You get free gifts, we make world greener

Hello GreenZoners,

Today we have for you two words connected with ecology and environment in one post.

First one is a name of molecule, second one is a name of a layer. Do you already know our words?

Yes, ozone and ozone layer.

Ozone is a triatomic molecule, consisting of three oxygen atoms. It is present in low concentrations throughout the Earth’s atmosphere. Layer in atmosphere which absorbs most of UV radiation of the Sun and contains relatively high concentrations of ozone is called ozone layer.

Ok, so we have an ozone and an ozone layer. There should be third word connected with this topic. Any ideas?
