eli5: Why do deserts and places with little to no vegetation have as much oxygen as everywhere else.

Question

Is there simply so much oxygen that it gets everywhere on Earth or is it something else?

In: Physics

Answer 1

Maybe there *isn’t* as much oxygen in these places. We’d need to measure it to be sure. Maybe there is just enough to make it somewhat habitable. Also, these places aren’t typically densely populated, so maybe less oxygen lasts longer in these places.
