Drip the water droplet was enjoying his day at the lake. The sun was especially scorching. Suddenly, Drip didn't feel like himself. The sun's solar radiation was causing Drip to EVAPORATE! Evaporation is when liquid water changes into water vapor.
Drip soon realized he was part of a cloud high above the lake. He was with millions of other cloud droplet friends! Inside the cloud, Drip started to feel like his old self. The cooler temperatures were causing Drip to transform from water vapor into a liquid. Scientists call this process CONDENSATION.
"YIKES!", Drip shrieked as he found himself plummeting towards the ground. Drip had become heavier and gravity was now pulling Drip to Earth as rain. The scientific word for rainfall is PRECIPITATION. Drip was relieved to be in the lake once again.
