Air Pressure:    
Air pressure, also known as atmospheric pressure, is the weight of air above a given point.  Higher pressures usually mean clear weather because air is sinking toward the earth. Lower pressures usually mean bad weather because air is rising.

Barometer:     
A barometer is an instrument used to measure air pressure. Air pressure is usually expressed in units of millibars (mb) or inches of mercury (in. Hg.). At sea level, standard air pressure is 1013.25 mb. or 29.92 in. Hg.
Cloud Formation :   
Clouds form as air rises, expands and cools. This expansion and cooling causes condensation to occur. Condensation is simply the process by which water vapor turns to water.



Fronts:      
A front is the transition zone between two different air masses with different temperatures and humidity levels.

Humidity:   
Humidity is the amount of water vapor in the air.

  1. Hi. For the glossary, do we write it in our lab or regular?
