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

TOPOGRAPHIC MAPS

w   Review:  Sketch a profile illustrating a floodplain, and explain how a floodplain would appear on a topographic map.  (The quadrangles we used were Clinton Illinois-Iowa, Menominee Illinois-Iowa, Blackhawk Illinois, Atkinson Illinois, and Geneseo Illinois.)

w   Review:  Delineate a watershed boundary (divide) on the Galena Illinois quadrangle.

w   Review:  Using the stream table, demonstrate how erosion, transport, and deposition of sediments occur, and how a stream channel, floodplain, and delta form.


WEATHER

w   Explain what humidity is and tell how humidity measurements are expressed.

w   Explain what an air mass is.

w   Explain how moisture content and temperature of an air mass affect its density.

w   Describe continental polar (cP), maritime tropical (mT), continental Arctic, (cA), and other air masses that affect the continental United States.  (See http://okfirst.mesonet.org/train/meteorology/AirMasses.html and http://www.qc.ec.gc.ca/meteo/Documentation/Masse_e.html .)

w   Explain what a front is.

w   Using the worksheet attached here, study and interpret the weather maps we have been collecting for the past month.  Today, the focus is on air mass temperature, fronts, and precipitation.
