What is fog?
Fog, similar to a cloud, is a condensed compression of little water droplets which is located towards the surface/ground of the earth.
State of Water: Gas/Water Vapor
What causes Fog?
Fog is caused, when the dew point of the area, is less than 4 degrees Fahrenheit (2.5 degrees Celsius). The condensation of the water droplets, causes the fog to form. Sudden formation is called “Flash Flood.” The fog originates in conditions of 100% humidity.
The effects of Fog?
The occurrence of fog leads to numerous effects. To start the visibility of the certain area can decrease to a low amount, somewhat around 1 kilometer (0.62 miles). Fog involves mist, and a lot of humidity in the air, and a large presence of water. However, though similar to mist, it is different through their densities. Fog also can cause various forms of participation such as light rain or light snow.
These effects cause a few problems. An example is the visibility. When one is driving a car, or even walking down a street, the fog can totally reduce the visibility making it dangerous for the car drivers and even pedestrians, as it poses a risk for them to get hit or even hit another person. To solve, this cars are fitted with headlights, which can be used as an fog light. Pedestrians can wear bright and even reflective clothing to be more noticeable on the street.
The different types of Fog?
There are a few different types of fog. They include; radiation fog, advection fog, valley fog, and freezing fog
Radiation: Commonly known as ground fog, radiation fog generally appears in the evening. It occurs when the heat soaked in by the earth, is released into the air and causes water droplets, allowing fog to be produced.
Advection: When humid, warm air makes contact with a cool surface, this causes the condensation of the water droplets resulting in the formation of fog .
Valley: This type of fog occurs when the mountains prevent the dense air from escaping, which eventually involves the condensation of the water vapor. This generally happens in the winter time.
Freezing: Generally occurring in areas of extreme cold like Antarctica, this fog type happens when the water droplets and condensation freezes, which causes fog to appear.
