Ozone Depletion - Control Flashcards
What must be reduced inorder for the ozone layer to be replenished?
A reduction in the use of CFCs will eventually allow the ozone layer to be replenished
How is ozone formed naturally?
Ozone is formed naturally by the reaction of ultraviolet light with oxygen.
What are CFCs being replaced with?
They are being replaced with other chemicals such as hydrofluorocarbons (HCFs)
Why are CFCs being replaced with HCFs?
HCFs break down faster than CFCs. So, they don’t reach the upper atmosphere and therefore do not cause ozone to break down.
What can people do to reduce ozone depletion?
Sprays or foam products that contain CFCs should not be used.
Fridges should not be dumped in landfill sites. They should be returned to organisations that will dispose of their CFCs in an environmentally friendly way.
