1) What happens when different types of air masses collide? 2) What are the boundaries of an air mass called? 3) Define an air mass. 4) How large may an air mass be? 5) What does the term moist mean? 6) If an air mass is humid what does that mean? 7) Describe an air mass which forms over Canada in terms of its temperature and moisture. 8) Describe an air mass that forms over a desert in terms of its temperature and moisture 9) Describe an air mass that forms over water in the Gulf of Mexico in terms of its temperature and moisture. 10) In the area of the United States, which way do cold air masses move? 11) In the area of the United States, which way do warm air masses move? 12) Why are Canadian air masses considered to be dry air masses? 13) What happens when a warm, humid air mass meets a cold, dry air mass? 14) Why can cold air masses from Canada make it all the way down to the Gulf of Mexico? 15) What is a front? 16) What typically happens when two different types of fronts collide? 17) What are the 3 types of fronts? 18) Describe the temperature of air behind a cold front.
 * Different weather happens.
 * Fronts.
 * A large area of air with similar properties of temperature and moisture.
 * As large as it's boundaries let it.
 * Moist means "slightly damp/wet".
 * The air is still a bit damp from the last rain (meaning it's warm), and it's also a bit cool. (This also means that since humidity hates my hair, my hair will be a total frizz bomb... and yes, that was a joke.)
 * North
 * South
 * Because since there is usually more cold fronts there, the air is drier.
 * A boundary between two air masses.
 * Cold, warm, and stationary. (There also is occluded)

19) Looking at the diagram above, which state has a temperature of 38F? 20) Looking at the diagram above, which state has a temperature of 55F? 21) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! 22) How does the temperature of an area change as a cold front passes? 23) What does precipitation mean? 24) What type of precipitation occurs when a cold front passes? 25) Describe the type of air behind a warm front. 26) In which direction do warm fronts typically move. 27) What type of precipitation usually occurs when a warm front passes by? 28) Label the two fronts on the diagram below: 29) How is cold front diagrammed? 30) How is a warm front diagrammed? 31) What is a stationary front? 32) How is a stationary front diagrammed? 33) When warm air contacts cold air, which air mass typically rises above the other? 34) Which of the following is a diagram of cold front and which is the warm front?
 * South Dakota
 * Iowa and Illinois
 * I would expect it to be colder because a cold front is coming.
 * The temperature gets colder.
 * Precipitation is rain.
 * Snow.
 * Humid, warm air.
 * They usually move up.
 * Long-lasting showers.
 * The air masses don't move--they are stationary.
 * The warm front.
 * The first diagram is a warm front, the second diagram is a cold front.
