Fog and cloud are essentially synonymous, except that fog exists at ground level, and clouds exist above the ground. There are actually several different types of fog, radiation fog (due to cooling of moist air at night), steam fog (due to cold air moving over warm, moist surface like a lake), advection fog (due to saturation of surface air as moist air is brought into the area by the wind), etc. All fogs are ground-based.
Hope this helps. For more information on all weather hazards, and how to use the Internet to anticipate their occurrence, I have developed a public education course about it. For more information, go to http://www.storm-prep.com.

Cloud at ground level is called fog.Fog generally forms when the wind is calm.But clouds are formed even when there is wind.Stratus cloud is an example.It sometimes forms near the ground and moves very fast with the wind.
