 * 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. ** Cold or hot. An air mass is a large body of air that has similar temperature and moisture properties throughout.

Answer the questions below.
> ==// **The temperature may be 55 degrees in three days because the 55 degrees in Indiana will move to the left and down towards Illinois.** //== > ==// **Long rain showers occur during the warm front, it could take up at least 24 hours.** //==
 * 1) **What happens when different types of air masses collide? //When they collide they create clouds.//**
 * 2) ** What are the boundaries of air mass called? // The boundaries 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? //An air mass may be as large as much of the space or shape it is in.// **
 * 5) ** What does the term moist mean. //Moist// //means slightly wet, or damp.// **
 * 6) ** If an air mass is humid what does that mean? //If an air mass is humid it will be// //cold and warm after raining.// **
 * 7) ** Describe an air mass which forms over Canada in terms of its temperature and moisture. //O// // ne that forms over the Indian ocean is called a maritime tropical air mass //**
 * 8) ** Describe an air mass that forms over a desert in terms of its temperature and moisture. //It is ever hot and humid plus there is ever little water in the desert.// **
 * 9) ** Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. //Masses of air that travel south from the wide expanses of land in Canada, and north from the warm waters of the Gulf of Mexico.//**
 * 10) ** In the area of the Unites states, which way do cold air masses move? (North or South) //It is north// **
 * 11) ** In the area of the Unites states which way do warm air masses move? //It is South// **
 * 12) ** Why are Canadian air masses considered to be dry air masses? //It is ever hot over other in Canada// **
 * 13) ** What happens when a warm humid air mass meat a cold dry air mass? //When a warm air mass meets a cold dry mass it makes a Columbus cloud.// **
 * 14) ** Why can cold air masses from Canada make it all the way down to the Gulf of Mexico? //It can't make it.// **
 * 15) ** What is a front? //A front is the transition zone between two air masses.// **
 * 16) ** What typically happens when two different types of fronts collide? ** //I**nteractions along the edge of this front often results in showers and storms developing, as the warmer air is pushed upward by the advancing colder air.**//
 * 17) ** What are the three types of fonts? //Warm fronts, Cold fronts, and Stationary fronts.// **
 * 18) == ** Describe the temperature of the air behind a cold front. //It is colder and drier// ** // **than the air ahead of it.** //==
 * 1) ** Looking at the diagram above, which state has a temperature of 38F? //It is South Dakota// **
 * 2) ** Looking at the diagram above, which state has a temperature of 55F? //It is// //Iowa// **
 * 3) ** Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! **
 * 1) ==** How does the temperature of an area change as a cold front passes? **// **The temperature can drop more than 15 degrees within the first hour.** //==
 * 2) ** What does precipitation mean? //Precipitation means// r//ain, snow, sleet, or hail that falls to the ground.// **
 * 3) ** What type of precipitation occurs when a cold front passes? //When a cold front passes it usually results in showers and storms// //developing.// **
 * 4) ** Describe the type of air behind a warm front? //The air behind a warm front is warmer and more humid than it was before.// **
 * 5) **  In which direction do warm fronts typically move? //The Warm Front typically moves to the right and up.//  **
 * 6) ** What type of precipitation usually occurs when a warm front passes by? **
 * 1) ** Label the two fronts on the diagram below: There is a Cold //front and Warm front.// **
 * 1) **How is cold front diagrammed? //A cold front are always indicated by a blue line with forward pointing blue triangles.//**
 * 2) ** How is a warm front diagrammed? //A warm front is always indicated by a red line with froward pointing red semi-circles.// **
 * 3) ** What is a stationary front? //A stationary front is when a warm or cold front stops moving.// **
 * 4) ** How is a stationary front diagrammed? //It is represented by alternating blue and red lines with blue triangles pointing towards the warmer air and red semi-circles pointing towards the colder air.// **
 * 5) ** When warm air contacts cold air, which air mass typically rises above the other? //The warm air rises.// **
 * 6) ** Which of the following is a diagram of cold front and which is the warm front? //The first picture is the warm front, and the second picture is the cold front.// **
