| Question | Answer |
|---|---|
| Albedo | Percent of solar radiation relected by a surface |
| Atmospheric Pressure | Ratio of the weight of the air to the area of the surface on which it presses |
| Barometer | Instrument that measures atmospheric pressure |
| Climate | General weather conditions over many years |
| Conduction | Type of energy transfer in which vibrating molecules pass heat along to other vibrating molecules by direct contact |
| Convection Cell | Looping pattern of flowing air |
| Doldrums | Narrow zone of low air pressure at the equator characterized by weak and undependable winds |
| Electromagnetic Spectrum | Complete range of wave lengths of radiation |
| Exosphere | Layer of the atmosphere above the ionosphere that merges with interplanetary space |
| Greenhouse Effect | Process by which the atmosphere traps infrared rays over the earth's surface |
| Horse Latitudes | Subtropical high-pressure belt of air, around 30 degrees latitude |
| Ionosphere | Lower region of the thermosphere, at an altitude of 80 to 550 km |
| Jet Streams | Bounds of high-speed, high-altitude westerly winds |
| Mesopause | Upper boundary of the mesosphere, marked by an increase in temperature |
| Mesosphere | Coldest layer of the atmosphere that extends upward from the stratosphere to an altitude of about 80 km |
| Nitrogen Cycle | Process in which nitrogen moves from the air to the sil to animals and back to the air |
| Ozone | Form of atmospheric oxegyn that has three atons per molecule |
| Polar Easterlies | Weak global winds located north of 65 degrees north latitude and south of 65 degrees south latitude that flow away from the poles |
| Standard Atmosphere Pressure | The atmospheric pressure measured at sea level |
| Stratopause | High-temperature zone that marks the upper boundary of the stratosphere |
| Stratosphere | Layre of the atmosphere that extends upward from the troposphere to an altitude of 50 km; contains most atmospheric ozone |
| Subpolar Low | Belt of low air pressure at about 60 degrees north and 60 degrees south latitude |
| Temperature Inversion | Atmospheric condition in which warm air traps cooler air near the earth's surface |
| Thermosphere | The atmospheric layer above the mesosphere |
| Trade Winds | Global winds flowing toward the equator between 30 degrees and 0 degrees latitude |
| Tropopause | Upper boundary of the troposphere in which the temperature remains almost constant |
| Troposphere | Atmospheric layer closest to the earth's surface where nearly all weather occurs |
| Weather | General condition of the atnosphere at a particular tine and place |
| Westerlies | Global winds located between 40 degrees and 60 degrees latitude that flow from the southwest in the Northen Hemisphere and from the northwest in the Southwest Hemisphere |
