Asked by Leo

What is in our ozone layer that stops our sun's mega high radiation from entering our atmosphere?

The Ozone layer is made of gaseous molecules of O3, unlike O2 which we breathe in. The bonds in O3 are able to absorb the UV radiation to form O2 and O. This also allows for the ozone to be regenerated constantly to form O3 again. The actual name of the process is called ‘Free Radical Substitution’. You may have heard that the Ozone is being depleted from the atmosphere. This is due to certain chemicals and pollutants being used extensively, these prevent the Ozone from being regenerated, leading to a reduce amount of Ozone in the atmosphere. Hope this helps :)

It it is gas Ozone (O3) that helps to regulate the earth’s temperature. It absorbs UV radiation and IR radiation at different levels of our atmosphere.
