What is a thunderstorm?
a storm that generates snow
a storm that generates fog
a storm that generates thunder and lightening
a storm that generates ice and hail

What is a vortex?
a wall of air in front of a cold front
a rotating mass of air over the mid section of the country
a rotating column of air extending from the clouds to the ground
a wall of air in front of a warm front
During what season of the year are tornadoes most abundant?
Spring
Summer
Winter
Fall
What is the difference between a tornado watch and a tornado warning?
a watch is when a tornado has been spotted and a warning is when conditions may be suitable for a tornado to form
a watch is when conditions may be suitable for a tornado to form and a warning means the tornado has been spotted
a watch and a warning are both issued when a thunderstorm occurs, so no difference between the two
What scale is used to classify the strength of a tornado?
Enhanced Fujita
Fujita
Saffir-Simpson
Homer-Simpson
What scale is used to classify the strength of a hurricane?
Enhanced Fujita
Fujita
Saffir-Simpson
Homer-Simpson
What provides the energy source for a hurricane that affects the eastern United States?
cold salty water in the Atlantic
warm water in the Atlantic
cold fresh water in the Atlantic
warm water in the Pacific
At which latitudes are hurricanes likely to form?
between 30 and 40 degrees latitiude
between 40 and 50 degrees latitude
between 20 and 30 degrees latitude
between 5 and 20 degrees latitude
In a hurricane, where are the fastest winds and the most intense rainfall found?
On the outer bands to the south of the hurricane
On the outer bands to the north of the hurricane
along the eye wall of the hurricane
in the eye of the hurricane
In the eye of the hurricane, what type of weather do we see?
no precipitation, little to no wind, descending air
a great deal of precipitation, but no winds
strong winds, lots of precipitation, rising air
strong winds, lots of precipitation, descending air
Why do hurricanes lose their power as they move from the ocean to over land?
because the air cools and slows the hurricane
the hurricane loses it power source, warm water, and it encounters friction with the land surface
the hurricane usually will change direction as it moves over land and that causes it to slow down
upper level winds in the atmosphere will cause the hurricane to lose power.
