CFCs, nitrous oxide.
CFC's react with ozone. They deplete the ozone layer.
Ozone layer is being depleted. The chemical reactions involve depleting of ozone into oxygen.
Ozone layer has undergone various changes. These are the depletion of ozone molecules.
Ozone is a very important gas and chemical for it. In the ozone layer, it acts as the protective layer of the earth.
The ozone layer is a layer of ozone gas. The layer is present in stratosphere. It helps in protecting earth.
Chlorofluorocarbons damage the protective ozone layer.
CFC is destroying ozone. It is the industrial chemical.
Chemical
The chemical that cause ozone hole over antarctica is CFC. Chlorofluorocarbons are the ones that contain chlorine which deplete ozone layer.
CFC's destroy ozone. They react with ozone to deplete it.
To prevent holes in ozone layer, we have to prevent the use of CFC chemical in our environment.
The production and decay of ozone are chemical processes.
