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.
w Explain what humidity is and tell how humidity measurements are expressed.
w Explain what an air mass is.
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 .)
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.
