as pseudo-science. Or "utter damned rot" as one prominent scientist said. But the doubtful theory of plate tectonics prevailed. Mountains, earthquakes, ancient ice ages, even veins of gold and fields of oil are now seen as the offspring of moving tectonic plates. Just half a century ago, most geologists sternly rejected the idea of drifting continents. But a few intrepid champions of plate tectonics dared to differ. The Mountain Mystery tells their story.

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.
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.
A collection of essays and articles provides a study of how the planet works, discussing Earth's structure, geographical features, geologic history, and evolution.
Nearly three-quarters of EarthOCOs surface is covered by water, and more than 90 percent of the EarthOCOs living space is in the ocean. The oceans influence climate and weather patterns, affecting peopleOCOs daily lives in many ways. Marine science includes all of the sciences as they relate to the sea, including marine biography and oceanography. From the explorations of the Challenger to the theory of seafloor spreading to the invention of scuba gear, the 10 pioneers covered in this volume paved the way for marine scientists today. Each chapter contains relevant information on the scientist's childhood, research, discoveries, and lasting contributions to the field and concludes with a chronology and a list of print and Internet references specific to that individual."
