Study Guide Questions/Daily Targets:
These questions will serve as your study guide for the Test. Use drawings/diagrams wherever necessary to help
you remember and review the information. These questions will be assigned during the course of the unit.
You may not type answers into the document. Only handwritten study guides will be accepted.. Questions
do NOT need to be answered in complete sentences.
9.1 & 9.2 - Reducing Stratospheric Ozone Depletion
1. Explain why stratospheric ozone is necessary for life.
2. Explain why tropospheric ozone is harmful to life.
3. Identify the anthropogenic, ozone-depleting compound.
4. Identify a natural cause of ozone depletion.
🎥Video Review🎥
5. Describe how ozone is depleted by the main anthropogenic ozone-depleting compound.
6. Identify ONE human health impact and ONE environmental impact of stratospheric ozone depletion.
7. Why is the ozone hole is located where it is? Or in other words, why isn’t the ozone hole above where
most of the ozone depleting chemicals are emitted into the atmosphere? (look this up)
8. What steps are being taken to reduce ozone depletion? (make sure one is more local and one is more
global)
9. Propose a solution to reduce the anthropogenic depletion of ozone.
9.3 - The Greenhouse Effect
🎥Video Review🎥
10. Identify FOUR major greenhouse gasses and their sources
Greenhouse gas
Source
11. Explain how the greenhouse effect influences the surface temperature on earth.
12. Describe the role albedo plays in the process of increasing atmospheric temperatures.
13. Explain why water is considered a greenhouse gas, but why it is not a driver of climate change.
14. Describe what the global warming potential of a greenhouse gas refers to.
15. Identify ONE greenhouse gas with a global warming potential greater than 1.
16. Describe one factor that leads to this greenhouse gas having a GWP above 1.
17. Describe the trend in global greenhouse gas emissions since the Industrial Revolution.
18. Why is there an increase and decrease in the keeling curve making it look like a zig zag?
9.4 - Increase in the Greenhouse Gases
🎥Video Review🎥
19. Explain how an increase in CO2 levels in the atmosphere can lead to rising sea levels.
20. Describe ONE environmental impact of melting glacial ice or antarctic ice sheets.
21. Explain how an increase in greenhouse gasses in the atmosphere can lead to an increase in the spread
of disease such as Malaria.
22. Describe a trend in human population relocation that may result as greenhouse gas levels in the
atmosphere increase.
23. Describe thermal expansion.

9.5 - Global Climate Change (pt. 1)
24. Identify TWO sources of data that scientists use to study earth’s climate tens to hundreds of thousands
of years in the past.
25. Describe TWO changes that occur in marine ecosystems as a result of global warming.
26. Describe the effect that global warming has on the hadley cell.
27. Describe the effect that global warming has on the polar jet stream.
9.5 - Global Climate Change (pt. 2)
🎥Video Review🎥
28. Explain how global warming may slow down or halt the thermohaline circulation of the ocean.
29. Identify a region on earth that is warming faster than earth’s average increase in surface temperature.
30. Describe why this region is warming faster than other regions.
31. Describe the importance of ice sheets and the effects of losing these ice sheets on the global climate.
32. Describe a positive feedback loop that occurs as ice sheets at the poles melt
Identify the following as positive or negative feedback loops
33. Earth warms, which increases evaporation of water from oceans, which adds additional water vapor to
atmosphere. In this case, water vapor is a greenhouse gas.
34. On a hot day, people turn on their air conditioning. The air conditions are run with electricity which is
generated in a power plant by burning natural gas. The exhaust from the power plant is CO2. With
more CO2, the atmosphere heats up more and people turn their air conditions up.
35. Earth warms and algae populations will increase. The algae will use CO2, thus depleting CO2 from the
atmosphere.
36. Earth warms and water evaporates from the ocean. The moisture condenses to form clouds. The
clouds reflect sunlight back into space.
37. Earth warms and glaciers and ice caps melt and dark terrestrial land is exposed. The dark land absorbs
sunlight.
38. List three things you could do to decrease your contribution to global climate change.
39. Explain why reducing greenhouse gas emissions requires international efforts.
40. What's the current situation with the Paris Climate Agreement and the US? (look this up)
9.6 - Ocean Warming
🎥Video Review🎥
41. Explain how an increase in greenhouse gasses in the atmosphere leads to an increase in average ocean
temperature.
42. Describe TWO consequences that ocean warming can have on marine species.
43. Describe the process of coral bleaching.
44. Describe how ocean warming can increase the frequency of harmful algae blooms.
9.7 - Ocean Acidification
🎥Video Review🎥
45. Explain how increased atmospheric CO2 levels causes ocean acidification.
46. Identify THREE human activities that lead to ocean acidification.
47. Describe the impact that ocean acidification has on shell-building marine organisms or coral.
48. Explain why carbonate ions are important for marine organisms that build shells and how ocean
acidification impacts the availability of carbonate ions in the ocean.
