Earth Environments: Past, Present and Future
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.

- ‘New research boxes’ contain summaries based on recent key journal articles
- A companion web site with resources for students and lecturers is available, containing multiple choice revision quizzes for students, PowerPoint slides for lecturers, useful links, and more
- Presents graded further reading for each topic so that Level 2 & 3 students can build their knowledge base to underpin their own undergraduate research project/dissertation
- Includes a series of fact sheets for each chapter in the component systems and processes section each with a concentration of summary tables and illustrations designed to convey as much specific information as possible
"This comprehensive introductory work covers basic information on geology, oceanography, and meteorology/climatology. Huddart and Stott (both, Liverpool John Moores Univ., UK) take a systems approach, and thus focus on the interactions between the major components of the Earth system. The book is divided into six main sections: "Introduction to Earth Systems," "Atmosphere and Ocean Systems," "Endogenic Geological Systems," "Exogenic Geological Systems," "Principles of Ecology and Biogeography," and "Global Environmental Change." Each of the 3 1 chapters is well illustrated with black-and-white and color graphs and a variety of photographic images. Chapters conclude with references for further reading and suggested exercises that can be used to test student comprehension of the material. This clear, concisely written book is more inclusive and extensive than many disciplinary introductory works, and could form the basis for a course lasting at least two semesters. Extensive 17-page subject geographic index." (CHOICE, December 2010)
"The strength of this book is that it is an up-to-date summary of the major themes in geosciences, as the blurb on the back cover states. As such, it is an ideal book for students to dip in and out of throughout their undergraduate career alongside other key texts. . . there are also good reading lists at the end of each chapter". (The Geographical Journal, 4 December 2010)
