The answer is d . The cold front extends from western Michigan to central Texas. You can tell the loca-
tion of the cold front because of a sharp temperature difference between the east and west sides of
the frontal boundary.
V I S U A L C O N C E P T C H E C K 8 . 2
The answer is b . The cold front caused mT air to uplift rapidly. Remember that a cold front plows ag-
gressively into relatively warm, moist air. This interaction causes the mT air to lift rapidly.

One would expect Hurricane Floyd to move to the west because the prevailing winds are easterly at
low latitudes. At some point, the hurricane would begin to interact with the midlatitude westerlies,
causing the hurricane to veer northeastward. In fact, Hurricane Floyd migrated in just this manner,
moving westward toward Florida. Shortly before it reached Florida, however, Floyd veered to the
northeast and just grazed the mainland of the United States.
