26. • Greenhouse gases absorb heat, preventing
them from flowing out of the earth. Naturally,
greenhouse gases play an important role in
keeping the earth warm. The Earth would be
very cold if there were no greenhouse gases
that absorb heat.
• Global temperature increases when the amount
of greenhouse gases in the atmosphere
increases.

27. • Greenhouse gases include carbon dioxide,
methane (CH4), chlorofluorocarbons
(CFCs), nitrous oxide (N2O) and water
vapor.
• Greenhouse effect happens when there is
too much carbon dioxide in the
atmosphere.

28. As a student, what are the things that
you can do to lessen your carbon dioxide
emission?

29. Let’s Sum it up!
• 1. ____________is a gas that absorbs and
emits radiant energy within the
thermal infrared range.
• 2. ___________ serves as the glass walls
that trap the Sun's heat.

30. Let’s Sum it up!
• 3. The greenhouse gases are ____________,
______________, ____________, ____________
and ____________.
• 4. The Earth would be very ____ if there
were no greenhouse gases that absorb heat.
• 5. As carbon dioxide _________________,
global temperature also increases.

32. • 1. Why does the global temperature is
continuously increasing nowadays?
• a. Because of amount of heat from the sun
received varies.
• b. Because of amount of precipitation differs.
• c. Because the Higher altitudes, the lower
temperature.
• d. Because of the increasing amount of
Greenhouse gases.
•

33. • 2. Why do we need Greenhouse gases in the
atmosphere?
• a. because it keeps the earth warm
• b. because it makes the earth feel cold
• c. because it let the heat from the sun spread
out equally around the globe
• d. because its gaseous particles trap heat from
the surface

34. 3. What is the primary cause of the overall rising
trend in CO2 in the atmosphere?
a. CO2 is released by the oceans as they warm.
b. As human population grows, people exhale more
CO2.
c. The increase in CO2 is caused by burning of fossil
fuels.
d. CO2 is increasing because we are coming out of
an ice age.

35. 4. Which of the following is not a
greenhouses gas?
• a. Nitrous Oxide
• b. Carbon dioxide
• c. Methane
• d. Ozone

36. • 5. Based on the graph
above, what happened to
the amount of carbon
dioxide from 1880 to
2010?
• a. It is increasing
• b. It is decreasing
• c. It remains constant
• d. Neither increase nor
decrease

38. • 1. Why does the global temperature is
continuously increasing nowadays?
• a. Because of amount of heat from the sun
received varies.
• b. Because of amount of precipitation differs.
• c. Because the Higher altitudes, the lower
temperature.
• d. Because of the increasing amount of
Greenhouse gases.

39. • 2. Why do we need Greenhouse gases in the
atmosphere?
• a. because it keeps the earth warm
• b. because it makes the earth feel cold
• c. because it let the heat from the sun spread
out equally around the globe

Objective: Interpret the relationship of carbon dioxide and
temperature.

49. Guide Questions
• 1. How much is the increase in temperature
from 1880 to 2010?
• Answer: The increase in temperature from
1880 to 2010 is 1.3 F.

50. Guide Questions
• 2. What happened to the amount of carbon
dioxide from 1880 to 2010?
• Answer: The amount of carbon dioxide from
1880 to 2010 had increased by 100 ppmv

51. Guide Questions
• 3. What is the relationship between the amount
of carbon dioxide and global temperature?
• Answer: They are directly proportional. As the
amount of carbon dioxide increases, the global
temperature also increases.
