Why can't you see the water vapor in the air?

• There is very little of it

• It exists as a clear, colorless gas

• It's all far away, in the upper atmosphere

• It's all been condensed

What is the difference between absolute humidity and relative humidity?

• Absolute humidity is expressed as a percentage; relative humidity is expressed as a whole number

• Absolute humidity is how much water the air actually holds;relative humidity represents how much water the air contains as a percentage of how much water the air could possibly hold

• Relative humidity makes the air sticky; absolute humidity makes the air dry

• Absolute humidity represents how much water the air actually holds; relative humidity is how much water the air can hold

Why does it tend to be cool at the Earth's poles?

• They have the worst weather

• They are farthest from the sun

• Sunlight strikes them at extreme angles

• They have high absolute humidity
