Offering a brief treatment of the elements of physical geography without sacrificing scientific content, Elemental Geosystems has been crafted to provide an accessible, systematic, and visually appealing start in physical geography. It is organized with a logical progression around the flow of energy, materials, and information to present topics in the same sequence in which they occur in nature. Engaging examples and applications of current events unfold as the author tells the story of modern Earth systems science. Climate change coverage incorporates the most current data available, and climate change science appears throughout where relevant impacts are important.

Robert W. Christopherson attended California State University—Chico for undergraduate work and received his Masters in Geography from Miami University, Oxford, Ohio. He joined the American River College faculty in 1970, where he founded the geography program.  From 1970 to 1999 he taught such courses as physical and cultural geography, weather and climate, humans and the environment, and humans in the urban environment, and is currently Professor Emeritus. 

Robert Christopherson is the recipient of numerous awards, including: the Patrons Chair and Student Association Teacher of the Year Awards at his college, the 1999 Distinguished Teaching Achievement Award from the National Council for Geographic Education, the 1998 Textbook Award for Geosystems, 3/E from the Text and Academic Authors Association, the California Geographical Society’s 1997 Outstanding Educator Award, and, most recently, the 2005 President's Award and 2005 Textbook Award for Elemental Geosystems, 4/E from the Text and Academic Authors Association.

Robert presented in seminar, television and radio, and research papers on topics such as the physical geography of the polar regions, global climate change, energy issues, and environmental awareness.  He and his professional photographer wife completed five polar expeditions; they attended the 2004 Arctic Climate Impact Symposium in Reykjavik, Iceland to gain photo and video coverage as well as research for Geosystems and Elemental Geosystems. Robert's wife has provided more than 300 exclusive photos for each of these texts.
