The ozone depletion is actually something happening naturally. It is an ongoing process. The moment ozone was formed, its formation and depletion were the phenomenons that run parallel to each other.
However the rate of formation of ozone was same as its depletion so no frequent changes were seen in its thickness or concentration. However the water vapour was still present at that time which could deplete ozone but the factors like the CFC's or other ODS i.e. ozone depleting substances were not present at that time.
The ozone depletion and ozone formation are actually the phenomenon which were or are carried by the same high energy ultraviolet radiations. These ultraviolet radiations make the oxygen molecules present in the lower stratospheric region of the atmosphere dissociate onto two single atoms of nascent oxygen i.e. [O]. These nascent oxygen atoms individually react with the oxygen molecules to form ozone molecule. However the same Ultraviolet radiations make the ozone molecule break down into oxygen molecules. However with the start of the industrial revolution and the discovery of the CFC's the rate of depletion of ozone increased as compared to the formation rate and thus a so called ozone hole was formed in the ozone layer of the earth.
Ozone layer contains ozone in it. Therefore, it is named so.
Earth has a layer of ozone. It is present as the ozone layer.
Earth and Venus have a protective ozone layer. These planets have ozone molecules in ozone layer.
There are no layers in the ozone layer. It is a single layer of pool of ozone gas.
Stratosphere contains the ozone layer. It is a pool of ozone molecules.
If the ozone layer keeps on taken for granted, then it will deplete. The depletion has already began.
Ozone layer contains ozone in it. Therefore, it is named so.
ozone layer in Tagalog: ozone layer (no direct Tagalog translation)
Ozone layer is formed of ozone. It is a gas.
Earth has a layer of ozone. It is present as the ozone layer.
damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
The layer of gases that surround the atmosphere is ozone. It is present as the ozone layer.
Ozone layer is the layer of ozone. Humans are altering it by CFC's.
The ozone layer is in the stratosphere. It is a pool of ozone molecules.
Earth and Venus have a protective ozone layer. These planets have ozone molecules in ozone layer.
In the ozone layer. Where the ozone is.
The stratosphere has ozone in it. It is present as ozone layer.
