 * 1) ** What happens when different types of are air masses collide? ** When different types of air masses collide, the cold air pushes the warm air up.
 * 2) **  What are the boundaries of air mass called?  **The boundaries of air mass are called fronts**.**
 * 3) ** Define an air mass? ** An air mass is a large body of air that has similar temperature and moisture properties throughout.
 * 4) ** How large may an air mass be? ** An air mass may be as large as the space or shape it is in.
 * 5) ** What does the term moist mean? ** It means slightly wet, or damp.
 * 6) **If an air mass is humid what does that mean?** It means that it has a high level of water vapor.
 * 7) ** Describe an air mass which forms over Canada in terms of its temperature and moisture. ** An air mass over Canada is continental arctic.  O ne that forms over the Indian ocean is called a maritime tropical air mass.
 * 8) ** Describe an air mass that forms over a desert in terms of its temperature and moisture. ** An air mass over a desert is continental tropical.
 * 9) ** Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. ** An air mass over water in the Gulf of Mexico is maritime tropical.
 * 10) **In the area of the Unites states, which way do cold air masses move?** In the area of the United States, cold air masses move south.
 * 11) **In the area of the Unites states which way do warm air masses move?** In the area in the United States, warm air masses move north.
 * 12) **Why are Canadian air masses considered to be dry air masses?** Canadian air masses are considered to be dry air masses because they form over land.
 * 13) **What happens when a warm humid air mass meet a cold dry air mass?** When warm humid air meets cold dry air a supercell storm is formed.
 * 14) ** Why can cold air masses from Canada make it all the way down to the Gulf of Mexico? ** Cold air from Canada can make it all the way down to the Gulf of Mexico because cold air travels south.
 * 15) ** What is a front? ** A front is the transition zone between two air masses.
 * 16) **What typically happens when two different types of fronts collide?** When two different fronts collide, an occluded front typically happen.
 * 17) ** What are the three types of fronts? ** Three types of fronts are warm, cold, and occluded.
 * 18) ** Describe the temperature of the air behind a cold front. ** The temperature of the air behind a cold front is colder and drier than the air in front of it.
 * 1) ** Looking at the diagram above, which state has a temperature of 38F? ** The state that has a temperature of 38F is South Dakota.
 * 2) ** Looking at the diagram above, which state has a temperature of 55F? ** The state that has a temperature of 55F is Iowa.
 * 3) ** Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! ** I would expect the temperature of Illinois to be colder in three days because the front will hit it in three days. When a cold front hits the temperature drops.
 * 4) **How does the temperature of an area change as a cold front passes?** The temperature gets colder when a cold front passes.
 * 5) ** What does precipitation mean? ** Precipitation means water (solid/liquid) coming back to eart.
 * 6) ** What type of precipitation occurs when a cold front passes? ** When a cold front passes, showers and storms occur.
 * 7) ** Describe the type of air behind a warm front? ** The air behind a warm front is warmer than the air in front of it.
 * 8) **  In which direction do warm fronts typically move.  **  Warm fronts typically move southwest to northeast.
 * 9) ** What type of precipitation usually occurs when a warm front passes by? ** When a warm front passes by, continual precipitation lasting for hours occurs.
 * 10) ** Label the two fronts on the diagram below: ** The two fronts are a cold front(blue) and a warm front(red).
 * 1) ** How is cold front diagrammed? ** A cold front is diagrammed as a blue line with blue triangles pointing foward.
 * 2) ** How is a warm front diagrammed? ** A warm front is diagrammed as a red line with red semi-circles pointing foward.
 * 3) ** What is a stationary front? ** A stationary front is an air mass that does not move.
 * 4) ** How is a stationary front diagrammed? ** A stationary front is diagrammed by alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air.
 * 5) ** When warm air contacts cold air, which air mass typically rises above the other? ** When warm air contacts cold air warm air typically rises.
 * 6) ** Which of the following is a diagram of cold front and which is the warm front? ** The first diagram is of a warm front and the second is of a cold front.
