hapter 7 Questions Clouds to form in the atmosphere have to have water vapor present. This water vapor makes up a cloud. The water vapor in the atmosphere comes from evaporation or deposition. Also the temperature of the air is below the dew point. When the water is fully saturated, it starts to rise and the expansional cooling process begins. During the process of condensation, the aerosol particles act like a nuclei in the atmosphere, which began to grow, creating ice crystals that are big enough to produce a cloud. Examples of natural sources of nuclei could be wind erosion of soil, volcanic eruptions, sea spray, ocean organic compounds and even forest fires. Cloud condensation nuclei (CCN) helps assist the condensation of the water vapor process. When the process of condensation occurs, the nuclei which are particles of liquid that are found in the atmosphere, helps water vapor grow and condense turning into a cloud formation. Hygroscopic nuclei is derived from the cloud condensation nuclei process. It is very significant in cloud formation because it can pull together different types of water molecules in the atmosphere due to a …show more content…

The usually have a temperature of -13 degrees Fahrenheit (-25 degree Celsius) therefore ice crystals is what mostly makes up this type of cloud, which has a fibrous appearance. For middle clouds, they have altitudes between (6,600-16,000 ft) and a temperature range from 32 degrees Fahrenheit (0 degree Celsius) and -13 degrees Fahrenheit (-25 degree Celsius). These clouds can either have supercooled water molecules or they have a combination of both water droplets that are supercooled and ice crystals. For low clouds, can have an altitude up to (6,600 ft) and have a temperature of 23 degrees Fahrenheit (-5 degrees Celsius). They can appear as fog or stratocumulus clouds. Water droplets mainly make up these low clouds and
