Water vapor can indeed move through several processes in addition to air transportation. One of the ways is through diffusion, specifically diffusion through materials. This process involves the movement of water vapor from areas of higher concentration to areas of lower concentration through permeable materials such as walls or membranes. Thermal diffusion is another mechanism through which water vapor can move. This phenomenon relates to the effect of temperature gradients on the movement of water vapor, where warmer areas tend to allow for more vigorous movement of water molecules.

Combining these two processes, diffusion through materials facilitates the passage of water vapor as it seeks equilibrium, while thermal diffusion contributes by allowing temperature differences to drive the movement of molecules, impacting their kinetic energy and hence altering their distribution in a given space. Together, these mechanisms complement air transportation, which involves the larger-scale movement of water vapor through the air.

In contrast, options like condensation and evaporation focus more on phase changes than on the transport mechanisms of water vapor itself. Therefore, while both are key processes in the water cycle, they do not align with the question about how water vapor moves. Similarly, conduction and insulation are related to heat transfer and do not directly pertain to the movement of water vapor.
