ELI5: Why is the ozone layer higher up than oxygen gas? Should not ozone(O3) weigh more than oxygen gas(O2) and therefore closer to the earth?

Ozone is found lower down in the atmosphere as well. You can even smell it. It is what produces the smell of lightning or other electric sparks. However ozone is very reactive and will quickly react with other elements. So even though ozone is heavier then oxygen you will usually not find it far from where it is being created. The reason there is a layer of ozone in the upper atmosphere is because oxygen will react with ultraviolet light to create ozone. And the upper atmosphere gets a lot of ultraviolet light from the Sun.
