  • Low density happens when the weather is warm. It causes the air particles to spread out and to move faster.
  • Water Vapor
  • High density happens when the air is cold. The air particles slow down and move closer together.
  • When water evaporates it becomes water vapor. When air is warmer it holds more water vapor. As the water vapor rises they start to cool down.
  • Water Vapor
  • The next step is supersaturation. This is when the water vapor returns to a liquid or solid form.
  • The water droplets form by combining with other things in the air, such as dust, pollution, and sea salt.
  • All of the tiny water droplets form to make clouds.
  • Water droplets combine with other water droplets. They get heavy and fall from the sky.
