There are not two gases in the layer but one. Ozone is the only gas present in the ozone layer.
Greenhouse gases and pollution
Ozone is itself a gas~ ....a two molecules of oxygen make up the gas we refer to as ozone. The ozone layer is just like the rest of the atmosphere, roughly 78% nitrogen, 21% oxygen, the usual trace gases. The water vapor is markedly less than elsewhere, and the ozone level is increased to about 9 ppm (at peak value).
Ozone depltion is caused due to CFC's and greenhouse gases. It could cause skin cancer and cataract.
it describes two distincts, but related observations
The ozone layer consists of only one thing. And that thing is ozone.
Ozone layer has many holes in it. However it has a considerable major hole in it above Antartica continent. It is formed due to CFC gas. Beacuse of the hole there is an increase in the temperature of earth.
The ozone layer lies in the stratosphere. It does not lie between 2 layers. Some ozone is there in troposphere.
The two most abundant gases in any layer of the atmosphere are nitrogen and oxygen. In the stratosphere, ozone composition increases from 0.04 parts per million in other layers to 5-12 ppm. However, this does NOT make ozone more abundant than nitrogen and oxygen.
The Stratosphere has 2 parts, the normal Stratosphere and the Ozone layer. The Thermosphere also has 2 parts. They are the Thermosphere and Ionosphere.
There is no connection between the two issues. The thinning of the ozone layer that we see over each pole during their winters is an event caused by CFCs and other halogen gases releasing chlorine and bromine, as well as a lack of sun hitting that layer. Once the daylight returns, the hole gradually fills up.
The ozone is founded in atmosphere at ozone layer. It is founded at ground level as pollutant.
Ozone can be found in the Earth's stratosphere, where it forms the ozone layer. It can also be found at ground level, often as a result of pollution, in urban areas where it is a main component of smog.
