Formation

    Water vapor condenses to form liquid water or ice crystals

        Cooling

            cooling air holds less water

            water vapor condenses into droplets or ice crystals

                    dew point - temperature that condensation begins

                        If above freezing - water droplets form

                        If below freezing - ice crystals form

        Particles

            Atmosphere has a variety that allows water on a surface to condense on salt,  dust, blades of grass

            Liquid water on a surface - dew

Types

   Based on shape and altitude

       Cirrus

           wispy, high altitude, fair weather

   Cumulus

       cotton look, between 2km - 18km, fair weather

   Stratus

         flat layers, cover the sky, cloudy
