1.
Why are there global winds?
a)
because the cold air sinkes from the poles to the equator
b)
because the earth is rotating from east to west
c)
because the sun heats the air at the equator more than anywhere else on earth
2.
Which way to the global winds blow in each hemisphere?
a)
east to west in Northern Hemisphere and west to east in the Southern Hemisphere
b)
west to east in Northern Hemisphere and east to west in Southern Hemisphere
c)
North to south in the Northern Hemisphere and south to north in Southern Hemisphere
d)
south to north in the Northern Hemisphere and north to south in the Southern Hemisphere
3.
What is the Coriolis Effect and how does it effect global winds?
a)
Curving of winds due to rotation of earth curves wind counterclockwise in Northern Hemisphere and clockwise in the Southern Hemisphere
b)
Movement of ocean currents caused by earth rotation' counterclockwise in Northern Hemisphere and clockwise in Southern Hemisphere
c)
curve of global winds caused by global rotation clockwise in Northern Hemisphere and counterclockwise in Southern Hemisphere
4.
How does the Coriolis Effect influence hurricanes and cyclones
a)
determines how powerful they will be
b)
determines where they will go
c)
determines where they form
d)
determines the direction of the wind rotation
5.
Where do hurricanes form?
a)
In the pacific off South America
b)
In the Atlantic off South America
c)
In the Atlantic off Africa
d)
In the Gulf of Mexico
6.
The two most important things to hurricanes are
a)
high pressure and cool water
b)
low pressure and cool water
c)
low pressure and warm water
d)
high pressure and warm water
7.
In the Northern Hemisphere, hurricane winds blow
a)
harder than in the Southern Hemisphere
b)
counterclockwise
c)
clockwise
d)
less than in the Southern Hemisphere
8.
Why do hurricanes lose so much of their power when they hit land?
a)
they run into high pressure which kills hurricanes
b)
land is cooler than water therefore the hurricane loses the energy it needs from warm temperatures
c)
the land breezes shear the hurricane therefore making it harder for it to stay together
d)
the hurricane no longer receives heat and moisture from the warm ocean it uses for fuel
9.
Why do hurricanes benefit from strong upper level winds?
a)
The upper level winds are warm and moist and provide most fuel for the storm
b)
the upper level winds help to move the rising air away from the hurricane helping the winds to move haster
c)
the upper level winds help to drive the hurricane winds down faster to increase circulation of the winds
d)
the upper level winds offset wind shear so it does not weaken the storm
