Why is there sand in deserts and no dirt? Why isn’t there sand anywhere else?

Question

I figured it was something to do with sand being light enough to be carried by wind, but that wouldn’t explain why the rest of the world lacks sand.

Answer 1

Deserts can be sand, clay, and probably some other things. The dirt you’re thinking of is the same but with a lot of dead stuff in it like leaves, grass, etc. That stuff just doesn’t grow enough in the desert to make dirt. So the sand is in a lot of places all over the world. It just looks like the dirt you’re talking about.
