1. 11.2 State of the Atmosphere

2. Temperature vs. Heat Heat and temp are 2 different concepts
Temp is the measurement of how rapidly molecules move around
The faster they move the warmer it is
Heat is the transfer of energy that occurs because of a difference in temp (higher to lower)

3. Dew Point
Dew point is the temp at which air must be cooled at constant pressure to reach saturation
Saturation is the point at which the air holds as much water vapor as possible
Condensation occurs when matter changes state from a gas to a solid

4. Temperature Inversion
Temp and pressure in the overall troposphere decrease with height
The exception is with a temperature inversion
This is an increase in temp with height

8. Relative Humidity
Air in the lower portion of the atmosphere always contains a little bit of water vapor
This is called humidity
The ratio of water vapor in a volume of air relative to how much water vapor that air is capable of holding is called relative humidity (expressed as a percent)
Warm air can hold more moisture then cold
