Why is there an Ozone layer hole in Antarctica while there's no people, cities and of course pollution there ?

Question

As you guys all know, there are not such big cities like New York in Antarctica, but how come the ozone layer has a hole there ? I am asking in wonder, could anybody kindly to help me ?

Answer 1

When an ozone molecule absorbs UV radiation, the energy in the radiation causes the ozone molecule to break up. Normally that's no big deal, because ozone is being created and destroyed all the time, and usually the atmosphere evens things out over the whole world.

But in the arctic and particularly the antarctic, every spring a weather phenomenon call the polar vortex forms. This vortex acts like a kind of atmospheric wall around Antarctica, and prevents air from the rest of the planet from mixing with antarctic air. Than means when incoming UV breaks apart ozone in the antarctic spring, no ozone from the rest of the planet can get in to fill the gap. So the ozone in the antarctic keeps depleting, until the vortex breaks up in the summer.

Answer 2

The ozone layer is made by the collision of the solar winds and the earths magnetic field . It is very high up,nothing from down here can affect it. The hole is made by the earth tilt and the bata particles are attracted to the north pole and makes it negative. The alfa particles are attracted to the south pole and make it positive. This charge is huge and is what holds the O3 in place. At the same time these particle streams blows holes in the ozone layer.

Answer 3

The "hole" in the atmosphere over the Antarctic just happens to be where the depletion has collected. All the pollutants emitted into our atmosphere (from larger urban areas) damage the ozone (O3), splitting it into O2 and O. The O3 is what protects our planet. The O2 and O, not so much. This lack of O3 is more prevalent over the Antarctic.

Answer 4

The real answer is that the sun creates ozone in our outer atmosphere. Ozone has a very small half life meaning it will turn to O2 (normal oxygen) very quickly. Since there is far less sunlight in Antartica, (it is at an extreme angle), there is far less ozone produced. This wierd psychobabble about it migrating there is just people trying to push their junk science of man is bad and responsible for everything bad. Man is probably not to blame at all in my opinion.

Answer 5

every planet that has an atmosphere has 2 holes ... its called a gravity feild....

some people think that it is man-made.. kinda like global warming.. but both are... not true

the holes in the ozone layers can be tracked back more than 1 million years. with core ice from the artic it has always been there... but some people say it is getting bigger... I dunno...
i do know the earth has lost its atomosphere 9 or 10 times in its history.. and that was long before humans exsisted..

Answer 6

I think that there is a certain amount of ozone-depleting stuff in the atmosphere (that is evenly spread out all over the globe) that is more active near the south pole because of environmental conditions.

Answer 7

It's the way that the atmosphere works on this planet.
