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.
A model of ozone could be made in a plastic layer. Smoke can be used for realistic effect.
Draw a poster or cut a section ofa styrafome ball and paint the sections of the ball to match the layers of the earth
Three oxygen atoms combine to make ozone
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.
Ozone molecule has 3 atoms of oxygen and its Symbol is O3.
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.
You are thinking of ozone.
The ozone hole leads to global warming. This then leads to worse pollution.
The name of the hole is ozone hole. It is the thinning of 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.
We can each make individual efforts to reduce the ozone hole. It can be done by stopping the use of CFC's.
See "What is the ozone hole?" in the "Related questions" section below.
Yes, it could. The gases released could make a hole in ozone layer.
Ozone hole is the thinning of ozone layer. It is due to ODS.
a hole in the ozone layer.
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.
The ozone hole was discovered over Antarctica.
Ozone hole was discovered by Joseph Farman. He discovered the ozone hole over Antarctica.
The Antarctic ozone hole is not useful. It was harmful.
