Which mechanism describes moisture movement via air flow as water vapor?

Explanation:
Moisture moves as water vapor when it is carried by the moving air itself. This bulk transport of vapor with the air flow is advective moisture transfer, meaning the air’s movement carries the vapor from one place to another. It’s different from diffusion, which is a slow, random spreading of vapor due to concentration differences without any bulk air movement. It’s also not gravity, which acts on liquids, nor capillary action, which moves liquids through tiny pores by capillary forces. So the mechanism described by moisture movement via air flow as water vapor is the bulk transport of vapor by moving air.
