ES322 Geomorphology Fall 2005 Final Study Guide NOTE The final exam is schedule for 12 00 PM on Tuesday Dec 6 2005 Study Tips read through book look at text figures compare to notes use study guide in combination with notes go back through the in class lab exercises make sure you can work the math units spend a couple days studying the exam will be essay and there is much material don t wait until the last minute carefully go through the notes some of the material we briefly discussed but did not spend much time on in class but the notes will give you the detail Exam Procedures 1 Final exam will be 120 points 2 Part 1 essay questions focusing mainly on material since mid term but with a limited number of comprehensive questions covering material prior to the mid term See key word recommendations below Note there will likely be an interpretive slide show as part of final identification of process materials landform age 3 Part 2 lab style quantitative questions map questions air photo questions identification of fluvial landforms coastal landforms tectonic landforms identification of basic climatic geomorphic features Association of landforms with processes Part 2 is OPEN BOOK you may use all resources make sure you have all of your equations down conversion tables will be available as necessary Bring a calculator Keywords To Focus On Since the Mid Term Fluvial
