The layer is heated.
Some oxygen, nitrogen, and ozone molecules are destroyed.
Ozone is made.
This is how the ozone layer returns after the polar winters deplete the layer. Lack of sunlight is the major issue with ozone depletion and the ONLY method that allows the ozone to return.

What causes black hole in the Ozone Layer?
there is no black hole, but a thinning of the ozone levels over the Antarctic every winter. This has been happening for centuries due to a lack of sunlight hitting the oxygen in the area. Because ozone decays so quickly, sunlight must hit oxygen to create more ozone or the thinning occurs. The hole disappears once sunlight hits the area.
What happens when a meteor hits the ozone layer?
It comes right on through.
How does iron oxide harm the environment?
Because the oxide hits the ozone layer and I think that is why
What is ozone layer in french?
"couche d'ozone" seems to have about 344,000 hits on French language websites.
How does the depletion of ozone layer by man happen?
Chlorofluorocarbons (CFC's) used in air conditioning systems and fridges leak out and rise into the stratosphere. Here they destroy the ozone layer. UV light from the Sun has the power to break the bonds of the O2 molecule making O3. This ozone hole is huge and allows short wavelength UV from the Sun to reach the ground and lasts for up to three months. The hole only occurs during the end of the winter in the Antarctic and is due to a lack of sunlight. The hole lasts above the Antarctic until the sun returns each summer. No thinning is observed near the equator as sun hits this area consistently.
How can CFC's damage the ozone layer?
the cfc's effect the ozone layer by breaking the bond of the atoms in the ozone layer.so it pulls apart the atoms and breaks the bond and the harmful radiation comes through and hits the earth
How do pollutants destroy the ozone layer?
Water vapor, molecules containing chlorine and/or bromine, and not-fully-oxidized molecules containing carbon or sulfur.Horse manure:One gas that causes the destruction of the ozone layer is lexineflouride or leF. Lexineflouride hits the UV rays and basically causes different chemicals to react between the UV rays and leF causing skin cancer and other diseases to occur.
What happen to the ozone layer if it was damaged?
Ozone layer is essential for the survival of life on earth. It blocks 97% of the radiation received by the earth. If it is damaged, temperature rise of atmosphere will burn the humans on earth. And the harmful radiations will kill the rest.
How does ozone layer protect us from UV rays?
Nitrogen and Oxygen stop UV-C and more energetic radiation. When they do this, they are broken down into constituent atoms. N2 + energetic light -> 2N O2 + energetic light -> 2O Some of the oxygen forms ozone (eventually). Ozone is broken apart by absorbing UV-B and more energetic radiation. O3 + energetic light -> O2 + O
What effect does the depletion of ozone have on animals and plants?
Ozone, O3, is a gas in the upper atmosphere that absorbs UV light. This means less UV light gets to the Earth. UV light causes humans to synthesise Vitamin D, needed for healthy bones and teeth. However, it also causes skin damage- the reason why we tan/burn in sunlight. Less O3 means more intense UV light- known to increase skin cancer and cataract rates in areas where this has happened. With plants, I don't think it has a great effect- they just use pockets of sunlight energy for photosynthesis.
Where is the ozone most polluted?
Most of the ozone is present in the stratosphere as the ozone layer. Ozone is also present in troposphere and at ground levels but the concentration is of the level of parts per million(ppm) so it can be considered as negligible as compared to one present in the lower stratosphere.
Is radiation from Solar energy bad?
Ultra violet radiation is bad, but once it goes through the ozone layer in the stratosphere is it harmless if a little hits you.
