1. air is warmed near earth's surface
2. water vapor rises and comes in contact with cooler air
3 water vapor condenses onto partials etc.
4 water enters the atmosphere through evaporation
5 clouds are born
warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules. This leads to the idea that as air cools its molecules move closer together, “squeezing” out water vapor.
