Humans need oxygen to breathe. Plants produce oxygen. How do places (like a desert) with no plants for miles on miles have any life or oxygen?

Question

Title says it all. Just curious as to how there is anything living if there is no plants to give off oxygen. Does other stuff give off oxygen? Is there just enough on the planet in general for it to flow everywhere?

Answer 1

Because the (solid part of the) planet rotates, and because the Sun warms up different areas as they are exposed to sunlight, you end up with a lot of wind moving the atmosphere around. [Prevailing Winds](https://en.wikipedia.org/wiki/Prevailing_winds) is what they’re called, and as you can see the air is “thoroughly circulated” pretty much everywhere.
