| Term | Definition |
|---|
| refers to the present stae of the atmosphere and describes current conditions | weather |
| weather is affected by: t | temperature |
| weather is affected by: w | wind |
| weather is affected by: h | humidity |
| weather is affected by: a | air pressure |
| the water cycle and the ___ form the basis of weather | sun |
| the _____ and the sun form the basis of weather | water cycle |
| the ___ heats air | sun |
| the sun ________ water | evaporates |
| the sun creates ______ | wind |
| the sun creates wind by heating the atmosphere _____________ | unevenly |
| Different temperatures = different ______ | pressures |
| air moves from high to low pressure creating | wind |
| the amount of water vapor help in the air. water vapor molecules fit into spaces between molecules that make up the air | humidity |
| higher temperatures allow for ______ humidity b/c high energy molecules prevent _________ | more, condensation |
| when air is said to be holding as much water as possible, it is said to be | saturated |
| the temp. at which air is saturated and condensation takes place is called the | dew point |
| __________ form as warm air is forced up, expands and cools | clouds |
| layers, even sheets, low altitude, indicates fair weather --> drizzle. may form fog | stratus |
| puffy, white, flat base. medium altitude. indicates fair weather --> thunderstorms | cumulus |
| fibrous, curly, high, thin, white, feathery. indicates approaching storm | cirrus |
| precipitation: warm temp. | rain |
| precipitation: cold temp. | snow |
| precipitation: snow passes through a layer of warm air, melts, then refreeze near the ground | sleet |
| precipitation: forms in cumulus clouds during a thunderstorm | hail |
| air is dense --> sinks. clouds cant form, clear sky ---> sunny day : ______ pressure | high |
| air rises and cools --> at a certain elevation the air reaches its dew oint, water vapor condenses and a cloud is formed ---> rainy weather : __________ pressure | low |
| precipitation over a large area : _________ front | warm |
| precipitation over small area w/ violent storms : ____________ front | cold |
| strong winds and heavy precipitation : _______ front | occluded |
| fronts stop at one anotherthere is light wind and precipitation for several days | stationary |
