The amount of water vapor in the air compared to the amount of water vapor that the air could hold at a specific temperature is called What?
Is it called condensation?

Relative humidity.
The amount of maximum is the Dew Point
The minimum is zero
Anything in between is the relative humidity.
70% means 30% below the dew point.
If the Dew point rises, the humitiy drops.

Relative humidity.
Humidity is the ability of air to hold water. it is expressed in a percentage- the air is holding 10% or 73% of its theoretical maximum. The 'relative' part comes in since warm air holds more than cold air does.
By the way, condensation or dew occurs when the air temps drop.
For example, lets say that air at 80 degrees can hold 100 'units' of water vapor, and it is currently 75% humidity- so it will be holding 75 'units'.
OK, it cools off to 40 degrees. 40 degree air can only hold 50 units of moisture- but the air HAD 75! The extra 25 units will have to condense out because the air simply cannot hold that much. It will show up as dew.
(This is massively simplified- air does not like being at 100% humidity, the vapor is not measured in 'units', etc.- but hopefully you get the picture.)
