=== Weather FrontsRead the information about Weather Fronts ===
 * The purpose of this module is to introduce air masses and weather fronts .. You will be able to describe from where they originate and some basic properties about each air mass affecting the United States. **

=== View: Cold and Warm Front Demonstration ===

Answer the questions below.

 * 1) What happens when different types of are air masses collide?
 * 2)  What are the boundaries of air mass called?
 * 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?
 * 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 Gulf of Mexico in terms of its temperature and moisture.
 * 10) In the area of the Unites states, which way do cold air masses move? (North or South)
 * 11) In the area of the Unites 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 meat 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 three types of fonts?
 * 18) Describe the temperature of the air behind a cold front.
 * ANSWERS: **
 * 1) The cold front pushes the warm front up as they collide.
 * 2) It's called a front.
 * 3) An air mass is a large body of air that has similar temperature and moisture properties throughout.
 * 4) Air masses can be very large.
 * 5) Moist means slightly wet but not dry.
 * 6) If an air mass is humid then that means it's humid.
 * 7) As it moves south it becomes colder and drier southward.
 * 8) It becomes humid and has potential for precipitation.
 * 9) As it travels it gives heat and moisture to the US.
 * 10) North
 * 11) North
 * 12) In Canada air masses ae created very cold and dry due to the winter season.
 * 13) There is a thunderstorm.
 * 14) THey are very big.
 * 15) A front is the boundary between air masses.
 * 16) Warm air goes up..
 * 17) Warm front, cold front, and stationary front.
 * 18) There is prcipatation but it only lasts a few hours.

 * 23) How does the temperature of an area change as a cold front passes?
 * 24) What does precipitation mean?
 * 25) What type of precipitation occurs when a cold front passes?
 * 26) Describe the type of air behind a warm front?
 * 27)  In which direction do warm fronts typically move.
 * 28) What type of precipitation usually occurs when a warm front passes by
 * 29) Label the two fronts on the diagram below:

**ANSWERS:**
 * 1) It is South Dakota.
 * 2) It is Iowa.
 * 3) It's either 55 or 60.
 * 4) The cold pushes the heat. So it gets hotter as it passes.

 * 6) Rain happens.
 * 7) Strong winds occur.
 * 8) Rain happens.
 * 9) The red line thing is the warm front and the blue line thingy is the cold front.

 * 2) How is a warm front diagrammed?
 * 3) What is a stationary front?
 * 4) How is a stationary front diagrammed?
 * 5) When warm air contacts cold air, which air mass typically rises above the other?
 * 6) Which of the following is a diagram of cold front and which is the warm front?

**ANSWER:**
 * 1)  It is going counterclockwise.
 * 2) It is going counterclockwise.
 * 3) A stationary front is an air mass that doesn't move.
 * 4) It is the cool air.
 * 5) Warm air rises.
 * 6) The one with the orange backround is the warm front. The other one is cold.

On the diagram below:
 * 1) How are cold fronts diagrammed?
 * 2)  How many cold front are there on the diagram?
 * 3) In which direction is the front over Washington and Oregon traveling? How do you know?

**ANSWERS:** On the diagram below:
 * 1) It seems to be opposite of the warm front as the blue line thingy.
 * 2) There are 4.
 * 3) It's traveling north. I know this because the cold front seems to be traveling north.
