Dirt

Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A...

What Is Erosion?

"Erosion has shaped the landscape all over the world. It occurs in small ways every day as wind and water move soil, rock, and other materials from place to place. Readers learn the specifics of how erosion happens and its place in the rock cycle. Full-color photographs showcase the amazing results of erosion from around the world, including waterfalls, canyons, and coastlines. Readers of all levels can use this volume to review or better understand a key area of Earth science through accessible language and simple definitions and explanations."

  • Publisher: Elsevier

Erosion and Environment focuses on the disturbance of the natural soil cover that exposes the soil surface to the action of erosion agents such as the destructive effects of water and wind. The topics discussed in this book include the effects of erosion on the national economy; classification of erosion; mechanism of erosion processes; theory of water erosion; and predicting intensity of water erosion and modeling erosion processes. The theory of wind erosion; intensity of wind erosion and predicting wind erosion; erosion and environmental control; and economics of erosion control are also elaborated in this text. This publication is beneficial to students and researchers conducting work on erosion and its processes.

Erosion

Timely and unsettling essays from an important and beloved writer and conservationist In Erosion, Terry Tempest Williams's fierce, spirited, and magnificent essays are a howl in the desert. She sizes up the continuing assaults on America's public lands and the erosion of our commitment to the open space of democracy. She asks: "How do we find the strength to not look away from all that is breaking our hearts?" We know the elements of erosion: wind, water, and time. They have shaped the spectacular physical landscape of our nation. Here, Williams bravely and brilliantly explores the many forms of erosion we face: of democracy, science, compassion, and trust. She examines the dire cultural and...
