Dynamic Earth Environments
The U.S./Russian collaboration that used the Space Shuttle and the Mir Space Station as platforms for acquiring remote sensing information about the Earth between 1996 and 1998 produced significant scientific results on hydrology, land use, and changes in some of the Earth's most dynamic environments. Many of these outstanding images are presented here and compared with photographs taken during earlier missions, allowing detection of changes on the Earth's surface. Studies reported in this fascinating volume include observations of El Niño-related phenomena; fluctuating water levels of the Caspian and Aral Seas; smoke, dust, and aerosols in the atmosphere; urban land use changes; and drought in the southeastern United States and Mexico. This valuable information, and the techniques used to gather it, will form the basis for future remote sensing studies to be conducted from the International Space Station.
Earth Environments
This book provides a comprehensive coverage of the major topics within undergraduate study programmes in geosciences, environmental science, physical geography, natural hazards and ecology. This text introduces students to the Earth's four key interdependent systems: the atmosphere, lithosphere, hydrosphere and biosphere, focussing on their key components, interactions between them and environmental change. Topics covered include: An earth systems model; components systems and processes: atmospheric systems; oceanography, endogenic geological systems and exogenic geological systems, biogeography and, aspects of the Earth's Record. The impact of climate and environmental change is discussed in a final chapter which draws together Earth's systems and their evolution and looks ahead to future earth changes and environments and various time periods in the geological record. Throughout the book geological case studies are used in addition to the modern processes.
Dynamic Earth
Dynamic Earth presents the principles of convection in the earth's mantle in an accessible style. Mantle convection is the process underlying plate tectonics, volcanic hotspots and, hence, most geological processes. The book summarises key observations and presents the relevant physics starting from basic principles. The main concepts and arguments are presented with minimal mathematics, although more mathematical versions of important aspects are included for those who desire them. The book also surveys geochemical constraints and mantle evolution. The audience for Geoff Davies' book will be the broad range of geologists who desire a better understanding of the earth's internal dynamics, as well as graduate students and researchers working on the many aspects of mantle dynamics and its implications for geological processes. It is also suitable as a text or supplementary text for upper undergraduate and postgraduate courses in geophysics, geochemistry, and tectonics.
