Ozone is destroyed by:
* UV-B and more energetic light, * time, * temperature, * water vapor, * CFCs and other contaminants For the ozone layer, the light is mostly when the Sun is shining on that bit of atmosphere. For the ozone layer, the CFCs and other contaminants require sunlight to do their thing as catalysts (which is why the largest "ozone hole" occurs in early springs, and sunlight is returning). The other three work continually, and do not require light.

These are over each of the poles, with the largest occurring during the winter months at the south pole. These "holes" have occurred since we have had ozone in the atmosphere and are caused primarily due to a lack of sunlight. This is why they completely heal themselves when the sun comes back to that area in the spring.
Solar variation and plasma discharges are the primary cause of ozone depletion outside the lack of sunlight. This is why the greatest thinning of the ozone layer occurred during the solar discharges of the 1859 era.
Man's incorrect use of cfc's may also have some impact on the layer. Trace amounts of CFC's have been noted in the atmosphere and certainly would have a detrimental impact on the amount of ozone in our atmosphere.

How does ozone depeletion occur?
Ozone depletion occurs by CFC's. they react with ozone to deplete it.
Ozone depletion occurs in the?
Ozone depletion occurs in the ozone layer.
What causes ozones deption?
See "What are the causes and effects of ozone layer depletion?" in the "Related questions" section below.
How does ozone depletion work?
Ozone depletion is due to CFC's. They react with ozone to deplete it.
Why does more ozone depletion occur over northern hemisphere?
Ozone depletion does not occur more over the northern hemisphere than anywhere else. More people with money for instrumentation, access to publication channels, and over-the-pole aircraft flights occur in the northern hemisphere.
How does ozone depeletion occur?
Ozone depletion occurs by CFC's. they react with ozone to deplete it.
When does most ozone depletion occur?
No they don't. Animals do nothing to harm ozone.
Why did ozone layer depletion occur in Antarctica?
It is because ozone depletion takes place in cold regions. Antarctica is the one place where ozone hole has been noticed.
Ozone depletion occurs in the?
Ozone depletion occurs in the ozone layer.
What is definition of Ozone layer depletion?
Ozone depletion is the depletion of ozone molecules. It is happening because of CFC's.
What is the mjor cause of the ozone depletion?
The major cause of ozone depletion is the reaction of CFC with ozone. They decompose ozone and cause its depletion.
What causes ozones deption?
See "What are the causes and effects of ozone layer depletion?" in the "Related questions" section below.
What does zone depletion refer to?
Ozone depletion refers to the depletion of ozone molecules. These molecules are present in the ozone layer.
What are the solutions the depletion of the ozone layer?
The solution for ozone depletion is curbing CFC's. They could prevent ozone depletion.
How does ozone depletion work?
Ozone depletion is due to CFC's. They react with ozone to deplete it.
Why does more ozone depletion occur over northern hemisphere?
Ozone depletion does not occur more over the northern hemisphere than anywhere else. More people with money for instrumentation, access to publication channels, and over-the-pole aircraft flights occur in the northern hemisphere.
Does the atmosphere prevent depletion of the ozone over Antarctica?
The atmosphere does not protect the ozone depletion. It is the region where the ozone depletion occurs.
