What is ozone thinning?
This is a thinning (by about 2/3, of the ozone over the Antarctic during the spring time, towards the end of the long winter night in the south pole. There is no actual hole in the layer. This has occurred for centuries, in fact the thinnest we know the layer has ever been is in 1858, before man started using cfc's. A similar thinning occurs, to a much smaller extent in the Arctic during the end of it's winter night also. The thinning is much smaller in the Arctic and NASA even reffers to this thin area as the "Dimple" due to the small size.
Is the hole in the ozone layer the same as global warming?
Yes, they are very similar. Ozone depletion is caused by man (CFCs), and is the overall thinning of the ozone. The "hole" in the ozone layer is over the Antarctic and it is a thinning layer where approximately 66% of the ozone disappears. The hole appears over the Antarctic because ozone needs sunlight to form and the dark and cold Antarctic winters (much colder than Arctic winters) form ideal conditions for ozone depletion and thinning.
Is most of the ozone in the earths atmosphere located in the ionosphere?
No, most of the ozone in Earth's atmosphere is located in the stratosphere, which is the second layer of the atmosphere. The ionosphere is located much higher in the atmosphere and is composed of ionized gases, not ozone.
Ozone layer depletion is an example of what kind of feedback loop?
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
The layer protecting the biosphere from too much uv?
The ozone layer acts as a protective shield in the stratosphere by absorbing and filtering out the majority of the sun's harmful ultraviolet (UV) radiation. This helps prevent overexposure to UV rays, which can cause skin cancer, cataracts, and other health issues in living organisms. Human activities that release ozone-depleting substances, such as chlorofluorocarbons (CFCs), have led to thinning of the ozone layer, highlighting the importance of preserving this protective barrier for the biosphere.

What hurt the ozone layer?
A lack of sunlight is the primary driver of the thinning of this layer. That is why we only see the thinning during the winter months over each pole. Solar activity is another primary driver of this thinning. The largest hole we know of was during the solar flares of 1858. Some believe that CFC's have some contributory effect. CFC's are much heavier then air, yet are a rare gas in this portion of our atmosphere. In the stratophere, ultraviolet light reacts with the CFC molecules to produce chloride ions. These chloride ions act as a catalyst for the breaking of the ozone (O3(g)) gas to normal oxygen gas (O2(g)).
How can you stop the thinning of ozone layer?
Don't use items that involve adding harmful gases into the air because they can affectively burning holes into the Ozone layer. Such as: petrol powered lawnmowers, cars as much. To help with this: cut your grass only in the summer once or twice every other month. And to stop using cars as much ride a bike, walk or car share to the shops,work, school, etc.
Is the concentration of ozone in polluted areas typically much higher than it is in the ozone layer?
No, the concentration of ozone in the ozone layer is typically much higher than in polluted areas. The ozone layer is composed of a concentrated layer of ozone high up in the stratosphere, whereas ozone in polluted areas is formed closer to the ground as a result of chemical reactions between pollutants.
What is threatening the ozone layer?
The sun's solar activity has a large impact on the ozone layer. So much so, that a lack of sun hitting the ozone layer near each pole in the winter months causes a thinning we refer to as a hole. This natural event heals itself shortly after the sun returns. A large enough solar flare could cause major issues with this layer, as it did n 1859 (the year of our largest ozone layer "hole"). The use of CFC's is also believed, by some, to help enlarge this event.
What are the 3 of the solutions to the problem of ozone depletion?
The issues would require that there be a problem if depleting ozone. The ozone layer does have two holes in it. One is over the Antarctic at the end of the winter when the sun has not created any ozone for months. The other thinning area is referred to as the dimple because it is so small and over the Arctic during it's winter. Both are due to a lack of sun during the winter months. The hole is much smaller today then in 1858 which was the largest recorded thinning of the ozone layer. This was before CFC's and due exclusively to solar flares. The current environmentalist claim to your ability to help the ozone layer though is to not use aerosols, not use air conditioning and generally avoid CFC's.
Why do you have a ozone layer?
Whether you believe man has anything to d o with the thinning of the south poles ozone or not, you should care about this layer. Without this layer we would have severe problems with too much UV-B. The ozone layer is absolutely responsible for the ability of life to exist on this planet.
When was the first hole in the ozone layer found?
The first hole in the ozone layer was discovered in 1985 over Antarctica by British scientists using data from satellite observations. This led to the establishment of the Montreal Protocol in 1987, an international treaty aimed at phasing out the use of ozone-depleting substances.
