* Cooling: As air rises, it expands and cools. This cooling reduces the capacity of the air to hold water vapor.
* Condensation: When the air cools below the dew point (the temperature at which air becomes saturated with water vapor), water vapor begins to condense into tiny water droplets.
* Nucleation: These droplets need a surface to form on, and that's where dust and salt particles come in. They act as condensation nuclei, providing a surface for the water vapor to condense around.
* Cloud formation: As more water vapor condenses, the droplets grow and become visible as clouds. The type of cloud formed depends on the temperature and altitude, as well as the size and type of condensation nuclei.
So, in short, the cooling of water vapor leads to its condensation, and dust and salt particles provide a surface for this condensation to occur, ultimately leading to cloud formation.
