How The Earth Works

How the Earth Works explains with info-graphics, 3D illustrations and surprising cutaways, the function of thousands of organisms, natural systems and atmospheric systems, geographical and geological phenomena.

Nothing can be built without some excavation and transfer of soil (or rock) from one part of a site to another and this makes earthworks the most common product of civil engineering operations. Although normally seen as major structures, such as earth fill dams or large highways or railway embankments, the majority of earthworks are connected with minor civil works and building construction. Whatever the type of work, the principles are the same. Earthworks: a guide accumulates information on topics that are essential to earthworks engineering.

The book describes the structure, composition and evolution of the Earth, the main geological processes occurring on it, and how some crucial environmental matters that are amply debated in the media (e.g. pollution, greenhouse effect) can be fully understood by placing them in the holistic context of the system Earth as a whole. It provides basic information on a series of key geological issues, from the structure and composition of the Earth to the large-scale processes that characterize our planet, such as rock alteration and sedimentation, magmatism, geomagnetism, seismicity, plate tectonics, cyclical migration of chemical elements through various Earth reservoirs (Geochemical Cycles), and evolution of the planet from Hadean to present. It intends to reach a wide readership, which is interested in our planet and wish to have a general and comprehensive view of its origin, evolution and activity. Potential readership includes undergraduate and advanced undergraduate students in Geology and other scientific disciplines, and any moderately- to well-educated people interested in the surrounding world and eager to gain a basic knowledge of the Earth and to reach an integrated view of how our planet is working.

Focusing on questions about the earth such as What lies at the centre of the Earth?, Why do continents move? and Why do rivers bend? this book features simple, hands-on experiments and projects which use safe everyday equipment that let the reader discover for themselves the way the Earth works. It is also possible to create your own home laboratory with everyday materials from your home and garden.

Experiments and projects explore the earth's structure, features, and changing landscape.

Considered a wonder of the ancient world, the Newark Earthworks—the gigantic geometrical mounds of earth built nearly two thousand years ago in the Ohio valley--have been a focal point for archaeologists and surveyors, researchers and scholars for almost two centuries. In their prime one of the premier pilgrimage destinations in North America, these monuments are believed to have been ceremonial centers used by ancestors of Native Americans, called the "Hopewell culture," as social gathering places, religious shrines, pilgrimage sites, and astronomical observatories. Yet much of this territory has been destroyed by the city of Newark, and the site currently "hosts" a private golf course, making it largely inaccessible to the public. The first book-length volume devoted to the site, The Newark Earthworks reveals the magnitude and the geometric precision of what remains of the earthworks and the site’s undeniable importance to our history. Including contributions from archaeologists, historians, cultural geographers, and cartographers, as well as scholars in religious studies, legal studies, indigenous studies, and preservation studies, the book follows an interdisciplinary approach to shine light on the Newark Earthworks and argues compellingly for its designation as a World Heritage Site.

A necessary reexamination of Indigenous mounds, demonstrating their sustained vitality and vibrant futurity by centering Native voices Typically represented as unsolved mysteries or ruins of a tragic past, Indigenous mounds have long been marginalized and misunderstood. In Earthworks Rising, Chadwick Allen issues a compelling corrective, revealing a countertradition based in Indigenous worldviews. Alongside twentieth- and twenty-first-century Native writers, artists, and intellectuals, Allen rebuts colonial discourses and examines the multiple ways these remarkable structures continue to hold ancient knowledge and make new meaning—in the present and for the future. Earthworks Rising is organized to align with key functional categories for mounds (effigies, platforms, and burials) and with key concepts within mound-building cultures. From the Great Serpent Mound in Ohio to the mound metropolis Cahokia in Illinois to the generative Mother Mound in Mississippi, Allen takes readers deep into some of the most renowned earthworks. He draws on the insights of poets Allison Hedge Coke and Margaret Noodin, novelists LeAnne Howe and Phillip Carroll Morgan, and artists Monique Mojica and Alyssa Hinton, weaving in a personal history of earthwork encounters and productive conversation with fellow researchers. Spanning literature, art, performance, and built environments, Earthworks Rising engages Indigenous mounds as forms of “land-writing” and as conduits for connections across worlds and generations. Clear and compelling, it provokes greater understanding of the remarkable accomplishments of North America’s diverse mound-building cultures over thousands of years and brings attention to new earthworks rising in the twenty-first century.

A comprehensive history of the Earthworks movement provides an in-depth analysis of the forms that initiated Land Art, profiling top contributors and achievements within a context of the social and political climate of the 1960s, and noting the form's relationship to ecological movements.
