If the ozone is thinning, it will lead to ozone hole. It allows the harmful UV to pass through.
They think that because of its components. It contains Chlorine which depletes the ozone.
It is a measure of depleting chemicals. We have staff near the South Pole, and they can do this monitoring too.See "What makes scientists think the ozone layer is thinning?"
Scientists believed that chlorofluorocarbons (CFCs) released into the atmosphere could break down the ozone layer due to their ability to release chlorine atoms when exposed to ultraviolet light. These chlorine atoms can then destroy ozone molecules, leading to thinning of the ozone layer. This theory was supported by observations of higher levels of chlorine in the stratosphere where the ozone layer is located.
One of the factors that scientists believe is contributing to the destruction of the ozone layer is the release of certain chemicals called ozone-depleting substances, such as chlorofluorocarbons (CFCs) and halons. These chemicals break down ozone molecules in the stratosphere, leading to the thinning of the ozone layer.
The ozone hole primarily forms over Antarctica due to human-made chemicals called chlorofluorocarbons (CFCs) and halons that break down ozone molecules. This depletion, which occurs mainly during the Southern Hemisphere's spring, has been a significant environmental concern since the late 20th century.
They think ozone is disappearing. It is because of increased UV radiations.
Ozone is found in the air. By the way, I don't think there is such thing as good ozone.
Ozone is formed over the equator. It is because ozone forms in hot areas.
I think the question says ozone depletion. Ozone depletion is the destruction of ozone molecules. These molecules are made of oxygen. O3 is the chemical formula.
Ozone is the common name for oxygen oxide.
Ozone is disappearing. It is because of the increasing CFC's.
We know that the most, if not all, of the thinning of this layer occurs during the solar winter at each pole. We also know that the location is due to the tilt of our planet. We know ozone s very unstable and needs sunlight hitting this layer at all times or the layer starts to thin (or disappear). There is no question that this has occurred since the beginning of the planet. This is a very natural event. The problem comes in with a few man made gases. Most are CFC's used for cooling systems. There are minor gases as well such as methane. These are all much heavier then air but are found in extremely small quantities, in this area despite this weight. These gases are very reactive with ozone and can create other combinations of gas from ozone thus thinning the layer. The layer we are talking about is very thin, about 3mm thick. The fear is that before we can understand if this is an issue, it could be gone. Bans have been placed to limit the use of CFC's until we understand the issue better.
