I have a question about the ozone layer.

The ozone layer is a layer of gas in the upper atmosphere that protects us from harmful ultraviolet radiation from the sun. It is made up of three main components: Ozone, nitrogen dioxide, and carbon dioxide. Ozone is a molecule composed of three oxygen atoms, while nitrogen dioxide is a molecule composed of two nitrogen atoms and one oxygen atom. Carbon dioxide is a molecule composed of two oxygen atoms and one carbon atom.
