Different kinds of Fog and How it is created

     

     Fog is a cloud that forms just above the ground. There are two kinds of fog Advection fog and "radiation," or ground fog. Advection fog is common on the pacific coast of the United States. The Advection fog forms when moist airs over the Pacific Ocean are blow inward. When that air moves over coastal waters, it cools quickly and fog forms. The other kind of fog is common in lots of places. It forms when a layer of warm, moist air forms to the ground. A layer of cooler, dry air forms over top. As the ground cools, the warm, moist air is cooled quickly. As the air temperature lowers, small droplets of water condense, which we see as fog . Radiation fog forms most often on cool, clear nights with a very slight breeze. It forms first in low valleys and spreads outward so long as condition’s remain the same
