Fog. What is fog? How does it accur? Do you have a cool exsperence with fog. If you do then tell me.

 Fog is a cloud which is at ground level.  Fog forms when the air can no longer hold moisture in the form of vapor.  This concludes to water precipitates out of the air,  a fine mist of water droplets. If the air becomes saturated enough, which the droplets will turn into drizzle or rain. In the past we had two hour delays which gave everyone some more sleep and made me not in a bad mood, since I am not a morning person.
