1. What do you call the boundary between
the stratosphere and the troposphere?
1. The boundary between the stratosphere
and the troposphere is called the
tropopause.
2. The temperature of the stratosphere
increases as the distance from the Earth’s
surface increases?
3. The ozone layer is in our stratosphere.
2. The temperature of the stratosphere
increases or decreases as the distance from
the Earth’s surface increases?
3. Which layer of our atmosphere houses
the ozone layer?
4. What is the region where electrically
charged ions are formed as a result of the
absorption of solar energy?
5. About 4.4 billion years ago, what gases
were not believed to be present on Earth?
6. Oxygen was introduced into the
atmosphere as a byproduct of what?
7. How does the oxygen-carbon dioxide
cycle work?
8. A waste product of respiration in
animals that is used by plants to carry out
photosynthesis is?
9. How are greenhouse gases added to the
atmosphere?
10. In the last 100 years, how has excess
carbon been added to the atmosphere?
11. What forms does water exists on Earth?
12. With the input of solar energy, water
changes from a liquid to a gas during the
process of what?
13. As temperature increases, the possible
total humidity increases or decreases?
14. Warm, moist air will have ________
humidity and ___________ dew point.
15. The clouds that occur in the highest
altitude are usually what kind of clouds?
16. Sheet shaped clouds are called what
kind of clouds?
4. The region where electrically charged
ions are formed as a result of the
absorption of solar energy is the
ionosphere.
5. About 4.4 billion years ago, oxygen was
not believed to be present on Earth
6. Oxygen was introduced into the
atmosphere as a byproduct of
photosynthesis.
7. Animals produce carbon dioxide used by
plants for photosynthesis.
8. A waste product of respiration in
animals that is used by plants to carry out
photosynthesis is carbon dioxide.
9. One way greenhouse gases are added to
the atmosphere is through forest fires that
add CO2.
10. In the last 100 years, excess carbon has
been added to the atmosphere by power
plants, machinery and cars that burn fossil
fuels.
11. Water exists as a solid, liquid and gas
on Earth.
12. With the input of solar energy, water
changes from a liquid to a gas during the
process of evaporation.
13. As temperature increases, the possible
total humidity increases.
14. Warm, moist air will have high
humidity and high dew point.
15. The clouds that occur in the highest
altitude are usually cirrus clouds.
16. Sheet shaped clouds are called stratus
clouds?

across isobars toward or away from lowpressure centers?
28. Does weather change from day to day?
Yes or no.

atmosphere?
33.
17. Condensation and the formation of
cumulus clouds begin as the rising air
reaches its dew point.
18. Air becomes wind as it flows from high
pressure to high pressure.
19. The direction in which the wind moves
is influenced by the pressure gradient and
the Earth’s rotation.
20. Warm air rises because of its low
density?
21. The general geographic location of a
large low-pressure system is the tropics.
22. The leading edge of a cold air mass that
overtakes a region formally occupied by a
warm air mass is called a cold front.
23. High winds and strong thunderstorms
are characteristic of an approaching strong
cold front.
24. Tornadoes commonly occur in the
Midwest region of the United States?
25. The energy that powers a hurricane is
derived from condensation of water vapor.

cloud cover, and precipitation are indicated
on weather maps by symbols.
27. On a weather map, winds blow slightly
across isobars toward low-pressure centers?
28. Yes, weather change from day to day.

location is affected by latitude, season and
elevation.
30. The climate of a region is defined by
temperature and moisture.
