10/1/13 26th Day of School Learning Goal: I will be able to explain how weather changes as air masses move. Due Today: Quiz corrections/index cards Evening Assignment: Complete index cards for information about air masses.

Do Now 1) Watch a weather broadcast on wral.com wral.com 2) In your science notebook write down any weather terms that you hear or see.

On the front of nine cards write the following terms in big, bold letters: Air mass Continental Maritime Tropical Polar Continental polar Maritime polar Continental tropical Maritime tropical Use your index cards to collect information about air masses. On the back side of the index card write in your own words the following information about each one: 1.Definition of term 2.Characteristics of air mass 3.Location of where you would find the air mass 4.Effects of air mass on weather

Air mass vocabulary flashcards example 1.Definition: An air mass is a large volume of air in which temperature and humidity are nearly the same over a large area. 2.Characteristics: large body of air (size of states) changes temperature & humidity when it arrives Picks up temperature and humidity over area where it forms 3.Where it forms: over land (dry) or sea (moist); north (cool) or south (warm) 4.Weather: changes temperature (warm/cool) & humidity (moist/dry) when it arrives McDougall, p.
