Answer-Fog is an example of –

Fog is a collection of liquid water droplets or ice crystals suspended in the air at or near the Earths surface. While fog is a type of stratus cloud, the term fog is typically distinguished from the more generic term cloud in that fog is low-lying, and the moisture in the fog is often generated locally such as from a nearby body of water, like a lake or the ocean, or from nearby moist ground or marshes. Fog is distinguished from mist only by its density, as expressed in the resulting decrease in visibility.
