CHICAGO ROCKS! Geology in the City
ESCI 109, Section 03
Fall 2008
| Review from before | New this week |
| � steep slope � gentle slope � plain � hill � closed basin |
� ridge � valley � stream valley |
w Interpret the contours on
a topographic map showing the landforms listed above.
w Using a US Geological
Survey (USGS) topographic map, do the following:
� Determine the latitude and longitude of the sides of the quadrangle;
� Determine the elevation of a given point on the map;
� Identify streams;
� Find the elevation of a stream at a given point on the map.
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.
w Use a physiographic
map of the Chicago area to investigate landforms.
w Explain the difference
between surficial sediments and bedrock
w Explain what
dolomite (also called dolostone) is, tell why it
might be a commonly-used geologic resource in the Chicago area, and give
examples of how it can be used.
w Draw simple
topographic maps that illustrate various landforms: hill, ridge, closed basin,
valley
w Use a topographic map

w Explain the difference between surficial
sediments and bedrock
w 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.
w Use a
physiographic map of the Chicago area to investigate landforms.
w Using maps of
different scales and purposes, "zoom in" and "zoom out" to correlate the maps
and compile information for a particular area.
w Determine what topographic quadrangles are adjacent
to any given quad.
w Use the topographic
map index found on the Willman map.
w Use the
Cook
County topographic map index on the ISGS website.
w Use a topographic map
to create topographic profiles of a landform on the south side that we'll refer
to as "the worm".
w Use critical thinking to create and evaluate
hypotheses for the origin of "the worm".
w Revisit "the
worm": show how you can pinpoint it accurately on the Blue Island quadrangle,
and re-draw the N-S and E-W profiles across it.
w Describe the "grid
drawing" method of creating a picture (see
an example here) and explain how we are using it in this class.
w Use the topographic map index found on the Willman
map.
w Planning Your Future: Based on the information
provided by Dr. David Helfand of the Career Counseling Office, identify the
factors that determine what job or career path may be right for you. List
both "Career Awareness" factors and "Self Awareness" factors.
w Using the materials
provided in class, understand everything you need to complete Homework #5.
w Continue creating
"puzzle pieces" for the Moraine Mosaic.
w
Demonstrate how to use a hand level and stadia rod
to measure the slope of the land surface.
w Be ready to
participate in our field trip to Gompers Park on Thursday. The
park is on the southwest corner of Foster and Pulaski. Meet in the east parking
lot (off Pulaski) at class time, Thursday, October 30!
w Draw a diagram illustrating the slope-measuring
method you used.
w Using the field trip handout, explore and describe
the water features in the park.
w List the members of your Team Project team, and
describe the Team Project objectives and requirements.
w Using the
Team Project overview document, be ready to complete the first team project
assignment (see the Homework page) by the required deadline.
