This Tenth Edition maintains its solid coverage of the two major energy systems of Earth: the plate tectonic system and the hydrologic cycle. Boasting a new four-part organization, this renowned book contains current content and a striking illustration package, while exposing readers to a global view of Earth and helping them look at the world as geologists do. Part I introduces geologic systems, the materials modified by these systems, and geologic time. Part II examines the hydrologic system and its subsystems chapter by chapter. Part III explores the details of the tectonic system and includes chapters on divergent, transform, and convergent boundaries, as well as mantle plumes—the subsystems of the tectonic system. Part IV looks at our planet in two ways: by first examining the geologic resources that make life possible, and then by comparing and contrasting Earth with other planets to reveal how unique our planet is. For professionals with a career or interest in geology, Earth science, and/or environmental science.
In 1848 news of the discovery of gold in California triggered an enormous wave of emigration toward the Pacific. Lured by the promise of riches, thousands of settlers left behind the forests, rain, and fertile soil of the eastern United States in favor of the rough-hewn lands of the American West. The dramatic terrain they struggled to cross is so familiar to us now that it is hard to imagine how frightening—even godforsaken—its sheer rock faces and barren deserts seemed to our forebears. Hard Road West brings their perspective vividly to life, weaving together the epic overland journey of the covered wagon trains and the compelling story of the landscape they encountered. Taking readers along the 2,000-mile California Trail, Keith Meldahl uses the diaries and letters of the settlers themselves—as well as the countless hours he has spent following the trail—to reveal how the geology and geography of the West directly affected our nation’s westward expansion. He guides us through a corrugated landscape of sawtooth mountains, following the meager streams that served as lifelines through an arid land, all the way to California itself, where colliding tectonic plates created breathtaking scenery and planted the gold that lured travelers west in the first place. “Alternates seamlessly between vivid accounts of the 19th-century journey and lucid explanations of the geological events that shaped the landscape traveled. . . . The reader comes away with both an appreciation for the arduous cross-continental wagon journey and an understanding of the events that created such a vast and difficult landscape.”—Library Journal “[Meldahl] draws on his professional knowledge to explain the geology of the West, showing how centuries of geological activity had a direct effect on the routes taken by the travelers. . . . Meldahl provides a novel account of the largest overland migration since the Crusades.”—Science News
The purpose of this book is to expose undergraduate students to the use of applied mathematics and physical argument as a basis for developing an understanding of the response characteristics, from a systems viewpoint, of a broad class of dynamic physical processes. This book was developed for use in the course ECE 355, Dynamic Systems and Modeling, in the Department of Electrical and Computer Engineering at the University of Michigan, Ann Arbor. The course ECE 355 has been elected primarily by junior and senior level students in computer engineering or in electrical engineering. Occasionally a student from outside these two programs elected the course. Thus the book is written with this class of students in mind. It is assumed that the reader has previous background in mathematics through calculus, differential equations, and Laplace transforms, in elementary physics, and in elemen tary mechanics and circuits. Although these prerequisites indicate the orientation of the material, the book should be accessible and of interest to students with a much wider spectrum of experience in applied mathemati cal topics. The subject matter of the book can be considered to form an introduc tion to the theory of mathematical systems presented from a modern, as opposed to a classical, point of view. A number of physical processes are examined where the underlying systems concepts can be clearly seen and grasped. The organization of the book around case study examples has evolved as a consequence of student suggestions.
This text demonstrates the roles of statistical methods, coordinate transformations, and mathematical analysis in mapping complex, unpredictable dynamical systems. Written by a well-known authority in the field, it employs practical examples and analogies, rather than theorems and proofs, to characterize the benefits and limitations of modeling tools. 1991 edition.
This book provides a comprehensive coverage of the major topicswithin undergraduate study programmes in geosciences, environmentalscience, physical geography, natural hazards and ecology. This text introduces students to the Earth's four keyinterdependent systems: the atmosphere, lithosphere, hydrosphereand biosphere, focussing on their key components, interactionsbetween them and environmental change. Topics covered include: An earth systems model; componentssystems and processes: atmospheric systems; oceanography, endogenicgeological systems and exogenic geological systems, biogeographyand, aspects of the Earth's Record. The impact of climate and environmental change is discussed in afinal chapter which draws together Earth's systems and theirevolution and looks ahead to future earth changes and environmentsand various time periods in the geological record. Throughout the book geological case studies are used in additionto the modern processes.
A history of the origin and development of the earth's surface. Answers real questions about rock hunting and collecting, physical properties and atomic structures of minerals, types of igneous rocks, meteorites, sedimentary rocks, limestone, metamorphic rocks, ores, determining the ages of rocks, and much more. 48 halftones. 40 line illustrations. 15 color illustrations on covers.
