The size has decreased. The ozone has started to replenish itself.
It has decreased. Because countries have placed ban of CFC's.
The size of ozone hole is changing. It can either be increased or decreased.
Yes,the size of the ozone hole has increased in size by 36%. The hole was around the size of Cuba in 1979 (130,000 sq km) and has grown to the size of North America today (25 million sq km).
If oxygen decreased, ozone will decrease. It is because ozone is made from oxygen.
We can help in stopping ozone depletion. We can do that by stopping use of CFC's as ODS.
Good ozone is ozone that is between the DNA-based life on/near Earth's surface and the Sun. Ozone absorbs the UV-B from our Sun, that would otherwise cause increased cataracts, cancer, mutation, decreased crop yields, and increase loss of arable land.
Ozone production occours in stratosphere. It is present as ozone layer.
Ozone depletion is prevented by stopping CFC use. They are the ones that deplete ozone.
Yes, it can be said. The production of hydroxide ions is contributing to ozone.
Increased ground level ozone can cause problems. It is a pollutant.
Ozone is formed in part by nitrogen gas briefly holding on to a singlet oxygen, which later drops onto an oxygen molecule (usually involving low energy visible light). NOx can be converted to essentially nitric acid by the presence of water vapor. Addtionally, ozone is decayed by water vapor via the peroxide mechanism. So, "depression" is a reduction of ozone both by increased decay and decreased production. "Acidification" is conversion of NOx to some more stable versions that are unable to form ozone, but have the energy to stay as an acid.
Ozone gas is a tri atomic gas. It is present as the ozone layer and it affects plant production.
