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.
