उत्तर
Wind movement
Explanation:
The pre-conditions for condensation to occur are: the air must be saturated with water vapor, the temperature must reach or fall below the dew point, and there must be tiny particles like dust or smoke in the air (called condensation nuclei) around which water vapor can condense. Wind movement is not a necessary condition for condensation; it may influence air movement, but it is not essential for condensation to happen.
