exam, you should be able to do the
* Use the Public
Land Survey system (Township, Range, and Section) to give the location
of any point on a topographic map.
* Given a location's legal description in terms of the Public Land
Survey system, find that point on a topographic map.
* Define the terms divide, watershed,
and drainage basin (drainage area).
* Explain how a divide
can be located on a topographic map.
* Draw a
diagram illustrating the processes and products of the water cycle
* Explain what stream discharge is, how it is measured in the field,
and in what units of measurement it is expressed.
Describe the work that streams do (erosion, transportation, and
deposition) in terms of energy.
* On a map showing a stream meander,
indicate where erosion is likely
to be highest and where deposition is likely to take place.
* On a map, show an oxbow or oxbow lake and
explain how they formed (topo quad used in class: Arlington Heights).
* Explain what a stream floodplain is and how and
why it forms.
* On a topographic map, delineate the edges of a stream
* Measure the
width of the floodplain
of a river.
and explain factors that can affect the rate of water infiltration
into the subsurface.
* Describe some of the ways various watersheds might
from each other in terms of hydrologic characteristics (e.g. size of
drainage area, degree of urbanization,
and so on).
and use a test that allows you to determine how rapidly water
can infiltrate into different kinds of soil.
* Develop a method for using the stream table to model processes of
meandering streams and delta formation.
* Graph stream discharge data collected from the USGS web site.
stream discharge data in terms of how they relate to watershed
characteristics, as well as precipitation/weather events.
the terms aquifer
tell the the difference between them. Give examples of
geologic materials that make good aquifers and those that make good
* Explain what the term water table means, and tell
how its elevation is measured.
* Describe what a ground water well is, and tell how wells
* Calculate water elevation in wells based on depth-to-water data.
* Plot water table elevation in wells on a map, contour the
points, and tell what direction water is flowing based on the
mapped position of the water table.
points we plotted on the side of the ground water model last time, find
areas of faster and slower ground water flow.
* Use a ground water table elevation map to determine possible sources
of contamination found in a lake and a municipal well.
and describe the meaning of common weather measurements: temperature, barometric
pressure, relative humidity, wind speed and direction, and precipitation.
* Describe the temperature and moisture characteristics of these major
air masses: continental
polar, and maritime
what causes precipitation.
* Explain what conditions lead to frontal
* Describe a warm front and a cold front, draw each in profile (side)
view, and using the diagrams, explain how/why each leads to
* Explain what barometric pressure has to do with wind
* Describe the characteristics of high pressure systems and low
* Explain how high and low pressure systems affect Chicago's weather as
they move across the Midwest.
* Predict the weather in different cities based on the positions of
warm and cold fronts and high and low pressure systems.
