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.

What is the atomicity of ozone?
the atomicity of ozone is 3
hehehehe./////////////......................
Why does the ozone hole occur in the southern hemisphere?
Ozone hole occurs in the southern hemisphere. It is because westerly's carry CFC's there.
How long ago was the ozone layer created?
The ozone hole is a repeating phenomenon, that has most likely occurred since there was ozone in the atmosphere (hundreds of millions of years). The size of the hole is the issue, whether Man plays any part in making it bigger.
Oxygen in the atmosphere is O2, two atoms of oxygen. Ozone, no matter where it is in the atmosphere or in a process, is O3, three atoms of oxygen.
What happens when a molecule absorbs ultraviolet radiation?
When oxygen absorbs UV, it breaks it down. That atom then reacts again with oxygen to form ozone.
How has human influence on the environment affected humans health?
Life span has seriously increased by our ability to control our environment. Increased food production, controlling dangerous pests and using our environment to generate power are a few of the great things we have done. Controlling water flow has helped us populate areas we could not otherwise populate.
What is the importance of ozone layer to the plants?
Ozone layer helps to maintain the appropriate temperature. This helps plant grow and survive.
How does acid rain effect the ozone layer?
It doesn't. Ozone depletion is caused by CFCs and other halogen containing materials not NOx or SOx
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.
