=== 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? __A front is created as a transition zone between the two air masses.__
 * 2) What are the boundaries of air mass called? __They 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? __They can be up to 20000 feet high.__
 * 5) What does the term moist mean. __It means that it is warm and humid.__
 * 6) If an air mass is humid what does that mean? __It means there is a lot of moisture.__
 * 7) Describe an air mass which forms over Canada in terms of its temperature and moisture.__Cold and, humid summer.__
 * 8) Describe an air mass that forms over a desert in terms of its temperature and moisture. __Dry and hot.__
 * 9) Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. __Tropical, hot, and rains often.__
 * 10) In the area of the Unites states, which way do cold air masses move? __(North or South) It moves counter clockwise.__
 * 11) In the area of the Unites states which way do warm air masses move? __They move clockwise.__
 * 12) Why are Canadian air masses considered to be dry air masses? __Canada is up north where dry cold fronts come down into southern america.__
 * 13) What happens when a warm humid air mass meets a cold dry air mass? __The warm air moves where the cold is not going which is north in a counterclockwise pattern.__
 * 14) Why can cold air masses from Canada make it all the way down to the Gulf of Mexico? __The cold mass can go far distances and nothing can stop as a warm front will slide above it.__
 * 15) What is a front? __Is an area between two air masses__.
 * 16) What typically happens when two different types of fronts collide? __When the cold front hits the warm front the warm front will fly up and when the warm front hits t goes up at 45 degree angle besides when the cold hits is 90 degree angle.__
 * 17) What are the three types of fonts? __Cold front, Warm front, and Stationary front__
 * 18) Describe the temperature of the air behind a cold front. __Colder temperatures like 28 F or 31 F__
 * 1) Looking at the diagram above, which state has a temperature of 380F? South Dakota
 * 2) Looking at the diagram above, which state has a temperature of 550F? Iowa
 * 3) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! I would expect it to be warmer as the cold front has gone away.
 * 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?
 * 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?

On the diagram below: 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?
 * 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?
 * 2)  If its very hot in October in Great Neck, what type of air mass must be present?
 * 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?
