= Weather Front Questions =  ** 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? **It makes a warm, cold, stationary, contenental Arctic or occluded front(s).**
 * 2) What are the boundaries of air mass called? **A front.**
 * 3) Define an air mass. An air mass is a large body of air that has similar temperature and moisture properties throughout. **Maritime Tropical: begin of warm water of tropics and Gulf of Mexico. When tropical air masses transporst warm/moist air over to the United States, enlarging the chance of presipiation.**
 * 4) How large may an air mass be? **An air mass can cover thousands of square miles, some masses can be very small too.**
 * 5) What does the term moist mean. **Moist- slightly wet, damp, or humid. Its also a adjective.**
 * 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.
 * 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! **58-57, because there are other similar tempatures around it.** ** In three days the tempature will drop. **
 * 4) How does the temperature of an area change as a cold front passes? **The air is colder and dryer than the air ahead of it.**
 * 5) What does precipitation mean? **Precipitation- rain, snow, sleet, or hail that falls to the ground.**
 * 6) What type of precipitation occurs when a cold front passes? **Rain/Thunderstorms**
 * 7) Describe the type of air behind a warm front. **The type of air behind a warm front is hotter and more moist.**
 * 8) In which direction do warm fronts typically move. **South - Southeast**
 * 9) What type of precipitation usually occurs when a warm front passes by? **Light rain, sleet, snow, or drizzle.**
 * 10) Label the two fronts on the diagram below: **Cold and Warm Fronts.**

 * 3) What is a stationary front? **Is a pair of air masses.** [[image:https://upload.wikimedia.org/wikipedia/commons/thumb/d/d3/Stationary_front_symbol.svg/220px-Stationary_front_symbol.svg.png]]
 * 4) How is a stationary front diagrammed? **( Picture Above)**
 * 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?
 * 1. Warm Front**  **2. Cold 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?
