pollution
CFC's get trapped. They react with ozone to deplete it.
The layer of gases that surround the atmosphere is ozone. It is present as the ozone layer.
Ozone gets trapped in the ozone layer. It protects us from harmful UV rays of the sun.
The ozone gases are being destroyed by CFC's. They react with ozone to deplete it.
There are not two gases in the layer but one. Ozone is the only gas present in the ozone layer.
Ozone layer is getting depleted due to release of CFC gases. CFC gases react with ozone and break it into oxygen. So, holes in ozone layer are places where ozone is broken into oxygen.
The gases that destroy ozone are CFC's. They react with ozone to deplete it.
Very little connection between the ozone layer and greenhouse gases.
There are no multiple gases. There is only one and that is ozone gas.
The ozone at ground level is a pollutant. It is trapped by other greenhouse gases.
The ozone layer is depleted by man made CFC gases. They react with ozone.
The loss of ozone layer is the loss of ozone molecules. It is due to the CFC gases released.
