Answer:
Fog forms when the difference between air temperature and dew point is less than 2.5 °C (4.5 °F). Fog begins to form when water vapor condenses into tiny water droplets that are suspended in the air. ... This occurs from either added moisture in the air, or falling ambient air temperature.

how does the fog comes?
- Fog actually forms close to the Earth where we see it. The same scientific processes that usually happen way up high in the atmosphere to create clouds can take place closer to the ground. When they do, we get fog.
- Basically, fog forms when warm air meets colder air. When this happens, water vapor in the air — a gas — is cooled enough for the gas to turn to a liquid in the form of tiny water droplets. This process is called "condensation."
- We see those groups of tiny droplets as clouds or, when they're close to the ground, as fog. As the air heats up again, fog will slowly disappear as the tiny water droplets once again return to a gas in the form of water vapor.
