Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

With sufficient humidity in the cooler layer, fog is typically present below the inversion cap. An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky.
Another way fog forms in deserts occurs when a desert is close to an ocean which has a cold current. When air is heated over desert land and blows towards the cool water in the ocean, it condenses and fog is formed. The cool fog is then blown inland by the ocean breeze. Fog is mainly formed in the early morning or after sunset. [5]
You may have woken up to steamy windows or noticed fog hanging over downtown Kansas City in the morning. This is caused by the air temperature lowering just enough overnight to meet the high dew ...
Earth Day is on April 22 because of college schedules. The date for Earth Day was largely dictated by the schedules of the college students Hayes and Nelson were hoping to attract. April 22 fell ...
Looming of the Canadian coast as seen from Rochester, New York, on April 16, 1871. Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
According to the U.S. Department of State, roughly 8 million metric tons of plastic go into the world's oceans every single year.Given that most plastics aren't biodegradable, they are likely to ...
