There is only one gas. Ozone which is a type oxygen.
The layer of gases that surround the atmosphere is ozone. It is present as the ozone layer.
There are not two gases in the layer but one. Ozone is the only gas present in the ozone layer.
The gases that destroy ozone are CFC's. They react with ozone to deplete it.
There are no multiple gases. There is only one and that is ozone gas.
The loss of ozone layer is the loss of ozone molecules. It is due to the CFC gases released.
The ozone layer is depleted by man made CFC gases. They react with ozone.
Gases are many that can contribute to ozone. Greenhouse gases to be mentioned here.
The ozone layer contains the most molecules. They are present as ozone layer.
Ozone layer is a layer having only one layer of gas. That layer of gas is ozone layer.
CFC's are the gases that react with ozone to break it down. They deplete the ozone.
Ozone layer is destroyed by the CFC gases released. It is also depleted because of industrial released gases.
There is only one component to the ozone layer. It is the ozone gas itself i.e. a pool of gases.
