What is the effect of CFCs on stratospheric ozone?
Protects the stratospheric ozone
Depletes the stratospheric ozone
Enlarge the stratospheric ozone
Helps ozone formation
- 8. Multiple-choice30 seconds1 pt
The treaty signed under the direction of UNEP to reduce the use of CFCs was called The Montreal Protocol (1987)
True
False
- 9. Multiple-choice30 seconds1 pt
The “Montreal Protocol on Substances that Deplete the Ozone Layer” has been effective in reducing CFC emissions
True
False
- 10. Multiple-choice30 seconds1 pt
What is ozone?
Ozone is made of 3 oxygen atoms, and when it is in the stratosphere it protects Earth
Ozone is made of 2 oxygen atoms and when in the troposphere it protects the Earth
Ozone is made of 2 oxygen atoms and when in the stratosphere it harms the Earth
Ozone is made of 3 oxygen atoms and it all throughout the atmosphere
- 11. Multiple-choice30 seconds1 pt
How is Ozone formed?
Formed from UV radiation splitting CO2
Formed as a stable gas that doesn't change form from 2 oxygen atoms
Continuously formed and destroyed via UV radiation from oxygen atoms and molecules
Formed from all components in the atmosphere (CO2, argon, nitrogen)
- 12. Multiple-choice30 seconds1 pt
What are the adverse effects of UV light on biological organisms?
Has no other adverse health effects except suppression of the immune system
There are none
It doesn't harm humans, just phytoplankton and zooplankton
Damages cataract formation, causes skin cancer, damages photosynthetic organisms, and damages consumers of photosynthetic organisms
- 13. Multiple-choice30 seconds1 pt
What are the effects of reduced phytoplankton primary productivity?
Beneficial , there are too many phytoplankton that are damaging other population numbers
Negative, if the primary productivity of phytoplankton is reduced the productivity of the entire ecosystem is reduced
Negative, the phytoplankton are needed to outcompete whales in krill eating
Beneficial, they eat the whales that harm other animals
- 14. Multiple-choice30 seconds1 pt
Why is the ozone layer important?
It helps us tan
Without the ozone layer no sunlight would get through
It protects us from excessive harmful ultraviolet light
The ozone layer re-radiates light and cools down our planet
- 15. Multiple-choice30 seconds1 pt
Which of the following is used in fire extinguishers?
Methyl Bromide
HCFCs
Halons
CFCs
- 16. Multiple-choice30 seconds1 pt
What specific chemical harms the ozone molecules?
Argon
Chlorine
Neon
Iridium
- 17. Multiple-choice30 seconds1 pt
Which of the following alter human activity?
Recover and recycle CFCs
National legislation
Replace glass blown plastics
Add ozone to the stratosphere
- 18. Multiple-choice30 seconds1 pt
What was the Montreal Protocol?
An agreement between several countries on ozone depleting substances
A conference about the ozone layer
A court case about ozone depleting substances
- 19. Multiple-choice30 seconds1 pt
Which equation demonstrates ozone formation and destruction?
O + O ⇌ O2
O2 + O ⇌ O3
O2 + O → O3
O3 → O2 + O
- 20. Multiple-choice30 seconds1 pt
Which types of UV lights promote photosynthesis?
I - UV-A
II - UV-B
III UV-C
I & II
II & III
I & III
I, II, III
- 21. Multiple-choice30 seconds1 pt
What a result of reduced productivity of phytoplankton?
5% will be transferred between energy levels
Carrying capacity will improve
UV-C rays will be absorbed and so the ecosystem will be protected from them
The food chain will be destabilised/ reduced resilience
- 22. Multiple-choice30 seconds1 pt
What protects the world from harmful UV radiation?
Ecosystem resilience
Eutrophication
