ESCI 109, Section 03
Fall 2008

Daily Objectives #15 (October 14, 2008)                                                                                            Dr. Sanders

By the end of today's class, you should be able to do the following:


w Draw simple topographic maps that illustrate various landforms: hill, ridge, closed basin, valley

w Use a topographic map to determine what direction a stream flows.

Explain the difference between surficial sediments and bedrock


Use a physiographic map of the Chicago area to investigate landforms.

w Use a geologic map of the Chicago area to do the following:
           * list rocks and sediments that occur in the area;
find an area where bedrock is exposed
           * find the same area on each of several different maps, accounting for the differences in scale, and compare what each maps shows.

w List other geologic resources that can be found in the Chicago area, and tell how they can be used.

w List geologic resources not found in the Chicago area, and explain the considerations in making them available to Chicagoans.

w List some of the reasons why a quarry might be situated in a particular area, and why it might *not* be appropriate in some other areas.

w Show that you can use topographic and geologic maps to find good locations for quarries, considering all the factors we discussed.
