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

The entire premise of your question is wrong. Deserts have all types of soil in them. Have you ever seen a playa? That is clay and silt. Also, sand is found in many places. The topsoil of the upper Midwest of the US is mostly sand. River beds are made of sand.
