How Fog is Formed? - Chemistry Shaalaa.com
Sea fog (also known as haar or fret) is heavily influenced by the presence of sea spray and microscopic airborne salt crystals. Clouds of all types require minute hygroscopic particles upon which water vapor can condense. Over the ocean surface, the most common particles are salt from salt spray produced by breaking waves. Except in areas of storminess, the most common areas of breaking waves are located near coastlines, hence the greatest densities of airborne s… WebBut the fog is not always dangerous or harmful. Some countries also use the fog to obtain drinking water for the population. They use a grid with very small holes to filter the water … WebInitially it may be mist that forms and then thickens into fog as the temperature drops and more water vapour condenses into water droplets in the air. Air does not conduct heat very well so in still air conditions fog may not form at all and a layer of dew or frost will form on the surface instead. diamond cut mens chains
