Ozone Layer
The ozone layer is a crucial layer in the Earth's atmosphere that absorbs and blocks out harmful ultraviolet light that can damage Earth.

Why was a ban on CFCs necessary?
Ban on CFC's is a necessity. The ban is necessary because of the harmful effects.
Why did Joe Farman delay publishing his results of ozone depletion for 2 years?
Joe Farman delay his publishing for 2 years. It is because he wanted his studies to be accurate.
Do the ozone hole increase carbon dioxide in the atmosphere?
Indirectly yes. It causes global warming, which increases carbon dioxide in the atmosphere.
Sentence with the word ozone hole?
When it is winter at the South pole, the ozone naturally decays forming an ozone hole.
Halons and CFC s both destroy ozone in the stratosphere.
What makes pollution break the ozone layer?
Pollution can break the ozone by global warming. This can then cause ozone depletion.
Which layer contains the most gases?
80 percent of the gas in the atmosphere reside in the troposphere.
Why we as a planet banned cfcs?
We have to ban CFC's because of their adverse affects. They affect the ozone by depleting them.
Tropospheric ozone is ozone produced by:
- Lightning, and background ionizing radiation,
- Discharge from power lines and electrical applicances,
- Photoproduced from the combustion byproducts NOX and VOC
In areas such as the American and Canadian plains there isa significant amount of ozone added to the troposphere by down washing of stratospheric ozone as winds pass over high mountains such as the Rockies,
Ozone depletion is the lowering of ozone layer's concentration. It is due to CFC's.
What are two effects that will most likely occur if the ozone continues to be destroyed?
If ozone is destroyed, there will be no life on earth. Also the temperature of earth will increase.
Why is halon harmful for ozone layer?
Halons are harmful for ozone. They also react with ozone to deplete it.
Is ozone evenly distributed throughout the atmosphere?
No. It is at its minimum at Earth's surface (where there is little energetic sunlight to make more, and plenty of things that cause it to decay), and in the exosphere (where there is so much energy almost everything is missing an electron or two, and collisions between atoms are too energetic to allow many captures). It has a maximum in the lower stratosphere, where UV-C shatters nitrogen and oxygen, and some of the oxygen later forms ozone.
Annually, each pole develops an "ozone hole" in late winter / early spring. Here the amount of ozone is reduced quite a bit by various sorts of contaminants... some sourced by Nature and some by Man.
What chemical caused damage to the ozone layer over Antarctica?
The chemical that cause ozone hole over antarctica is CFC. Chlorofluorocarbons are the ones that contain chlorine which deplete ozone layer.
What are the impacts on ozone layer?
The ozone layer acts as a shield on the earth. It protects us from the harmful UV rays of the sun.
What are the common products likely to contain ozone depleting substances?
Not many left. Used to be refrigerants, solvents, propellants (like in spray cans), and stuff for inflating foam products.
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 causes ozone pollution levels to increase?
The ozone is a pollutant at ground level. It is a greenhouse gas too. Phenomenon like lightening, smog etc increase ozone pollution levels to increase.
Ozone in the lower atmosphere has three causes:
- Electrical discharges like lightning
- As part of the photochemical smog creation process
- As adown washing of stratospheric ozone as winds blow over mountains
What is the ozone layers cause?
Ozone layer protects the earth from UV rays. These are fatal rays of the sun.
What do most people know about recycling?
The thing most people know about recycling it to reuse the substances. A thing once used, should be thought of using in some other way.
Why do you think scientists environmentalists and politicians are arguing about global warming?
Scientists and environmentalists are warning the world that global warming is a real and present danger.
Politicians can rarely see beyond the next election in three or four years. Few of them, in the US anyway, have any long term vision.
What is absorbed by OZONE in the statosphere?
OZONE in stratosphere helps to absorb the harmful ultraviolet radiations coming from sun. These are very harmful high frequency waves. This ozone is present as ozone layer in the stratosphere.
Why is it dangerous when ozone is near Earth's surface?
Ozone is a protective substance at the atmosphere level. It can be dangerous as a pollutant at the level of ground.
What are the reactions involved for ozone layer depletion in the stratosphere?
The reactions involve ozone getting decomposed. This causes a chain reaction.
