Study Notes
Cloud Formation and Characteristics
- Clouds are collections of tiny water droplets or ice crystals suspended in the air, often visible as white or gray masses
- Clouds are formed when water vapor in the air cools and condenses into visible liquid droplets or ice crystals
- Water vapor is water in its gaseous state, formed when the temperature and humidity in the air are suitable for evaporation
- Clouds appear white because of the way that light scatters off the water droplets or ice crystals, giving them a bright, opaque appearance
- When clouds absorb or mix with other substances, such as pollutants or dust, they can take on a grayish hue, indicating a change in their composition or environment
