What happens when different types of are air masses collide? They are called fronts.
 * 1)  What are the boundaries of air mass called? They are called fronts.
 * 2) Define an air mass? An air mass is a large body of air that has similar temperature and moisture properties throughout.
 * 3) How large may an air mass be? It is as large as synoptic.
 * 4) What does the term moist mean? It means that is is wet, but not too wet.
 * 5) If an air mass is humid what does that mean? The air is thick and moist.
 * 6) Describe an air mass which forms over Canada in terms of its temperature and moisture.The air mass that forms over Canada is Continental Artic Air and its is very cold and very dry air.
 * 7) Describe an air mass that forms over a desert in terms of its temperature and moisture.The air mass that forms over a desert is continental tropical air and its is veryhot and dry air.
 * 8) Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. The air mass that forms over desert is Maritime Tropical air is hot and humid air.
 * 9) In the area of the Unites states, which way do cold air masses move? (North or South) It moves South.
 * 10) In the area of the Unites states which way do warm air masses move? It move North.
 * 11) Why are Canadian air masses considered to be dry air masses? It is considered that because Canada does not get a lot of rain.
 * 12) What happens when a warm humid air mass meet a cold dry air mass?It creates a cumulonibus cloud.
 * 13) Why can cold air masses from Canada make it all the way down to the Gulf of Mexico? It would eventualy get warm by conducting warm air into it.
 * 14) What is a front? When a air mass boundries meet together.
 * 15) What typically happens when two different types of fronts collide? It creates thunderstorms.
 * 16) What are the three types of fronts? Warm, Cold And Stationary Fronts.
 * 17) Describe the temperature of the air behind a cold front. The air behind it became colder than in front it.
 * 1) Looking at the diagram above, which state has a temperature of 380F? South Dakota
 * 2) Looking at the diagram above, which state has a temperature of 550F? Iowa
 * 3) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! It could be staying in the low 60's and in the high 50's
 * 4) How does the temperature of an area change as a cold front passes? The air becomes colder.
 * 5) What does precipitation mean? It means when water comes drops from the clouds.
 * 6) What type of precipitation occurs when a cold front passes? Snow.
 * 7) Describe the type of air behind a warm front? Warm and moist air.
 * 8)  In which direction do warm fronts typically move. They move upwards.
 * 9) What type of precipitation usually occurs when a warm front passes by. Rain.
 * 10) Label the two fronts on the diagram below: Red:Warm fronts Blue:Cold fronts
 * 1) How is cold front diagrammed? The cold front is moving in a counter-clockwise way.
 * 2) How is a warm front diagrammed? The warm front is moving in a upwards circular motion.
 * 3) What is a stationary front? ignore
 * 4) How is a stationary front diagrammed?ignore
 * 5) When warm air contacts cold air, which air mass typically rises above the other? The warm air rises.
 * 6) Which of the following is a diagram of cold front and which is the warm front? .The first one is a warm front and the cold front is the second one.

On the diagram below: On the diagram below:
 * 1) How are cold fronts diagrammed? the cold air is pushing the warm air upwards.
 * 2)  How many cold front are there on the diagram? 3
 * 3) In which direction is the front over Washington and Oregon traveling? How do you know? It is moving south and the diagram shows it.
 * 4) In which direction is the front over North Carolina traveling?Upwards
 * 1) How is the warm front diagrammed? It is moving upwards.
 * 2) In which direction is the warm front traveling? It is moving north.
 * 3) What do you call the front that is over the middle of Canada? ignore
