• relative humidity
• humidity

• cumulus cloud
• stratus cloud
• cirrus cloud
• cloud 9

Why doesn't cloud formation take place until the dew-point temperature is reached?

• because dew-point is the temperature at which water vapor condenses into water droplets
• cloud formation can take place at any temperature, and does not depend on the dew-point temerature
• because water sublimates at the dew-point temperature
• the dew-point temperature only applies on Earth's surface, not in the atmosphere
