Sublimation | solid changes directly into a gas |
Dew Point | The temperature at which the condensation rate equals the evaporation rate |
Cloud | a collection of small water droplets or ice crystals in the air |
Condensation Nucleus | The suspended particles that provide the surfaces necessary for water vapor to condense |
Adiabitic cooling | The process by which the temperature of a mass of air decreases as the air rises and expands |
Advective Cooling | Another cooling process that is associated with cloud formation |
Stratus Cloud | Clouds that have a flat, uniform base and that begin to form at very low altitudes are called |
Cumulus Cloud | billowy clouds that commonly have a top that resembles cotton balls and a dark bottom |
