HumidityThe amount of moisture in the air.How much water is there in the air?

Relative HumidityThe amount of moisture in the air compared

with the amount it can holdMeasured in percent from 0 to 100%(Humidity / Amount it can hold) x 100

Dew PointThe temperature at which the air is saturated

(100%) and condensation forms.Example: water on the side of your pop can.

FogA cloud that is formed when air is cooled and

it’s dew point is near the ground
