• Obj: Review for your Weather and Oceans
Test
• Please take a seat
• Have out your test review and begin
working on it
• I will give you 20 minutes to complete your
review at your table then we will go over it
• 5th period: You are not talking to ANYONE.
You will do this paper silently.
Weather and Oceans Test
1. Lines of equal air pressure on a weather map
are called
Isobars
2. Lines of equal temperature are called
Isotherms
3. Draw what hot air molecules look like:
least dense
Draw what cold air molecules look like:
Most dense
Label the circle that is most dense and the circle that is
least dense.
4. Why is air pressure highest closest to sea
level on Earth?
More air molecules due to gravity
5. High pressure systems are associated with
Happy, clear weather.
6. Low pressure systems are associated with
Lousy, cloudy weather.
7. What heats up the atmosphere fueling
the water cycle?
The Sun
8. Why does oil float on water?
It is less dense
9. Air Molecules Comparison:
Top of Mountain to Bottom of Mountain
What makes the air molecules different from the top
and the bottom of the mountain?
gravity
10. Draw a convection current, include the
sun, and labels describing what type of air
rises and what type of air sinks.
Why is this current important?
Convection currents create weather and winds on Earth, they distribute
heat from the tropics to other parts of the Earth
11. What fuels hurricanes?
Warm air and water in tropical oceans
12. Why do hurricanes form in the area around the
equator?
Air and water is warmed by the Sun. Those areas of
the world are receiving more direct sunlight.
13. Why are hurricanes important to Earth?
They move heat from the tropics, though destructive,
without them, the tropics would be too hot for
anyone to live there.
14. What is humidity?
The moisture that is available in the atmosphere
15. Draw the symbols for warm, cold, stationary and
occluded front:
16. What direction does weather travel across the
U.S.?
West to East
17. What kind of weather does a cold front bring?:
thunderstorms form along a cold front, followed by clear
cold weather
18. What kind of weather does a warm front bring?:
several days of rain can be expected
19. Describe an occluded front:
When a warm air mass is trapped between two cold air
masses; cold rain can be expected
20. Describe a stationary front:
When a cold and warm air mass meet, but neither is
strong enough to move the other out of the way.
Several days of fog and rain can be expected.
21. What is an air mass?
A body of air with certain similar characteristics
like temperature and humidity.
22. An air mass that forms over water will be
wet .
23. An air mass that forms over land will be
dry.
24. An air mass that forms over the equator will be
warm.
25. An air mass that forms over the polar regions
will be
cold.
26. Air masses have the same conditions as
The area where they are formed.
27. The movement of air masses causes changes
in
weather.
Maritime
Polar
Continental

Which air mass brings cold and dry air?
Continental Polar
Which air mass brings wet and warm air?
Maritime Tropical
29. Cold water currents have a cooling effect on
the continental coastlines they touch.
30. Warm water currents have a warming effect
on the continental coastlines they touch.
31. Cities with mountains blocking the ocean air
tend to be dry and cold.
32. Cities by the coast tend to get a lot of rain.
33. Cities in the center of the continent tend to be
cold and dry.
34. Where does most marine life live?
By the coast, water is shallow, tends to be warm
and has lots of nutrients
35. What are the types of fronts on the map?
Cold, warm and occluded
36. What type of pressure is over the state of New
York? High
37. Where do you predict the cold front will be October
14, (tomorrow)? Further east and south
38.
39. How does moving air affect global temperatures?
Warm air and cold air is distributed in convection currents as
warm air rises and cool air sinks. High pressure areas move
to low pressure areas, making global temperature more
evened out.
40. Is this high pressure or low pressure?
High, because the pressure increases as you go
to the center
