What does it mean when air is said to be saturated?

• when it has more than enough oxygen in it

• when it contains the maximum amount of water vapor that it can hold at that temperature

• when the dew point temperature is 10 degrees higher than the air temperature

• when the amount of water vapor as at 50%

What is relative humidity?

• the percent of cloud cover in the sky

• the amount of water vapor minus the amount of carbon dioxide in the atmosphere

• the humidity related to the amount of solar radiation for that day

• the ratio of the actual amount of water vapor in the air to the amount of water vapor that air temp can hold
