Eventually, where does all the dust in the world go?

Question

Does it just get re-circulated? You clean your place and make your neighbour’s place dirty, and vice versa?

Answer 1

It eventually settles on a surface. It tends to stick to other dust, aggregating into dirt and grime. Rain speeds the process substantially. Dust is much more persistent in deserts. Some dust goes into the waterways, some on the ground. It settles on lake bottoms and vegetation and, over eons, becomes sedimentary rock.
