How clouds are formed

The cloud formations of interest to the mariner are formed in the Troposphere. The Troposphere is a layer of the earth’s atmosphere that extends from the earth’s surface to about 24.000 feet (7.300 meters) above the poles, and to about 65.000 feet ( 19.800 meters) above the equator. Clouds in the Troposphere are made up of water droplets or ice crystals, and can occasionally be a combination of both. The consistency of clouds always depends on the temperature.
