 * 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. **
 * === Weather FrontsRead the information about Weather Fronts ===
 * === View: Cold and Warm Front Demonstration ===
 * ===Answer the questions below.===
 * 1) What happens when different types of are air masses collide? In the warn front it gets warmer in a cold front it get colder
 * 2) What are the boundaries of air mass 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? Big areas.
 * 5) What does the term moist mean. Slightly damp.
 * 6) If an air mass is humid what does that mean? Hot and damp at the same time.
 * 7) Describe an air mass which forms over Canada in terms of its temperature and moisture. Because of the longer nights it is colder and stable.
 * 8) Describe an air mass that forms over a desert in terms of its temperature and moisture. Shorter nights and very hot.
 * 9) Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. Oringinate over the warm water of the tropics and the Gulf of Mexico.
 * 10) In the area of the Unites states, which way do cold air masses move? (North or South) The North is colder.
 * 11) In the area of the Unites states which way do warm air masses move? It move North
 * 12) Why are Canadian air masses considered to be dry air masses? They don't as much rain as us and there not as hot if a state is hot and rainy it will be humid.
 * 13) What happens when a warm humid air mass meat a cold dry air mass? It becomes a warn front
 * 14) Why can cold air masses from Canada make it all the way down to the Gulf of Mexico?Fronts
 * 15) What is a front? A front is transition between two air masses.
 * 16) What typically happens when two different types of fronts collide? it get to the perfict weather
 * 17) What are the three types of fonts? cold front warn front
 * 18) Describe the temperature of the air behind a cold front. cold.
 * 1) Looking at the diagram above, which state has a temperature of 380 F? Colorado
 * 2) Looking at the diagram above, which state has a temperature of 550 F? Alabama
 * 3) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! It would be like 56 f because the cold front is coming and it not quite there yet.
 * 4) How does the temperature of an area change as a cold front passes? It going down
 * 5) What does precipitation mean? when the rain is in the sky
 * 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?The cold air moves into the warm air
 * 2) How is a warm front diagrammed?The warm air moves into the cold air.
 * 3) What is a stationary front? A front that stays in the same spot.
 * 4) How is a stationary front diagrammed? The the warm air moves into the cold air in it stays in the same spot.
 * 5) When warm air contacts cold air, which air mass typically rises above the other the cold air.
 * 6) Which of the following is a diagram of cold front and which is the warm front? the first one

On the diagram below: On the diagram below:
 * 1) How are cold fronts diagrammed? the warm air goes into the cold air
 * 2) How many cold front are there on the diagram? there are three
 * 3) In which direction is the front over Washington and Oregon traveling? How do you know east because the blue is moving that way.
 * 4) In which direction is the front over North Carolina traveling?south
 * 1) How is the warm front diagrammed? With blue and red arows and letters
 * 2) In which direction is the warm front traveling? north
 * 3) What do you call the front that is over the middle of Canada?cold and warn fronts

 * 1) If it is snowing in Great Neck, what type of air mass must be present?polor air
 * 2) If its very hot in October in Great Neck, what type of air mass must be present?tropical
 * 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?2 month and polor air
