Fog is often described as a stratus cloud resting near the ground. Fog forms when the temperature and dew point of the air approach the same value (i. e, dew-point spread is less than 5°F) either through cooling of the air (producing advection, radiation, or upslope fog) or by adding enough moisture to raise the dew point (producing steam or frontal fog). When composed of ice crystals, it is called ice fog.
Which describes where fog forms?
Brush teeth twice a day., and floss daily. Brush or scrape your tongue. Use a mouth rinse. Visit your dentist. Quit smoking and avoid tobacco products. Wet your whistle. Eat a piece of sugarless candy or chew sugarless gum.
Another thing we wondered was when fog is formed?
Fog appears when water vapor (water in its gaseous form) condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. Sea fog, which shows up near bodies of saline water, is formed as water vapor condenses on bits of salt.

In summary, fog is condensed water vapor that normally occurs close to the ground. Fog happens when warmer air interacts with cold air. The cold air can hold less water vapor than the warm air, so the water vapor condenses into liquid water to form fog.
You could be asking “When are you most likely to encounter fog?”
Let us dig a little deeper. fog forms often near creeks, waterways and river valleys as the water increases the humidity in the air. Fog is most likely to occur when the dewpoint level is very near the current temperature reading, being no more than 5 degrees F., and difference.
Fog cover tends to dissipate as the sun gets stronger at around midday since fog is primarily composed of moisture suspended low above the atmosphere. The heat from the sun causes the water droplets to evaporate, and this is why fog is usually seen early in the morning or late in the evening.
What should you do when fog becomes very dense?
, and slow down! Use low-beam head lights and fog lights for best visibility. Turn on your four-way flashers. Watch out for vehicles on the side of the roadway. Use roadside highway reflectors as guides to determine how the road may curve ahead of you. Use wipers and defroster as necessary to maximize visibility.
Where does the word fog originate come from?
Fog (n.2) “long grass, second growth of grass after mowing,” late 14c, probably of Scandinavian origin; compare Norwegian fogg “long grass in a moist hollow,” Icelandic fuki “rotten sea grass. ” A connection to fog (n.1) via a notion of long grass growing in moist dells of northern Europe is tempting but not proven. Watkins suggests derivation from PIE *pu-(2) “to rot, decay” (see foul (adj.)).
