Dr. Michael J. Pidwerny, Department of Geology, Okanagan University College, British Columbia, Canada has developed a course entitled "Fundamentals of Physical Geography". His extensive, highly readable online textbook includes the following topics.

If you are interested in learning more about glaciation, a Hypertext Reference for Major Topics in Glaciology and Glacial Geology may be right for you. Developed by Dr. William W. Locke, Geology Department of Earth Sciences, Montana State University, Bozeman, MT; this site employs a menu that leads to discussions of a dozen major topics - each presented at both an introductory and advanced level. This arrangement allows easy movement between topics and facilitates exploring at the level that best meets your needs. To sample the type of information in the database, here is the Overview page.

Dr. R. Timothy Patterson, Department of Earth Sciences, Carleton University, Ottawa, Ontario, Canada offers a web-based course on Climate Change from a Geological Perspective.

This material, developed for an earlier course, is posted online and offers extensive coverage of the history of glaciation as part of a rich, systems-oriented look at the history of world climate change. Arranged in slide-show format, it will take an hour or more to view all of the slides; but you will find much information not covered in other references.
