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

Answer the questions

 * 1)  What are the boundaries of air mass called?
 * 2) Define an air mass?
 * 3) How large may an air mass be?as much as the space or shape it is in.
 * 4) What does the term moist mean. It means slightly wet, or damp.
 * 5) If an air mass is humid what does that mean? that it is cold and warm after raining.
 * 6)  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
 * 7) 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.
 * 8)  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.
