                   g.   When air becomes __________________ it contracts (becomes more dense).

                   h.   The cold air __________________________ to the surface near the north and south

                          ________________________ .

                   i.     The ______________________ air from the poles returns along the surface to the
                          _____________________ (a) where it is heated again.



















                   2.     Refer to the illustrations above and use the following terms to fill in the blanks


                            below. Some of the terms may be used more than once.

                            Clockwise               parallel flow                isobar


                            counterclockwise.             parallel flow             inward

                            high                    flow                 outward





                            a.  Figure 5A represents a ____________________pressure area.


                            b.  We know 5A represents a _______________________pressure area because

                                  the arrows showing wind flow indicate a _____________________movement.


                            c.  When the wind flow is shown you do not need to have atmospheric lines in order

                                 to pressure readings on the _______________________ lines in order to identify


                                 a "high" or a "low."
