What are the boundaries of air mass called?

 * 1) Define an air mass? Air masses are large bodies of air within the same temperature, the best region for air masses are large flat areas.
 * 2) How large may an air mass be? An area can be as large as the area.
 * 3) What does the term moist mean? Moist means wet and humid.
 * 4) If an air mass is humid what does that mean? Humid is the water vapor density.
 * 5) Describe an air mass which forms over Canada in terms of its temperature and moisture. Cold air forms in Canada because it's in the North.
 * 6) Describe an air mass that forms over a desert in terms of its temperature and moisture. Worm fronts move slower then cold fronts and stays by the desert.
 * 7) Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture.
 * 8) In the area of the Unites states, which way do cold air masses move? (North or South) Cold air masses move North in the area of the United States.
 * 9) In the area of the Unites states which way do warm air masses move? Warm air masses move South in the area of the United States.
 * 10) Why are Canadian air masses considered to be dry air masses? Cold fronts bring dry air.
 * 11) What happens when a warm humid air mass meat a cold dry air mass? The cold air pushes the warm air down.
 * 12) Why can cold air masses from Canada make it all the way down to the Gulf of Mexico?
 * 13) What is a front? A front is two air masses between each other.
 * 14) What typically happens when two different types of fronts collide? The cold front pushes the warm air down.
 * 15) What are the three types of fonts? Cold front, Warm front, and stationary fronts.
 * 16) Describe the temperature of the air behind a cold front. The East has 55 degrees and decreeses to 38 degees.
 * 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? Moussori and Indiana
 * 3) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! The temperature in Illinois will get colder with the cold front pushing in, the other states around it are in the 50's
 * 4) How does the temperature of an area change as a cold front passes? The temperature in a cold front area can change up to 15 degrees in one hour.
 * 5) What does precipitation mean? Precipitaion is rain falling from clouds.
 * 6) What type of precipitation occurs when a cold front passes? The warm air rises making clouds and precipitation.
 * 7) Describe the type of air behind a warm front? The air pushes the cold air ahead of it back because of the dense air in warm fronts.
 * 8)  In which direction do warm fronts typically move? Warm front typically move counter clockwise.
 * 9) What type of precipitation usually occurs when a warm front passes by? Light intesity is usually the type of precipitaion in a warm front.
 * 10) Label the two fronts on the diagram below: there is a cold front and a warm front in this diagram.
 * 1) How is cold front diagrammed? The cold air is pushing the warm air up to the cool air.
 * 2) How is a warm front diagrammed? The warm air is being pushed by the cold air up to the cool air.
 * 3) What is a stationary front? Stationary fronts are twon fronts that don't move.
 * 4) How is a stationary front diagrammed? The two fronts are both contacting each other.
 * 5) When warm air contacts cold air, which air mass typically rises above the other? Cool air typically rises above each other.
 * 6) Which of the following is a diagram of cold front and which is the warm front? The one on the left is the warm front because its pushing the cold air and the cold front is on the right because the cold air is pushing the warm air up.

On the diagram below: On the diagram below:
 * 1) How are cold fronts diagrammed? Its labled with high pressure.
 * 2)  How many cold front are there on the diagram? four cold fronts are in the diagram.
 * 3) In which direction is the front over Washington and Oregon traveling? How do you know? It is traveling clockwise becuase the lines are going clockwise.
 * 4) In which direction is the front over North Carolina traveling? The front over North carolina is traveling counter clockwise
 * 1) How is the warm front diagrammed? It is labledwith low pressure.
 * 2) In which direction is the warm front traveling? The warm front is traveling clockwise.
 * 3) What do you call the front that is over the middle of Canada? It is a stationary front.

 * Surface Map - Today (AccuWeather) ||
 * 1) If it is snowing in Great Neck, what type of air mass must be present? Cold air must be present to snow.
 * 2)  If its very hot in October in Great Neck, what type of air mass must be present? Warm air must be present to be very hot.
 * 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? The front won't stay long because the cold air will push the warm air out, It will be very rainy from low pressure.
