| Question | Answer |
| A large body of air which has uniform temperature and humidity | air mass |
| the weight of the air pushing down on the earth | air pressure |
| air movement around a "low" | counterclockwise |
| area of few clouds, light winds, and no precipitation | eye |
| a line connecting points of equal air pressure | isobar |
| what cirrus clouds are made of | ice crystals |
| a boundary between two cold air masses that have lifted up a warm air mass | occluded front |
| small, funnel-shaped cloud with rapidly rotating winds | tornado |
| the movement of air over the earth | wind |
| The measure of the amount of heat that an object has | temperature |
| Weather is affected most by this | temperature |
| The tendency of moving objects to curve due to the rotation of the earth | Coriolis effect |
| Winds in the Northern Hemisphere curve this direction | to the right |
| The comparison of the actual amount of water vapor in the air to the maximum amount it can hold is known as | relative humidity |
| Air in the continental polar air mass is | cold and dry |
| The gentle lifting of warm, moist air as it moves up and over colder air will form | nimbostratus clouds |
| The front produced by warmer air pushing colder air is | warm front |
| A hurricane will die out when | it reaches land |
| Before a meteorologist can predict future weather, he or she must know | the present and past weather conditions |
| Winds from the west and a rising barometer forecast | fair weather |
| Major changes in the weather are indicated by | rapid changes in the barometer |
| Nimbo- in nimbostratus and cumulonimbus means | rain clouds |
| Tornadoes over oceans become | waterspouts |
| A barometer is used to measure | air pressure |
| Relative humidity is effected by the | temperature |
| The temperature at which the air becomes saturated with water vapor is the | dew points |
| The area of precipitation is located ________ the cold front | on both sides |
| The boundary between two air masses that are moving parallel to each other is called a ________ front | stationary |
| Most violent storms form in ______ air masses | maritime tropical |
| True/False? Fair weather is usually found around a high | true |
| True/False? Man is able to predict the weather because God created an orderly world | true |
| True/False? Weather sayings like Groundhog Day are useful in predicting the weather | false |
