An ozone hole is formed when the amount of ozone in the upper atmosphere gets depleted to dangerously low levels. Normally, Chlorofluorocarbons, or CFC's, are responsible for this. In sunlight, CFC's form chlorine radicals which react with Ozone to produce Oxygen gas. If XCl is a CFC, the steps in which reactions proceed are:
In sunlight in the upper atmosphere: XCl ------> X + Cl
Cl is the chlorine radical, which is extremely reactive.
Cl + O3 -----> O2 + ClO
ClO is another radical, which is also extremely reactive.
ClO + O3 -----> Cl + 2O2
As you can see, the Chlorine radical, Cl, is produced again at the last step, allowing it to repeat the steps again and again. In fact, it is estimated that each Chlorine atom can react with up to 200,000 ozone molecules, before decaying.

What is the number of atoms in ozone?
Three oxygen atoms combine to make ozone
What effect do scientists predict banning the use of CFC will have?
Keep the ozone layer intact. CFC's in the upper atmosphere destroys the Ozone layer and puts a hole in it, allowing more UV radiation in.
How many molecules of ozone can you make from 6 atoms of oxygen?
Ozone molecule has 3 atoms of oxygen and its Symbol is O3.
Why is the ozone deteriorating?
The ozone layer is diminishing because of the excessive use of ozone depleting substances by the humans. These ODS contain chemicals which react with the ozone in the ozone layer and deplete it.
What gas molecule found in Earths atmosphere is made up of three oxygen atoms?
You are thinking of ozone.
How does the hole in the ozone layer make the poliution worse?
The ozone hole leads to global warming. This then leads to worse pollution.
What is the name of the hole in the ozone?
The name of the hole is ozone hole. It is the thinning of ozone layer.
How do you be careful not to have a big hole the ozone layer?
We have to be cautious not to have a big ozone hole. It is because it will make UV radiation enter the earth.
How do you plan to fix the ozone hole?
We can each make individual efforts to reduce the ozone hole. It can be done by stopping the use of CFC's.
What is the meaning of a hole in the ozone layer?
See "What is the ozone hole?" in the "Related questions" section below.
Could the nuclear bomb caused a hole in the ozone layer?
Yes, it could. The gases released could make a hole in ozone layer.
Why is there a ozone hole?
Ozone hole is the thinning of ozone layer. It is due to ODS.
What is the term ozone hole?
a hole in the ozone layer.
How big was the ozone before it got its hole?
In the fall and spring, ozone covers the entire planet. When it is winter at one of the poles, an ozone hole forms since there is no UV-C from the Sun to make more ozone.
Where was an “ozone hole” discovered in the 1980s?
The ozone hole was discovered over Antarctica.
How they descoverd ozone hole?
Ozone hole was discovered by Joseph Farman. He discovered the ozone hole over Antarctica.
How useful was the Antarctic ozone hole?
The Antarctic ozone hole is not useful. It was harmful.
