| Question | Answer |
|---|---|
| a high-level cloud | cirrostratus |
| a mid-level cloud | nimbostratus |
| cooling air becomes saturated at a temperature called the | dew point |
| what type of drought occurs when precipitation cannot supply enough moisture to the ground to support an area's crops | agricultural |
| what type of drought is based on a water shortage's effect on people | socioeconomic |
| which type of cloud forms a flat, gray layer of heavy clouds not far above the ground | stratus |
| Which type of front forms when a warm air mass moves into a region occupied by a cold air mass | warm front |
| which type of front forms a Y shape | occluded front |
| precipitation made of ice crystals that fall to the ground is called | snow |
| which type of air mass brings cool, wet weather | maritime polar |
| which type of air mass brings warm, moist weather | maritime tropical |
| the process of liquid becoming a gas is | evaporation |
| when the temperature of air rises, relative humidity will | decrease |
| the year-round atmospheric conditions typical of a certain place are its | climate |
| the movement of water from the earth's surface, into the air and back to the surface is the | water cycle |
| an almond-shaped cloud is | lenticular |
| an air mass that brings very cold and dry weather | arctic |
| a low that forms along a front is called | frontal cyclone |
| which type of front forms when two air masses push against each other but neither advances | stationary |
| what is a mixture of smoke and fog | smog |
| what is the amount of water vapor in the air called | humidity |
| what phenomenon occurs when an area receives an abnormally low amount of precipitation over a long period | drought |
| what is rain that freezes before it hits the ground | sleet |
| what is the study of weather and of the atmospheric conditions that produce weather | meterology |
| what phenomenon occurs when an air mass remains stationary over a region for a long time | air-mass weather |
| three factors that affect density of an air mass | temperature humidity pressure |
| a substance going from a solid to a liquid is | melting |
| water vapor in the air that touches the ground and turns to ice is | frost |
| water vapor in the air that touches the cooler ground and turns to a liquid | dew |
| ice crystals in clouds that grow large enough to fall to the ground are | snowflakes |
| layered balls of ice are called | hailstones |
| white, billowy clouds that resemble piles of cotton puffs are | cumulus |
| what type of fog is found along the slopes of mountains | upslope fog |
| drops of liquid water that have a diameter of 0.5 millimeter or greater and fall from the clouds to Earth are called | rain |
| snowflakes with white, feathery branches forming a leaf or star shaped pattern are | dendrites |
| air that is completely full of water vapor and can hold no more is considered | saturated |
| the most frequent type of cloud is | stratocumulus |
| the ratio comparing the actual humidity to the humidity of saturated air under the same conditions is | relative humidity |
| a large body of air with relatively uniform properties is a | air mass |
| airborne water vapor cannot turn into liquid without a small particle called | condensation nucleus |
| the 3 major factors that determine the earth's weather are | heat energy uneven distribution of heat energy water vapor |
| a thick, brownish haze that results from complex molecules released into the air by vehicles and some factories and plants is | photochemical smog |
