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
TemperatureThe average kinetic energy.
EvaporationWhen water changes from liquid to gas.
CondensationWhen water changes from gas to liquid
PrecipitationWater falling from clouds.Includes:

When clouds become saturated
CloudsCondensation of water in the atmosphere
Barometric PressureThe force of air molecules pushing down
