Michael Pidwirny, an associate professor at Okanagan University College, produced this website to educate users about "the spatial characteristics of the various natural phenomenon that exist in Earth's hydrosphere, biosphere, atmosphere, and lithosphere." This online textbook includes ten chapters filled with illustrations, images, and animations. The website provides links to the glossary for many of the key concepts discussed. At the end of each chapter, students can find summaries, study questions, and additional reading suggestions. Although the internet weblinks and geo-weblog are not yet available, students searching for resources dealing with the basics of physical systems will benefit from this site.
