Answer to Question #21681 in Inorganic Chemistry for bilal
how fog forms?
Fog begins to form when water vapor condenses into tiny liquid water droplets in the air. The main ways water vapor is added to the air: wind convergence into areas of upward motion, precipitation or virga falling from above, daytime heating evaporating water from the surface of oceans, water bodies or wet land,transpiration from plants, cool or dry air moving over warmer water, and lifting air over mountains.Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds.Fog, like its slightly elevated cousin stratus, is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass.
