Dew forms as the temperature drops to the dew point. Water droplets love to collect on surfaces or tiny particles. It is very difficult for water drop.

Fog: A suspension of small visible water droplets (or ice crystals) in the air that reduce visibility at the earth's to less than 1,000 meters (5/8 miles).

Radiation Fog or Valley Fog

Advection Fog

Up Slope Fog

Other Types of fogs: * acid fog -- radiation fog that forms in polluted air with oxides of sulfur and nitrogen. * evaporation (mixing) fog -- mixing of two unsaturated air masses (steam fog, winter breath, arctic sea smoke, steamy pavement). * frontal fog -- a type of evaporation fog; moist air mixes with cooler air; can occur where warm air rides up over cold air (warm front).
