There are various facts about ozone hole. The main being that it is caused by CFC's.
Ozone layer is present in stratosphere. It is a pool of ozone molecules.
Ozone is a triatomic gas. It is an allotrope of oxygen.
Ozone has many false facts. One of it is that it is a compound.
Ozone is a triatomic form of oxygen molecule. It is a pollutant at ground level.
Ozone layer is created and depleted both by UV. A CFC molecule can destroy up to 100,000 molecules of ozone.
There are various interesting facts about ozone. One is that UV is the thing that forms and depletes ozone both.
Ozone layer is present at 10-50 km in the atmosphere. It can easily stop the UV-C radiations.
It has the ozone layer It starts at 12 km ends at 50 km of sea level
You have your facts wrong. Ozone boils at -111.9°C. It is warmer than that in the ozone layer. Note that water is sometimes a gas at low temperature, even though it boils at 100°C. Clouds, rain, "humidity".
Ozone is a molecule made up of three oxygen atoms and is found in Earth's stratosphere, where it forms the ozone layer that helps protect us from harmful UV radiation. Chlorofluorocarbons (CFCs) are a group of man-made chemicals that were once commonly used in refrigerants, aerosol propellants, and solvents. CFCs are harmful because they break down ozone molecules in the stratosphere, contributing to ozone depletion.
Earth's atmospheric layer contains ozone layer. It protects us from harmful UV radiations of the sun.
