Ozone
Definition
Ozone is an allotrope of oxygen consisting three oxygen atoms bonded together into an O3 molecule. It forms naturally in Earth's upper atmosphere where it protects life from harmful ultraviolet radiation from Sun.
Analogy
You can think of ozone as Earth's sunglasses. Just like how sunglasses protect your eyes from harmful UV rays, the ozone layer absorbs most of these rays before they reach the surface.
