Weather+Front+Questions+MattMa


 * 1) **.What happens when different types of air masses collide?** When they collide, it creates clouds.
 * 2) ** What are ** **the boundaries of air mass called?** The boundaries are called fronts.
 * 3) **Define an air mass.** An air mass can be defined as a large body of air. They have similar temperature and moisture characteristics.
 * 4) **How large may an air mass be?** An air mass can be as large as however long it takes to take on the characteristics of the surface down below.
 * 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 is cold and warm after raining.
 * 7) **Describe an air mass which forms over Canada in terms of its temperature and moisture.** The continental polar air masses form over Canada which give colder and drier air to the south.
 * 8) **Describe an air mass that forms over a desert in terms of its temperature and moisture.** A maritime tropical air mass
 * 9) ** Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. **The maritime air masses have warm temperatures and rich moisture.
 * 10) **In the area of the Unites states, which way do cold air masses move?** They move north.
 * 11) **In the area of the Unites states which way do warm air masses move?** They move south.
 * 12) **Why are Canadian air masses considered to be dry air masses?** They are considered to be dry because it is cold over the northern plains of Canada.
 * 13) **What happens when a warm humid air mass meet a cold dry air mass?** It makes a cloud.
 * 14) **Why can cold air masses from Canada make it all the way down to the Gulf of Mexico?** Cold air masses can do this because they start at Canands and always move southward.
 * 15) ** What is a front? ** A front is a transition zone between air masses.
 * 16) **What typically happens when two different types of fronts collide?** They create clouds.
 * 17) **What are the three types of fonts?** Three types of fronts are cold, warm, and occluded fronts.
 * 18) ** Describe the temperature of the air behind a cold front. ** The temperature is colder and drier than the air ahead of it.
 * 1) **Looking at the diagram above, which state has a temperature of 38F?** The state of South Dakota.
 * 2) **Looking at the diagram above, which state has a temperature of 55F?** The state of Iowa.
 * 3) ** Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! ** The cold front would bring colder air to Illinois.
 * 4) ** How does the temperature of an area change as a cold front passes? ** The temperature will drop more than 15 degrees within the first hour.
 * 5) ** What does precipitation mean? ** Precipitation is liquid or solid water that falls back to the Earth.
 * 6) **What type of precipitation occurs when a cold front passes?** A cold front brings showers and developing storms.
 * 7) ** Describe the type of air behind a warm front? ** There is warm air advancing onto cold air.
 * 8) **  In which direction do warm fronts typically move?  **  It usually moves from southeast to northeast.
 * 9) ** What type of precipitation usually occurs when a warm front passes by? ** A long period of showers passes by with a warm front.
 * 10) **Label the two fronts on the diagram below:** There is a cold and warm front.
 * 1) **How is cold front diagrammed?** It is diagrammed as a blue line with triangles.
 * 2) ** How is a warm front diagrammed? ** It is diagrammed as a red line with half circles.
 * 3) ** What is a stationary front? ** Stationary fronts are two air masses that don't move.
 * 4) ** How is a stationary front diagrammed? ** It is diagrammed with alternating blue triangles and red half circles.
 * 5) **When warm air contacts cold air, which air mass typically rises above the other?** The warm air would rise above it and bring warmer air.
 * 6) **Which of the following is a diagram of cold front and which is the warm front?** The orange and teal one is of a warm front, and the yellow and blue one is of a cold front.
