Which one is more correct, "earth's air" or "earth' air"?

[Anuradha Chepur]

We usually say 'atmosphere' instead of 'air'.
When talking about possession of inanimate nouns, we use
the preposition 'of', instead of 's.
The "atmosphere of the earth," is what I would prefer.

But if you want me to choose one of the options you gave,
then it is 'earth's air.'

Thank you, sir.
