=== 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. **

Answer the questions below.
On the diagram below: On the diagram below:
 * 1) What happens when different types of are air masses collide?/ **They form a weather front, of low pressure.**
 * 2)  What are the boundaries of air mass called?/ **Cold fronts, Warm fronts, Stationary fronts, and Occluded 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?/ **It may be as large as 250 miles.**
 * 5) What does the term moist mean./ **It refers to something wet but not casually very wet.**
 * 6) If an air mass is humid what does that mean?/ **That means there will be precipitation[low pressure]rain, snow, hail, and sleet.**
 * 7) Describe an air mass which forms over Canada in terms of its temperature and moisture.**/You will have cold air masses with a chance of cold precipitation.**
 * 8) Describe an air mass that forms over a desert in terms of its temperature and moisture./ **It forms with high pressure and hot air which means very low precipitation with dry land.**
 * 9) Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture./ **The air masses can form a stationary or a occluded front but there will be precipitation[very moist].**
 * 10) In the area of the Unites states, which way do cold air masses move? (North or South) **South**
 * 11) In the area of the Unites states which way do warm air masses move?**They move to the North.**
 * 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?/ **When two air masses collide.**
 * 16) What typically happens when two different types of fronts collide?
 * 17) What are the three types of fonts?/ **There is a cold front, warm fronts, stationary fronts.**
 * 18) Describe the temperature of the air behind a cold front.
 * 1) Looking at the diagram above, which state has a temperature of 380F?
 * 2) Looking at the diagram above, which state has a temperature of 550F?
 * 3) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN!
 * 4) How does the temperature of an area change as a cold front passes?
 * 5) What does precipitation mean?
 * 6) What type of precipitation occurs when a cold front passes?
 * 7) Describe the type of air behind a warm front?
 * 8)  In which direction do warm fronts typically move.
 * 9) What type of precipitation usually occurs when a warm front passes by
 * 10) Label the two fronts on the diagram below:
 * 1) How is cold front diagrammed?/ **I t is diagrammed with decreasing air putting lots of pressure.**
 * 2) How is a warm front diagrammed?/ **It is diagrammed with rising air which goes slower the the cold front's pressure.**
 * 3) What is a stationary front?/ **It is a front that stops for a long period of time with lots of rain that forms floods, because of the low pressure.**
 * 4) How is a stationary front diagrammed?/ **It is diagrammed with clouds stationed with precipitation in a spot for a long time.**
 * 5) When warm air contacts cold air, which air mass typically rises above the other?**The colder drier of air speeds up fast hits warm moist air and gives humid air.**
 * 6) Which of the following is a diagram of cold front and which is the warm front?
 * 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?
 * 4)  In which direction is the front over North Carolina traveling?
 * 1)  How is the warm front diagrammed?
 * 2)  In which direction is the warm front traveling?
 * 3)  What do you call the front that is over the middle of Canada?

 * 1) ** If it is snowing in Great Neck, what type of air mass must be present?Colder and drier air will be present. **
 * 2) ** If its ** **very hot in October in Great Neck, what type of air mass must be present?Hot moist air which means there will be rain with hot air masses.**
 * 3) Assuming a warm front is moving into the area, there is a stagnant (non-moving) cold air mass around Great Neck, what type of precipitation might we #|expect? How long might it last? **There will**
