| Question | Answer |
|---|---|
| The State of the Atmosphere at a given time and place | Weather |
| Temperature, moisture, wind, air pressure | Weather |
| The layer of gases surrounding earth composed mainly of nitrogen and oxygen | Atmosphere |
| Lowest layer of the atmosphere. Weather occurs in this layer | Troposphere |
| Second layer of the atmosphere ~ Jets fly through ozone found here | Stratosphere |
| Middle layer of the atmosphere. Meteors burn up here. | Mesosphere |
| Upper layer of the atmosphere. Northern Lights. Space Shuttle | Thermosphere |
| Layer of the atmosphere that merges with space | Exosphere |
| Air pollution can be | Global, Regional, & Local |
| Layer of atmosphere; gas made of three oxygen atoms (03); absorbs 99% of sun's harmful UVB rays | Ozone layer |
| Don't sunbathe; the sun is radiation tanning also increases your risk. Avoid the sun especially between 10 am & 4 pm. | Ways to avoid skin cancer |
| Seek shade; wear a shirt (thicker & darker); wear sunglasses; be especially weary fair skinned people. | Ways to avoid skin cancer |
| The pressure caused by the weight of the atmosphere | Air pressure |
| As elevation increases, air pressure | decreases |
| An instrument that measures air pressure. | Barometer |
| Warm air rises, cool air | sinks |
| Travels from areas of high pressure to areas of low pressure | Wind |
| Form where cold air moves towards warm air. Creates rain storms | Cold Front |
| Form where warm air moves toward cold air. | Warm Front |
| When cold & warm cannot overtake each other (tie) | Stationery Front |
| Polar Easterlies; Prevailing Westerlies; Horse Latitudes; Trade Winds, Doldrums, Trade Winds, Horse Latitude, Prevailing Westerlies; polar Easterlies. | Global Winds |
| Cause by the rotating of the earth. A rotating body deflects | Coriolis Force |
| Any of the high speed, high altitude, air current that circle the earth in a westerly direction | Jet Stream |
| The cooling effect of wind and temperature combined. The higher the wind, the cooler it gets. | Wind Chill |
| The reflectiveness of a surface. Black observes all colors while white reflects all colors. | Albedo |
| A measure of the average kinetic energy (motion) of individual molecules and matter. 100 degree Celsius equals water boils 0 degrees celsius equals water freezers. | Temperature. |
| A devise that measures the heat from expanding and contracting liquids or coils. | Thermometer |
| What are the seasons are caused by the | Tilt of the earth axis 23.5 degrees |
| The continuous movement of water on, above, and below the surface of the earth. | The Water Cycle (Hydrologic Cycle) |
| Substance changes from a liquid state to a gas state (requires energy.) | Evaporation |
| Water vapor (gas) turns back to a liquid. (energy required/cold) ~ cloud formation | Condensation |
| Water that is so heavy that it falls as liquid/solid. | Precipitation. |
| Moisture condensed from atmosphere, esp at night, and deposited in the form of small drops upon any cool surface. | Dew |
| A visible body of very fine water droplets or ice particles suspended in the atmosphere at different altitudes. | Cloud |
| High altitude wispy clouds made of ice crystals. | Cirrus |
| White puffy clouds | Cumulus |
| Low lying layered clouds. Usually and grey and dull. | Stratus |
| Very tall dense, heavy, dark massive thunderstorms, hard showers, explosive top, great vertical development. | Cumulonimbus |
| The study of atmosphere that focuses on weather process and forecasting. | Meteorology |
| Thermometer; Anemometer; barometer; Rain gauge; satellites. | Weather tools. |
| Measures temperature | Thermometer |
| Identifies wind direction | Wind Vane |
| Measures air pressure | Barmometer |
| Measures rainfall | Rain gauge |
| Satellites | Provide a larger view of weather |
| A line drawn on a weather map or chart linking all points of equal or constant temperatures | Isotherm |
| The gradual warming of the earth caused by the green house effect. Man made emissions of green house gases. | Climate Change |
| A large, distinctive complex of plant communities, created and maintained by climate. | Biome |
| This biome is very wet with warm temperatures. This biome has the most plants and animals. | Tropical Rainforest. |
