Note this is the old website for GEO 102 (Winter 2003).  New website is on Blackboard.  All information here is available there.

Special Notices:  Watch this space for announcements!

Reading assignments through the end of the quarter are posted online.

Lecture Info


Book: The textbook for this class is Elemental Geosystems (3rd edition) by Christopherson. The book itself has a website containing information that you may find useful in this class, including review questions.

Cost-saving ideas: I have placed a copy of the 3rd edition of the hardcopy book on reserve at the Valley Library. While I can't guarantee the book will always be available (depending on how many students use it), the option exists if you need to save the cost of the book.  You also may use an older edition of the book (the 2nd edition would be OK), or the larger, more in-depth book entitled "Geosystems".  In both cases the page, chapter, and figure numbers given in class and in the syllabus will be different.

The Valley Library Reserve Desk has copies of the textbook.

Syllabus, etc.: The handout that will be given on the first day of class is available here on-line.

Reading Assignments: Reading assignments prior to the midterm are summarized here (subject to change).

Midterm (1999): An example midterm is available on-line. Note that this midterm (from 1999) is not formatted properly in the on-line version. Also available are the answers to the example midterm.

Midterm (2002): This midterm is also available, along with the answers.

Extra Information and Web Links

Links to plate tectonics animations. The animations shown in class, created by Prof. Tanya Atwater at UCSB,  are available here. Note that you will need Quicktime and that the files are large.

Oregon Climate Service, headed by our 1/24/03 guest lecturer and state climatologist George Taylor, a.k.a. "The Weather Guy".  OCS is the state repository for weather and climate information, much of which is accessible from their web site.

Links to ozone losses. Good information about the Antarctic "ozone hole" can be found at, including a number of animations. The website contains a number of other animations and data sets.

The Myth of the Flat Earth. Educated people of all persuasions have known that the Earth is a sphere for more than two millenia, not just since Columbus' voyage, as is sometimes suggested. Here is an essay by UCSB history professor J. B. Russell on the issue. While his conclusions regarding the motives of scientists and historians are controversial, it provides a good illustration of how prejudices affect academics the same as other people. Also see, e.g., Russell, J. B., Inventing the flat earth, History Today, 41(8), p. 13-19, 1991 (follow the link from any OSU computer to get to the article online).

Weather: Cloud Types. Also more cloud pictures.

Review sheet for clouds video.

Stream levels (hydrographs) for the state of Oregon:  USGS website.
