| Describe an air mass. | properties of the air are the same (cold, hot etc) and they are classified by where they are formed |
| Where do warm air masses come from? | Tropical regions |
| Where do cold air masses come from? | polar regions |
| Where do dry air masses come from? | from the continent |
| Where do humid air masses come from? | from the ocean |
| Name the four major air masses in the US | Maritime tropical, Maritime Polar, Continental tropical, continental polar |
| What forms a front? | Meeting a two dissimilar air masses |
| Name the four kinds of fronts. | Cold, Warm, Occluded, Stationary |
| How many types of storms are there? | Eight |
| What is a front that has cold air pusing under warm, violent storms, fair cool weather follows? | cold front |
| Name the front that has warm air overtaking cold air, rain and showers, hot humid air follows | warm front |
| Which front has cold fronts moving faster than warm front and over takes it, warm air is pushed up and cold air meets cool air, less extreme weather. | occluded front |
| What front is formed when warm air mass meets cold air mass, no movement occurs, rain may fall for many days. | Stationary front |
| How do meteorologists get information about the weather/ | local observers, balloons, satellites and weather stations around the world |
| What is an isotherm? | curved lines that connect locations with the same temperature. |
| What is an isobar? | curved line that joins places on a weather map that have the same air pressure |
