This surrounds the Earth and is where weather
occurs.
3
What is atmosphere?
4
This is the pressure of the atmosphere.
5
What air pressure?
6
This is the amount of water in the air.
7
What is humidity?
8
Humidity is highest at a parking lot,
neighborhood, or forest.
9
What is forest?
10
Name the three types of clouds.
11
What are cirrus, cumulus, and stratus?
12
These global winds blow from west to east in
North America.
13
What are prevailing winds?
14
These winds depend on local changes in
temperature.
15
What are local winds?
16
A large body of air which has nearly the same
temperature and humidity throughout.
17
What is an air mass?
18
The boundary between air masses.
19
What is a front?
20
During the day, the wind blows towards the _____
during the night, the wind blows towards the
_____.
21
What is land, sea?
22
When heat changes liquid water to water vapor.
23
What is evaporation?
24
Name two forms of precipitation.
25
What is rain and snow? (other answers may be
accepted)
26
When water vapor clings to dust particles in the
air and form clouds.
27
What is condensation?
28
When humidity is high enough, this happens.
29
What is precipitation?
30
Most weather occurs at this time.
31
What is, when two different air masses meet at
their boundaries, or fronts?
32
The average of all weather conditions through all
seasons over a period of time.
33
What is climate?
34
The climate of a very small area.
35
What is a microclimate?
36
When Earths climate changes for just a year or
so.
37
What is the El Nino effect?
38
When carbon dioxide in the atmosphere absorbs
some of the heat given off by Earth.
39
What is the greenhouse effect?
40
Vice-president Al Gore won the Nobel Peace Prize
for his efforts in educating people on this. It
is an abnormally rapid rise in Earths average
temperature.
41
What is global warming?
42
This is warmer than the other (city or
countryside).
43
What is the city is warmer than the
countryside? Bonus Why?
44
Burning this also warms up the air.
45
What are fuels?
46
In a city, these block winds that might blow away
warm air.
47
What are large buildings?
48
Changes in this, might be caused by a change in
the size or shape of Earths orbit or a change in
the tilt of Earths axis.
49
What is Earths temperature?
50
If Earths average temperature rises just a few
more degrees, these might melt and flood many
coastal cities.
51
What are icecaps/ glaciers?
52
The symbol for this type of front is a straight
line with triangles on it (some call them
icicles).
53
What is a cold front?
54
The symbol for this type of front is a straight
line with half circles on it (some call them
suns).
55
What are warm fronts?
56
You can predict what the weather will be like in
a day or two by looking in this direction on the
weather map.
57
What is looking to the west? Bonus Why?
58
Other than the information on a weather map, you
can also predict the weather if you have this
information.
59
What is cloud cover, types of clouds, and/or
wind speed and direction?
60
A rising barometer generally means this type of
weather, whereas a falling barometer means this
type of weather.
61
What is fair weather, stormy weather?
