What is the correct equation for the breakdown of ozone?
O3 + UV ---> O3 + energy
O3 + UV ---> O2 + O
O2 + O + UV ---> O3
Ozone cannot be broken down

Carbon
Hydrogen
Oxygen
Nitrogen
CFCs are responsible for the damage caused to the ozone layer. Select ALL of chemical elements make up CFCs.
Carbon
Hydrogen
Oxygen
Fluorine
Chlorine
What harmful health effects do scientist say that the UV radiation that passes through our "shield" will cause?
increase in skin cancer
immune deficiencies
cataracts
all of the answers
What happens to form ozone gas?
Oxygen molecules interact with the UV rays from the Sun.
Chlorine molecules interact with the UV rays from the Sun.
Oxygen and chlorine molecules produce a gas.
What are "holes" in the ozone layer?
places where the ozone concentrations are lower than under normal conditions, allowing more UV radiation to reach the Earth's surface.
places where the ozone concentrations are higher than under normal conditions, allowing more UV radiation to reach the Earth's surface.
places where the ozone concentrations are higher than under normal conditions, allowing lessUV radiation to reach the Earth's surface.
Which of the following is the most common ozone destroying pollutants?
Chloroflurocarbons
particular matter
Nitrogen dioxide
carbon monoxide
The ozone destroying pollutants primarily comes from air conditioner coolants, refrigerator coolant, aerosol spray, and plastic foam.
true
false
What is the name of the international agreement committing parties to phasing out ozone depleting substances and phasing down hydrofluorocarbons (HFCs)?
Vienna Protocol
Paris Agreement
Montreal Protocol
Antarctic Convention
Where is the 'hole' in the ozone layer located?
Over the United States
Over Europe
Over Antarctica
Around the equator
Which of these sets of three items produce CFCs
cars, factories, and cardboard
spray cans, cardboard, insulation
spray cans, refrigerant, cardboard
spray cans, refrigerant, insulation
Where is the "GOOD" ozone located?
troposphere
stratosphere
mesosphere
thermosphere
Which is not an example of an ecological consequence of reduced stratospheric ozone?
loss of biodiversity from reduced photosynthesis in plants
collapse of marine food webs
increased crop yield
reduced terrestrial biome productivity
Which statement regarding the decreased level of stratospheric ozone is correct?
Increased photosynthetic activity has been measured in the phytoplankton around Antarctica
The largest decrease in the level of stratospheric ozone over the Arctic region occurs between January and April
Although the Montreal Protocol led to a reduction in the use of CFCs, it will have little effect on stratospheric ozone levels in the long term
There is no correlation between the incidence of cataracts and skin cancers and the lower level so stratospheric ozone
The global crop yields of wheat, rice, and corn have increased since the reduction in CFC use
Which is true about ozone formation and destruction? select all that apply
Its formation and destruction is an example of a dynamic process in nature.
It forms when a free oxygen atom reacts with a molecule of oxygen.
UV radiation breaks up ozone by splitting off an oxygen atom.
Ozone cannot reform once it absorbs UV radiation.
Why was the Montreal Protocol so successful? (3)
What is the relationship between volcanic eruptions and ozone depletion? (2)
What is the difference between climate change and ozone depletion? (2)
