Greenhouse Effect
Fig. 3: http://www.nps.gov/goga/naturescience/images/Greenhouse-effect.jpg
Air Mass•Air mass: a large expanse of the
atmosphere with relatively uniform temperature and humidity. ▫Moves both horizontally (parallel to the
Earth’s surface) and vertically.
•Front: the line where two air masses of different temperature and humidity meet.
Atmospheric Pressure
1. Number of air molecules
2. Temperature of air
3. Move from high-pressure areas to low-pressure areas, resulting in winds.
