There is a large and growing need for a textbook that can form the basis for integrated classes that look at minerals, rocks, and other Earth materials. Despite the need, no high-quality book is available for such a course. Earth Materials is a wide-ranging undergraduate textbook that covers all the most important kinds of (inorganic) Earth materials. Besides traditional chapters on minerals and rocks, this book features chapters on sediments and stratigraphy, weathering and soils, water and the hydrosphere, and mineral and energy deposits. Introductions to soil mechanics and rock mechanics are also included. This book steers away from the model of traditional encyclopedic science textbooks, but rather exposes students to the key and most exciting ideas and information, with an emphasis on thinking about Earth as a system. The book is written in such a manner as to support inquiry, discovery and other forms of active learning. All chapters start with a short topical story or vignette, and the plentiful photographs and other graphics are integrated completely with the text. Earth Materials will be interesting and useful for a wide range of learners, including geoscience students, students taking mineralogy and petrology courses, engineers, and anyone interested in learning more about the Earth as a system.
This book presents an overview of the chemistry, geology, toxicology and environmental impacts of arsenic, presenting information on relatively common arsenic minerals and their key properties. In addition, it includes discussions on the environmental impacts of the release of arsenic from mining and coal combustion. Although the environmental regulations of different nations vary and change over time, prominent International, North American, and European guidelines and regulations on arsenic will be reviewed. Includes information on recent environmental catastrophes (e.g. Bangladesh and China) A thorough discussion of the arsenic cycle, including the cosmological origin of arsenic Includes Appendices providing extensive glossary and measurement conversion tables
In the early twentieth century, many Americans were troubled by the way agriculture was becoming increasingly industrial and corporate. Mainline Protestant churches and cooperative organizations began to come together to promote agrarianism: the belief that the health of the nation depended on small rural communities and family farms. In Baptized with the Soil, Kevin M. Lowe offers for the first time a comprehensive history of the Protestant commitment to rural America. Christian agrarians believed that farming was the most moral way of life and a means for people to serve God by taking care of the earth that God created. When the Great Depression hit, Christian agrarians worked harder to keep small farmers on the land. They formed alliances with state universities, cooperative extension services, and each other's denominations. They experimented with ways of revitalizing rural church life--including new worship services like Rural Life Sunday, and new strategies for raising financial support like the Lord's Acre. Because they believed that the earth was holy, Christian agrarians also became leaders in promoting soil conservation. Decades before the environmental movement, they inspired an ethic of environmental stewardship in their congregations. They may not have been able to prevent the spread of industrial agribusiness, but their ideas have helped define significant and long-lasting currents in American culture.
