Earth Systems 3209

"The Earth System, Second Edition" employs a systems-based approach to examine Earth science at the global level. This text explores how: Earth's processes have connections to the past and to each other Seemingly small-scale changes to Earth can have large-scale effects Processes that are occurring now are molding the course of the future The second edition incorporates two new chapters: Modeling the Atmosphere-Ocean System--A discussion of why numerical models are necessary, how they are used, what they can tell us about past and future climates, and what their limitations are. A Focus on the Biota: Ecosystems and Biodiversity--Focuses on life's role in the Earth system, how ecosystems function, what biodiversity is, and whether or not biological diversity enhances the stability of ecosystems. Three categories of boxed text are included and offer a deeper study of the topics presented. A Closer Look--Includes more advanced concepts, results from current research, and explanations of interesting phenomena. Important Concepts--In-depth presentations of fundamental concepts from the natural sciences essential to our understanding of the Earth system. Thinking Quantitatively--Demonstrates how simple mathematics can be used to better understand the workings of the Earth system.

Comprehensive coverage of the whole Earth system throughout its entire existence and beyond Complete with a new introduction by the authors, this updated edition helps provide an understanding of the past, present, and future processes that occur on and in our Earth—the fascinating, yet potentially lethal, set of atmospheric, surface, and internal processes that interact to produce our living environment. It introduces students to our planet’s four key interdependent systems: the atmosphere, lithosphere, hydrosphere and biosphere, focusing on their key components, the interactions between them, and environmental change. The book also uses geological case studies throughout, in addition to the modern processes. Topics covered in the Second Edition of Earth Environments: Past, Present and Future include: an Earth systems model; components systems and processes; atmospheric systems; oceanography; surface and internal geological systems; biogeography; and aspects of Earth's record. The book also discusses the impact of climate and environmental change in a final chapter that draws together Earth's systems and their evolution, and looks ahead to potential future changes in Earth’s environments. Updated to include all the major developments since 2008 Features research boxes containing summaries based on recent key journal articles Includes a companion web site containing multiple choice revision quizzes for students, PowerPoint slides for lecturers, useful links, and more Presents further reading for each topic so that students can build their knowledge base to underpin their own undergraduate research project/dissertation Offers additional case studies in each chapter for enhanced reader understanding Earth Environments: Past, Present and Future is an excellent text for undergraduates in geosciences, environmental science, physical geography, natural hazards, and ecology.

Earth System: History and Natural Variability theme is a component of Encyclopedia of Natural Resources Policy and Management, in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Earth System: History and Natural Variability with contributions from distinguished experts in the field, presents a description of the cosmic environment around our planet influencing the Earth in a number of ways through variation of solar energy or meteorite impacts. The structure of the Earth and its rocks, waters and atmosphere is described. The Theme focuses on geological and evolutionary processes through the history of Earth's epochs and biomes since the Early Earth to the Quaternary. The unifying processes between the Earth's life and its rocks, waters and atmosphere are global natural cycles of carbon, sulfur and other elements that connect and influence the rate of geological processes, climate change, biological evolution and human economy. These five volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
