1. Why do most hurricanes in the Northern Hemisphere move from east to
Because they are
attracted to the cooler, drier coast ofNorth America. Because
the hurricane’s natural rotation pushes it westward. Because
the tropical trade winds blow from east to west. Because
that’s the way the earth rotates.
Fill in the blank: Doubling the maximum wind speed of a hurricane will _________
the damage the hurricane does.

What are the top conditions needed for a hurricane to form?
cluster of tropical thunderstorms combines with warm, moist ocean air. Extremely
warm and extremely cold fronts collide over the ocean. An
oceanic tornado creates a circling mass of clouds. A
butterfly flaps its wings in Asia.
does a hurricane’s intensity decrease rapidly over land?
of friction between the storm and the ground. Because
bits of dust and dirt picked up by the storm slow its rotational inertia. Because
the opposing jet stream pushes the hurricane in the opposite direction. Because
the land is rougher, cooler and not as moist as the ocean.
Which of the following is NOT a major difference between a hurricane and a
have no fronts. Hurricanes
weaken rapidly over land. The
centers of hurricanes are warmer than their surroundings. A
land-based cyclone's winds can't reach hurricane-force speeds.
Which of the following is NOT used to measure a hurricane’s wind speed?
from weather satellites. Wind-measuring
analysis of wave height and storm distance. Special
wind monitors dropped by planes.
What is the expected maximum sustained wind speed for a class five
hurricane—considered the most destructive?
least 115 mph At
least 128 mph At
least 155 mph At
least 172 mph
8. In what part of a hurricane are the strongest winds found (in the
“right” side of the hurricane (the northern side for a west-moving storm). The
“left” side of the hurricane (the southern side for a west-moving storm). The
edge of the eye.
At what sustained wind speed does a tropical storm become a hurricane?
10. Which of the following is NOT a positive environmental effect of a
floods add nutrients to marshes. Hurricane
winds aid birds in
their migration. Intense
rain causes soil run-off to estuaries threatened by rising sea levels. Land
eroded from beaches can form new habitats.
