2.___-warm air mass slides up over a cool air mass; widespread precipitation develops
3.___-warm air mass and cold air mass meet but never advances; couldiness and precipitation result
4.___-fast-moving cold front overtakes a slower-moving warm front or vice versa; cloudy weather with precipitation

C. Centers of ______
1.___ pressure- air sinks and spreads away from the high-pressure center; moisture cannot rise and condense; usually dry with a few clouds

Since this is not my area of expertise, I searched Google under the key words "air masses" to get these possible sources:

http://en.wikipedia.org/wiki/Air_mass
http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/af/home.rxml
http://www.usatoday.com/weather/tg/wamsorce/wamsorce.htm
http://www.physicalgeography.net/fundamentals/7r.html
http://cimss.ssec.wisc.edu/wxwise/class/frntmass.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
