Eli5 is there an altitude where wind stops?

Question

I understand there is no wind in space, and that air gets thinner the higher up you go, but is there a point in height from the surface, before space, where there is no more wind?

Nope!

Wind is the movement of air, driven by local changes in air pressure, mostly caused by uneven heating of the air. Anyway, while this is incredibly complex, and there are different heights in the altitude where winds tend to be faster or slower, wind in some form or another continues basically until there’s no air left. Even above the 100km mark that is often used to demarcate “space”, there are measurable mass movements of what gas molecules there are – or, in other words, wind!
