Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganismsâyeasts or bacteriaâunder anaerobic conditions. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy.
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated âthat is, become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth.
Animation by: Bramer. Precipitation is the primary mechanism for transporting water from the atmosphere to the surface of the earth. There are several forms of precipitation, the most common of which for the United States is rain. Other forms of precipitation include; hail, snow, sleet, and freezing rain. A well developed extra-tropical cyclone could be responsible for the generation of any or all of these forms of precipitation.
