● Ultraviolet Radiation
● X-Rays
● Gamma Rays
2. Which part of the EM spectrum has the longest
wavelength?
● Radio Waves
3. Which part of the EM spectrum has the shortest
wavelength?
● Gamma Rays
4. Match the following purposes with their part on the
EM spectrum
● Colors of the rainbow ​→​ Visible Light
● Causes sunburns ​→​ Ultraviolet Radiation
● Makes objects feel warmer ​→​ Infrared
● Used for communication ​→​ Radio Waves
● Used to treat some cancers ​→​ Gamma Rays
● Used to determine if you broke a bone ​→
X-Rays
● Used in radar detectors ​→​ Microwaves
● Used to broadcast television signals ​→
Radio
● Used in remotes ​→​ Infrared Radiation
● Used in security devices in airports ​→
X-Rays
5. What are CFC’s
● Chlorofluorocarbons
6. What products are CFC’s found in?
● Aerosols, Refrigeration systems, Air
conditioners
7. Why are CFC’s bad?
● They go up into the stratosphere and they
destroy ozone molecules.
● CFC’s can create a thinning ozone layer
which would allow more UV radiation
through
8. Why did we develop a protocol to reduce CFC’s?
● We wanted to restore / stop destroying the
ozone layer
8.2.1 → Layers of the Atmosphere
9. List the layers in order from Outer Space to Earth
● Exosphere
● Thermosphere
● Mesosphere
● Stratosphere
● Troposphere
10. Which two layers decrease in temperature?
● Troposphere and Mesosphere
11. Which layer is the densest?
● Troposphere
12. Which layer is the least dense
● Exosphere
13. Identify which layer the following items belong
● Aurora Borealis ​→​ Thermosphere
● Humans / Animals ​→​ Troposphere
● Meteors ​→​ Mesosphere
● Ozone Layer ​→​ Stratosphere
● Planes ​→​ Stratosphere
● Satellite ​→​ Exosphere
● Space Shuttle ​→​ Exosphere
● Weather ​→​ Troposphere
● Mountains ​→​ Troposphere
● Weather Balloon ​→​ Stratosphere
8.2.2 → Ozone Layer
14. What does the ozone layer protect us from?
● Too much ultraviolet (UV) radiation
15. What can happen to humans if we have too much
UV radiation?
● Skin Cancer
● Cataracts
● Weakened Immune System
● Wrinkles
16. What can happen to plants if they get too much UV
radiation?
● Lower growth rates ​→​ Less Photosynthesis
● Lower production rates ​→​ Burning
17. What are the three different types of UV radiation?
● UVA
● UVB
● UVC
18. How much (%) of each type of UV radiation hits the
earth?
● UVA ​→​ 100% Hits Earth
● UV B ​→​ 50% ½ is blocked by the ozone
layer

We wanted to eliminate the amount of UV
radiation that hit Earth
8.2.1 → Layers of the Atmosphere
19. How would the amount of UV radiation change if
we had MORE ozone?
● Less UV radiation (UVB) would hit the Earth
20. How would the amount of UV radiation change if
we had LESS ozone?
● More UV radiation (UVB) would hit the
Earth
8.2.3 → Greenhouse Effect
21. What does the greenhouse effect protect us from?
● Freezing. It keeps the earth warm by
trapping infrared radiation
22. What path can infrared radiation take as it enters
our atmosphere?
● Reflected by greenhouse gases
● Absorbed into the earth
● Reflected by earth into atmosphere
● Reflected by earth and reflected by
greenhouse gases ​→​ Trapped within
atmosphere
23. What will happen if we increase the amount of
greenhouse gases in the atmosphere?
● More infrared radiation would be trapped
● Earth’s temperature would increase
24. What will happen if we decrease the amount of
greenhouse gases in the atmosphere?
● Less infrared radiation would be trapped?
● Earth’s temperature would decrease
25. What would happen if we didn’t have greenhouse
gases?
● No infrared radiation would be trapped
● It would be hot during the day and cold at
night
8.2.4 → Global Warming
26. Why is it important to clarify evidence?
● To get the entire picture
● To determine the authors bias and
experience
27. What clarifying questions would you ask about the
following piece of evidence?
● Evidence: Baseball is the most popular
sport for students in the United States
● QUESTIONS:
UVC ​→​ 0 % All is blocked by the Ozone
Layer
8.2.4 → Global Warming Continued
28. What clarifying questions would you ask about the
following piece of evidence?
● Evidence: Polar bears are increasing in
population and aren’t impacted by the
warming temperatures
● QUESTIONS:
● Does your data include polar bears from
around the world?
● Does it include protected polar bears (in
reservations or zoos) or polar bears who
aren’t living in their natural environment
(zoos)
● How much of an increase is it?
● Have their population been increasing for
years? Months?
29. Why is it important to identify bias?
● To get the real information
30. How do you determine if the author is biased?
● Look at their qualifications
● Determine the overall tone
● Who does the author work for
31.
32.
33.
34.
● Is the information factual
What is global warming?
● The gradual, permanent increase in earths
global temperature
What causes global warming?
● There are natural ups and downs but
human activity is also to blame
How is our CO​2​ emissions related to the global
temperature? Be very specific
● As humans emit additional CO​2​ the amount
of CO​2​ in the atmosphere increases
● As the amount of CO2​ ​ in the atmosphere
increases, additional infrared radiation is
trapped
● As additional infrared radiation is trapped
our global temperatures increase
What will happen if our CO​2​ levels continue to
increase?
● Our global temperature will increase
