8.  Wind is caused by differences in
a. Precipitation
b. Humidity
c. Air pressure
d. Turbulence

9.  How are local winds different from global
winds?
 Local winds are caused by unequal heating
in a small area

10.  Why do land breezes form?
 Because land cools off faster than water

11.  What type of wind blows from a specific
direction over long distances?

Global wind

12.  Earth’s rotation makes winds seem to curve.
What is this called?
 Coriolis effect

13.  When do clouds form?
 When water vapor condenses

14.  What type of clouds produce
thunderstorms?
 Cumulonimbus

15.  What are high feathery clouds called?
 Cirrus

16.  What type of clouds are layered and cover
most of the sky?
 Stratus

17.  Any form of water that falls from a cloud is
called what?
 Precipitation

18.  How does energy travel through space to
the Earth?
 As electromagnetic waves/radiation

19.  Energy from the sun that reaches the Earth
is visible light, infrared radiation and
_______________.
 Ultraviolet radiation

20.  What tool is used to measure how hot or
cold the air is?
 Thermometer

21.  A sea breeze is a type of what kind of wind?

Local wind

22.  What tool is used to measure air pressure?
 Barometer

 21%

26.  What is altitude?
 The measurement of how high something is
above sea level

27.  What human activity causes the most air
pollution?
 Vehicle exhaust

28.  What is rain or sleet mixed with acids
called?
 Acid rain

29.  Why does air have pressure?
 Because it has mass

30.  How do we measure air pressure?
 With a barometer

31.  What does the ozone layer do?

Protects us from ultraviolet radiation

32.  Photochemical smog forms in the presence
of what?
 Sunlight

33.  What happens to happens to air pressure as
altitude increases?
 It decreases

34.  In what layer of the atmosphere is the ozone
layer or ozonosphere found?
 Stratosphere

35.  What are the four main layers of the
atmosphere in order from the ground
upwards?
 Troposphere, stratosphere, mesosphere,
thermosphere

36.  What does the mesosphere do?
 Causes meteors to burn up before striking
Earth

37.  Where does the aurora borealis form?
 In the ionosphere
