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.
What else can I help you with?
Why did scientists think that the thinning of the ozone layer might be related to CFCs?
They think that because of its components. It contains Chlorine which depletes the ozone.
Why did scientists think that the thinning of the ozone layer might be related to CFC's?
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.
What year do scientists think the ozone layer will have rebound?
Scientists hope the ozone layer will have recovered by around 2050.
What is one of the factors scentists think is contributing to the destruction of the ozone layer?
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.
What does scientist think is damaging the ozone layer?
Accouring to the scientists, the main cause of depletion of ozone layer is the use of CFc's. These CFCs react with ozone present in the ozone layer and deplete it.
What makes scientists think that ozone layer disappearng?
There have been various experiments measuring the ozone layer. The ozone over the poles is seen to have depleted.
What do you think will happen if the thinning of ozone continue?
If the ozone is thinning, it will lead to ozone hole. It allows the harmful UV to pass through.
Why should you continue to monitor 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?"
What is one of the factors that scientists think its contributing to the destruction of the ozone layer?
The main reason that scientists think is contributing to destruction of ozone depletion is the use of CFC's. These are chemicals present in various substances and when released destroy ozone molecules.
What makes scientists think that the oxone layer is dissapearing?
It is because of CFC's. They react with ozone to deplete it.
What make scientist think that the ozone layer is disappearing?
Scientists believe that the ozone layer is disappearing because there is a large hole in it. This hole was not there years ago.
What makes scientists think that the ozone layer is disapperance a problem?
Ozone disappearance is a problem. It is because it allows the UV rays to pass through.
