Why do things burn when passing through earth's ozone layer?

Answer 1

The Sun emits a broad spectrum of light including UV-C and UV-B. When UV-C is absorbed by an oxygen molecule, sometimes ozone is formed. When UV-B or UV-C is absorbed by ozone it breaks apart, and sometimes ozone is formed again. So "burning through" ozone also produces some ozone. The amount of ozone at any given time is a delicate balance between incident sunlight, ozone left over from the previous day (ozone decays with time too), the amount of oxygen available, and the various decay paths presented by contaminants. As contaminants increase, or new decay pathways are presented, ozone concentration decreases. Not only will the sun not burn through the ozone layer, the sun is required to create new ozone. The thin layer we misrepresent as a hole is due primarily because the sun can not react with the atmosphere and the ozone naturally decays.

Answer 2

I will assume you meant "What doesn't [make] the ozone layer disappear?" Anything that makes oxygen, and / or removes moisture from the air helps the ozone layer. That would be most plants. Please see the links below if you meant something else.

Answer 3

It serves as an effective barrier against the sun's ultraviolet (UV) rays. UV light is outside the spectrum of visible light, but it's very harmful. In the absence of ozone's protective shield, life as we know it on Earth would be extinct

Answer 4

Things burn not due to the ozone layer but due to friction. Earth's atmosphere allows large friction to burn them up.

Answer 5

Sun's rays penetrate the ozone layer. It is when there is ozone depletion.
