The concentration of CFCs, or chlorofluorocarbons, in the atmosphere is around 0.22 parts per billion (ppb), which is significantly lower than in previous years due to international efforts to phase out their use under the Montreal Protocol. However, the residual CFCs that remain in the atmosphere still contribute to ozone depletion and global warming.

What appliances increase CFCs in the atmosphere?
Refrigerators and air conditioners are common appliances that can contribute to an increase in CFCs in the atmosphere. CFCs are used as refrigerants in these appliances and can be emitted into the atmosphere if not properly contained or disposed of.
Can rain demolish CFCs?
Rain can help remove CFCs from the atmosphere by acting as a natural cleanser. When CFC molecules are exposed to rain, they can react with water and break down into less harmful compounds that are eventually washed out of the atmosphere.
What is ozone later?
Ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone molecules. It plays a crucial role in absorbing the majority of the sun's harmful ultraviolet radiation, protecting life on Earth. However, human activities have led to ozone depletion, particularly due to the release of chlorofluorocarbons (CFCs) into the atmosphere.
How do you CFCs illustrate that technical knowledge can be a double edged sword?
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
Which one of the chemical is responsible for the reduction of Ozone content of the atmosphere?
Chlorofluorocarbons (CFCs) are primarily responsible for the reduction of ozone content in the atmosphere. When released into the atmosphere, CFCs break down ozone molecules in the stratosphere, leading to the thinning of the ozone layer.
How are cfcs released?
CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.
What appliances increase CFCs in the atmosphere?
Refrigerators and air conditioners are common appliances that can contribute to an increase in CFCs in the atmosphere. CFCs are used as refrigerants in these appliances and can be emitted into the atmosphere if not properly contained or disposed of.
What is the protective layer of the atmosphere destroyed by CFCs?
ozone
Can rain demolish CFCs?
Rain can help remove CFCs from the atmosphere by acting as a natural cleanser. When CFC molecules are exposed to rain, they can react with water and break down into less harmful compounds that are eventually washed out of the atmosphere.
Is there a tree which can absorb CFCs?
No, trees do not absorb CFCs (chlorofluorocarbons). CFCs are synthetic compounds used as refrigerants that are primarily broken down in the atmosphere by sunlight. Trees primarily absorb carbon dioxide, not CFCs.
What gas is present in the atmosphere of venus that explain its high surface temperature?
high concentration of carbon dioxide
Are humans responsible for the depletion of the ozone layer?
Yes. People developed chemicals such as CFCs (Chlorofluorocarbons) for use in refrigerators and as a propellant gas in aerosols. These CFCs rose high into the atmosphere and caused damage to the ozone layer. the use of CFCs has since been banned and the ozone layer is slowly recovering. Hopefully.
What kind of effect do CFCs - chlorofluorocarbons - have on the atmosphere?
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.

How do chlorofluorocarbons build up in the atmosphere?
Chlorofluorocarbons (CFCs) build up in the atmosphere when they are released from products like refrigerants and aerosols. Once in the atmosphere, CFCs break down and release chlorine atoms, which then catalyze the destruction of ozone molecules in the ozone layer.
