Chapter 11: Hurricanes
1) What determines when a tropical depression or storm is given hurricane status?
A) central pressure B) water temperature
C) wind speed D) diameter
4) As a strong hurricane moves ashore, which of the following causes the most
devastating damage in the coastal zone?
A) storm surge B) torrential rains
C) strong winds D) all are equally significant
8) What type of clouds is most common in a hurricane?
A) nimbostratus B) stratus
C) cirrus D) cumulonimbus
10) What general circulation wind belt is the place of origin for hurricanes?
A) horse latitudes B) westerlies C) trade winds D) doldrums
12) Why do hurricanes in the Atlantic move toward the west during their early stages?
A) steering influence of ocean currents
B) warmer water temperatures guide them
C) they move away from areas of high salinity
D) Coriolis effect guides them
E) prevailing winds are from the east
13) The initial detection and monitoring of tropical storms that may become hurricanes is
accomplished by
A) ocean ships
B) coastal observers
C) ocean buoys
D) aircraft
E) satellites
16) Why do hurricanes initially form only in the tropics?
A) stronger pressure gradients are found there
B) subsiding air currents are found there
C) Coriolis is weaker there
D) warm water temperatures are found there
18) Which one of the following is more intense?

25) Since detection and tracking of hurricanes is now quite accurate, why does damage
from these storms continue to increase?
A) continued development of coastal areas
B) poor forecasts of landfall area
C) hurricane intensity is greater
D) changes in tidal patterns
26) Which of the following can diminish the intensity of a hurricane?
