What else can I help you with?
What is abbreviation for ozone hole?
There isn't any abbreviation. Ozone hole is the decrease in the concentration of ozone molecules.
Is there any hole in the ozone layer now currently?
The ozone hole is in the south pole. It is over Antarctica.
Is there any hole in ozone layer?
yes
Is there any hole in ozone how is it?
Yes there is a hole. It is the thinning below a certain concentration.
What is the effect of ozone layer on stratosphere?
Ozone layer is present in stratosphere. It does not cause it any effect.
Is the hole in the ozone layer getting larger?
yesbut in some parts theres no hole but the ozone is too thickThe ozone hole this (2009) winter/spring (south pole) was a little smaller than the record size. Whether Man had any part in that "improvement" through his efforts remains to be seen. Note that the ozone hole is an annual repeating phenomenon at each pole, and the southern ozone hole is naturally larger than the northern ozone hole.
How does the hole in the ozone layer affect weather?
Ozone is a naturally occurring greenhouse gas that helps keep the earth warm. Therefore the depletion of the ozone layer had a minor cooling effect on the world, although more than compensated for by the rise in carbon dioxide levels. Because the depletion was concentrated in the Antarctic region, this is believed to have contributed to altered wind wind patterns. The main problem with depletion of the ozone layer was not so much any effect on the weather, but the potential effect on our health, through excessive exposure to ultraviolet light.
Does global warming cause the ozone hole?
No. There is hardly any connection between the ozone layer and global warming.
How have we helped to cause the hole in the ozone layer?
The ozone hole is a natural, repeating occurence. See "How did the ozone hole occur?"We may or may not make it "deeper", start sooner, get larger, last longer, but we do not have any part in making the hole. Nature does that on her own, when it is later winter / early spring at a pole.
Why is the ozone hole a seasonal event?
Ozone in the ozone layer is made by UV-C from our Sun breaking apart oxygen molecules, some of these oxygen atoms form ozone when interacting with whole oxygen molecules. Ozone is naturally unstable (decays with time), and contaminants (H2O, Cl, Br, etc) accelerate the decay of ozone. The ozone hole forms when the pole stops getting UV-C from the Sun, and ozone decays away (for the various reasons above). The ozone that is there, is largely "long lived" remnants, ozone that has diffused in from adjacent regions, and ozone formed by cosmic rays from space. The ozone hole starts healing in the spring, when UV-C from the Sun starts arriving and ozone is made. By summer, ozone has reached its peak equilibrium concentration. UV-C from the Sun is now striking the atmosphere over the pole, now that it is spring there, and the ozone hole heals shut by summer. The ozone hole is a natural occurance, that occurs once a year at each pole. The southern polar hole is larger than the northern polar hole due to Earth's current magnetic alignment. The *size* of the hole is what is of concern... and something that the affairs of Man can play a part in. Ozone decays naturally with time. With the axial tilt that Earth has, once each year (local winter) each pole stops receiving the UV-C that turns some oxygen into ozone. So the ozone starts decaying, and a hole forms. The only ozone the pole gets at this time, diffuses in from areas that are still receiving UV-C. So the ozone would be exceedingly thin at this time. Add contaminants to the mix, and the amount of ozone drastically decreases. Water vapor (natural and Man-sourced), chlorine (most commonly Man-sourced, carried by CFCs), and bromine (most commonly natural, but likely some Man-sourced, carried form example in halon) all have shown abilities in depleting ozone. The ozone hole was discovered by Joseph Farman, Brian Gardiner, and Jonathan Shanklin in 1985. But no reason to believe that it has not existed as long as Earth has had an ozone layer (to have a hole in), an axial tilt (for winter, loss of UV-C which makes ozone), and a magnetic field (to make one hole larger than the other). The concentration of ozone at any point is a balance of incident UV-C from the Sun (both making and destroying ozone), UV-B from the Sun (destroys ozone when absorbed), time, and compounds that can accelerate the decay of ozone. The ozone holes are a natural phenomenon, and some sort of "ozone hole" will form at the pole that is experiencing winter. As spring arrives, UV-C from the Sun arrives and makes ozone... "healing" or filling the hole. The issue with ozone depletion is how little ozone is in the "ozone layer", due to the effect of contaminants. These same contaminants control how big the hole is, how little ozone there is still left in the hole, and how long it takes to heal up. During winter, the atmosphere above the pole receives no UV-C from the Sun to make new ozone. So the ozone decays both naturally, and as a result of contaminants up in the atmosphere with it. So the equilibrium value of ozone above the pole depends on diffusion from adjacent areas that are still making ozone. Spring, summer, and fall, the ozone hole heals up, is essentially non-detect, then slowly starts forming again.
Are there any countries that have a hole in the ozone layer?
The ozone hole is mainly located over Antarctica, forming during the Southern Hemisphere's spring. The hole was first discovered in the 1980s and is primarily caused by human-produced chemicals like chlorine and bromine interacting with ozone in the stratosphere. While the hole has been shrinking due to international efforts to phase out ozone-depleting substances, it still poses a threat to the environment.
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.
