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.
