CHICAGO ROCKS! Geology in the City
ESCI 109, Section 03
Daily Objectives #15
(October 14, 2008)
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,
w Use a topographic map
to determine what direction a stream flows.
w Explain the difference
between surficial sediments and bedrock
NEW THIS TIME
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.
