There is a gradula thinning of the ozone in the atmosphere because of the ozone depleting substances. These substances contain CFC's which deplete the ozone by reacting with it.
CFC's cause thinning of ozone. They react with ozone to deplete it.
Thinning of ozone can be reversed by reducion of CFC's. If CFC's are reduced, there will be no more thinning.
The weakening of ozone layer is due to its thinning. The ozone is thinning because of the attack of ozone depleting substances on it.
The thinning of ozone layer. When this thinning reaches a certain concentration then it is ozone hole.
It can be reversed but not quickly. Ozone thinning will be reversed gradually and slowly.
CFC's cause thinning of ozone. They react with ozone to deplete it.
CFC's are responsible for thinning of ozone. They react with ozone to thin it.
Thinning of ozone can be reversed by reducion of CFC's. If CFC's are reduced, there will be no more thinning.
The ozone layer shields the planet surface from harmful radiation from the sun. The less the ozone layer, the more the risk of skin cancer.
The thinning of ozone layer is the depletion of certain amount of molecules of ozone in the ozone layer. This is a harmful phenomenon.
The weakening of ozone layer is due to its thinning. The ozone is thinning because of the attack of ozone depleting substances on it.
The thinning of ozone layer. When this thinning reaches a certain concentration then it is ozone hole.
The reduction in concentration of ozone molecules is the thinning. It is caused by CFC's.
CFC's are causing its thinning. They react with ozone to deplete it.
It can be reversed but not quickly. Ozone thinning will be reversed gradually and slowly.
The thinning of ozone layer is mainly due to man made ozone depleting substances. They react with ozone and decompose it.
The thinning of ozone overall is called ozone depletion. It can be due to a number of factors.
