| Question | Answer |
|---|---|
| low | a pressure system in which air is rising with clouds and precipitation forming, a cyclone |
| high | a pressure system with dense, sinking air which is associated with pleasant weather, pressure is highest in the center, an anticyclone |
| cloud | forms when air rises, cools and water vapor starts condensing in the sky |
| cumulonimbus | a thunderstorm cloud, dark, puffy and tall |
| wind | created when air moves from an area of high pressure toward an area of low pressure |
| tornado | a whirling column of air over land, occurs in spring, a low pressure center |
| hurricane | a large, rotating low pressure system which gets its energy from warm ocean water |
| warm | the type of front or boundary between a warm air mass and the cold air mass it is replacing, creates light rain |
| cold | the type of front or boundary in which cold air meets warm air it is replacing which causes storms and heavy rain |
| condensation nuclei | a tiny piece of dust or pollution on which water vapor condenses to form clouds |
| nitrogen | this gas makes up 78% of our atmosphere |
| oxygen | this gas makes up 21% of our atmosphere |
| carbon dioxide | this gas and water vapor are the two main greenhouse gases |
| sling psychrometer | an instrument used with a dew-point temperature chart to determine the dew point temperature |
| dew point temperature | the temperature to which the air must be cooled to become saturated |
| troposphere | the lowest layer of atmosphere where most weather occurs |
| air pressure | the effect of the weight of the atmosphere pressing down on a surface area, measured with a barometer |
| humidity | the measure of the water vapor in the air |
| relative humidity | the comparison of how much moisture is in the air to how much moisture the air can hold |
| land breeze | the breeze that blows at night from the land to the sea (warmer air over water = low pressure area) |
| sea breeze | the breeze that blows during the day from the sea to the land (low pressure area from warm air rising) |
| Coriolis Effect | curving of winds, ocean currents caused by Earth's rotation on its axis |
| front | the leading edge of an air mass |
