What man made pollutant destorys the ozone layer?
Chlorofluorocarbons (CFCs) are man-made pollutants that destroy the ozone layer. Once released into the atmosphere, they break down and release chlorine, which then reacts with ozone molecules, leading to the depletion of the ozone layer.
Why is the ozone layer damaged from below?
The ozone layer is damaged from below due to the release of ozone-depleting substances like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) at the Earth's surface. These substances are released by human activities such as industrial processes and use of certain products like refrigerants and aerosol sprays. Once released, these substances rise into the atmosphere and break down ozone molecules in the stratosphere, leading to ozone layer depletion.
Chemical responsible for ozone layer depletion?
Chlorofluorocarbons (CFCs) are the main chemicals responsible for ozone layer depletion. Once released into the atmosphere, CFCs can reach the stratosphere where their chlorine atoms can destroy ozone molecules.
How do you prevent holes in ozone layer?
The ozone hole is a natural occurrence. You cannot prevent it. You might keep it from starting sooner, have more ozone in it, or from lasting longer.... but you cannot stop it from forming once a year at each pole when it is late winter / early spring there.
What damages the ozone the most?
Chlorofluorocarbons (CFCs) and halons are the main substances that damage the ozone layer the most. These chemicals are released from activities like refrigeration, air conditioning, and aerosol use. Once released into the atmosphere, they can degrade the ozone layer, leading to ozone depletion.
Is the ozone layer a finite resource?
The ozone is a finite resource. It once destroyed, that molecule is lost.
What man made pollutant destorys the ozone layer?
Chlorofluorocarbons (CFCs) are man-made pollutants that destroy the ozone layer. Once released into the atmosphere, they break down and release chlorine, which then reacts with ozone molecules, leading to the depletion of the ozone layer.
What human chemical can destroy the ozone layer?
Chlorofluorocarbons (e.g. freons - as once used in spray cans, refrigerators, freezers, and air conditioners). They rise through the atmosphere to the ozone layer where UV decomposes them, releasing the chlorine gas which catalyzes the destruction of ozone in that layer. These chemicals have been phased out as much as possible, replaced by hydrochlorofluorocarbons (which decompose nearly completely in the lower atmosphere, never reaching to ozone layer) or fully fluorinated fluorocarbons (which contain no chlorine, fluorine gas released in the ozone layer does not catalyze ozone destruction).
Why is the ozone layer damaged from below?
The ozone layer is damaged from below due to the release of ozone-depleting substances like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) at the Earth's surface.

Once released, these substances rise into the atmosphere and break down ozone molecules in the stratosphere, leading to ozone layer depletion.
Does air pollution come from the ozone layer?
no it comes from us and goes to the ozoneAnswer:Studies downwind of the Rockies in ALberta show that stratospheric ozone can be downwashed to the surface (troposphere), once at that level ozone is a pollutant.
What damages the ozone layer the most?
Chlorofluorocarbon gases (CFCs) eat the ozone layer alive where we use it everyday for industrial processes although the ozone layer can repair Itself. Another answer: The number one reason ozone thins in our atmosphere is due to a lack of sunlight. Without this energy, ozone naturally will decay into oxygen molecules. This is why the hole in the ozone layer only appears over the poles and then only at the end of the winter months at each pole. Once the sun returns, these holes quickly disappear.
Why ozone layer depleted in poles rather there is no pollution there?
Pollution is not a ozone layer issue. The "hole" in the ozone layer is a thinning of the layer (mostly above the South Pole) that occurs each year for a short period (about 4 months total cycle) because the sun is unable to hit the layer. Ozone is a very unstable element and with energy from the sun it degrades into simple oxygen (O2). The layer is normally about 3 mm thick and once a year, when the sun can not hot the layer, it degrades to about 1 mm.There is some trace amounts of a few items such as CFC's in this area. These gases do have the ability to react with ozone.

When was the massive hole in the ozone layer over the Antarctica first discovered?
The ozone hole first appeared when the ozone layer first appeared. The only variable is the "size" of the hole, and the ozone concentration in the "hole". The pole of the Earth that is experiencing winter receives none of the UV that makes ozone (for like a month or more), and ozone naturally decays with time. TThe ozone hole is a normal feature of our ozone layer. It appears each year when it is winter at one of our poles. So it first appeared when the ozone layer appeared. We first noticed the ozone hole in 1985, above Antartica. One forms over the Arctic pole too when it is winter there. They heal closed again once sunlight reaches the pole. Its not so much the presence or absence of an ozone hole, but its size that is important. It is important to look out for the ozone hole
Are cfc stable?
CFCs (chlorofluorocarbons) are not stable in the atmosphere. Once released, they eventually break down into molecules that harm the ozone layer. This depletion of the ozone layer contributes to global warming and increases the risk of harmful UV radiation reaching the Earth's surface.
