CHICAGO ROCKS!  Geology in the City
ESCI 109, Section 03
Fall 2008


Review for Exam #3 (December 9, 2008)                                                                                            Dr. Sanders


TWO VERY IMPORTANT REMINDERS ABOUT THE EXAM:

  w BRING YOUR ISGS BOOK WITH YOU!
 
w THE EXAM IS AT ->
TEN <- A.M.!!

For the exam, you should be able to do the following:

Figure out what topographic maps you will need to study your team's area.

w Develop your team communication skills.  .

w Put together the "Moraine Mosaic" puzzle pieces.

w Be ready to complete the Team Contract homework for next week (see the Homework page). 

w Explain what the Moraine Mosaic shows about Chicago geology (and physiography).

w Put together information from the physiographic map, the mosaic pieces, your Chicago road map, and the geologic map to discern what the geology of the surrounding area is.

w Solve the problem of "The Blue Island Worm".

w Tell what causes a glacier to move and deposit sediments, and why sediments "pile up" in a moraine at the end of the glacier.

w Explain the relationship between moraines and glaciers.  Sketch a map showing the direction of movement of glaciers into the Chicago area during the Ice Age, and showing the trend of the moraines that resulted.

w
Explain what is meant by the term intermorainal.

w
Solve the problem of "The Blue Island Worm".

w Describe the sediments present on the Chicago Lake Plain, and contrast them to the sediments in the Chicago area moraines.

w Describe what is expected in your team poster presentation.

w Describe the sediments present on the Chicago Lake Plain, and contrast them to the sediments in the Chicago area moraines.

w Describe what is expected in your Individual Geologic Research assignment. 

w Log into www.delicious.com , create, tag, and annotate an entry, which you will do in the Individual Geologic Research assignment. 

w Explain what is meant by stream gradient

w Measure a stream gradient using topographic maps. 

w Compiling data from the entire class, explain the patterns among stream gradients found in this part of Illinois.

w Explain the story of the reversal of the Chicago River.  On a map, point out the length that was reversed and explain the reasoning and the method used.

w Compiling data from the entire class, explain the patterns among stream gradients found in this part of Illinois.

w Explain the term intermorainal and point out intermorainal areas on the p. 5 ISGS map and the Willman map. 

w Describe the relationship between northeastern Illinois' rivers and major streams and the intermorainal area.

w Describe the subcontinental divide that stretches through Chicago,sketch a diagram illustrating the meaning of the term, and tell what you would have to do to go see it. 

w
Identify the "Zion beach-ridge plain", show where it occurs on a map of the Chicago area, tell what surficial sediments occur there, and explain why it is perched so high above Lake Michigan .

w
Tell the story of Chicago's geology. 

w
Provide meaningful feedback regarding the presentations, field trips, and other course activities.
