Humidity and Clouds

Humidity is measured in __________.

• tons of water

• gpm, giggles per minute

• g/m³, grams per cubic meter

• percentage

When the temperature decreases, the relative humidity _?_.         

• Increase

• Decrease

• Stay the same

Relative humidity is

• the amount of water vapor present in the air compared to the maximum amount of water vapor that the air can hold at its temperature

• when two places have the same humidity

• a place that always has the same humidity

• none of the above

The weather events associated with humidity are

• earthquakes

• volacnic eruptions

• rain, thunderstorms, blizzards, and droughts

• 50%

• 99%

• 100%

Where can you find water vapor in the air?

• only as rain                     

•  everywhere

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
