A water droplet starts when cooled water particles in clouds condense. These particles originally evaporated from bodies of water and formed into water vapor.
Here's a breakdown of the process:
- Evaporation: The sun heats water molecules, turning them into water vapor. This process is called evaporation.
- Rising Air: This water vapor rises into the air.
- Condensation: As the water vapor rises, it cools down. When it cools, it changes back into a liquid. This process is called condensation, and it forms clouds.
- Droplet Formation: Over time, the cooled water particles in the cloud join together to form water droplets, as described in the reference material. These droplets eventually become heavy enough to fall as rain.
In summary, evaporation, rising air, and condensation are all required for a water droplet to form.
