When does ozone depletion occur?

Answer 1

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.

Answer 2

It has not been completely destroyed. As a matter of fact there are only two places that have thinning areas. 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.

Answer 3

Ozone depletion occurs when the natural balance between the production and destruction of ozone in the stratosphere is disrupted. This can be exacerbated by human activities that release ozone-depleting substances, such as chlorofluorocarbons (CFCs) and halons, into the atmosphere. The ozone layer is most vulnerable to depletion during the spring in the polar regions, leading to the formation of the ozone hole.

Answer 4

It occurs when we use stuff like computers, Air conditioners, freezers, and other machines that require Flouride(well toothpaste doesn't make ozone depletion but you know what I mean)

Answer 5

The destruction of the ozone layer is in stratosphere. It is due to CFC's.

Answer 6

Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.

Answer 7

Maximum ozone destruction is at poles. It is because of low temperatures.

Answer 8

when cfc's pollute the layer of it
