Fog is technically a type of stratus cloud, which lies along the ground and obscures visibility.

It is usually created when humidity in the air condenses into tiny water droplets. Because of this, some places are more prone to foggy weather, such as regions close to a body of water.

Fog is similar to mist; both are the appearance of water droplets suspended in the air, but fog is the term applied to the condition when visibility is less than 1 km.

Next Topic: Graupel

Freezing rain is a condition where precipitation which has fallen in the form of water droplets reaches temperatures which are below freezing and freezes upon coming into contact with surface objects. The result of this precipitation is a glaze of ice which can be damaging to plants and man-made structures. A severe onset of freezing rain which results in a very thick glaze of ice is known as an ice storm.
