7.1 HW: Hart
| Question | Answer |
|---|---|
| Weather | Is the atmospheric conditions, along with short-term changes, of a certain place at a certain time |
| Air Pressure | The pressure that a column of air exerts on the air, or surface, below it |
| Humidity | The amount of water vapor in the air |
| Relative Humidity | The amount of water vapor present in the air compared to the maximum amount of water vapor the air could contain at the temperature |
| Dew Point | Is the temperature at which air is fully saturated because of decreasing temperatures while holding the amount of moisture constant |
| Precipitation | Is water, in liquid or solid form, that falls from the atmosphere |
| Water Cycle | Is the series of natural processes in which water continually moves among oceans, land, and the atmosphere |
| What are two variables to describe weather | Temperature and Rainfall |
| The measure of the average kinetic energy of molecules in the air | Air temperature |
| What term is used by a meteorologist during a weather forecast to refer air pressure | Barometric pressure |
| As air moves from areas of high pressure to areas of low pressure which creates _____ | Wind |
| Clouds are ______ or ______ suspended in the atmosphere | Water droplets or ice crystals |
| _____ can have different shapes and be present at different altitudes within the atmosphere | Clouds |
| A cloud that forms near Earth's surface | Fog |
| Fog suspension of _____ or _____ close to or at Earth's surface | Water droplets or ice crystals |
| Fog reduces _____, the distance a person can see into the atmosphere | Visibility |
| ______ in the clouds form around small solid particles in the atmosphere | Droplets |
| These particles might be ____, _____, or _____ | Dust, salt, or smoke |
| What are examples of precipitation | Rain, snow, sleet, and hail |
| _____ is precipitation that reaches Earth's surface as droplets of water | Rain |
| _____ is an important process in the water cycle | Precipitation |
| _____ and _____ are phase changes that are also important to the water cycle | Evaporation and condensation |
| _____ help reflect radiation | Clouds |
| We observe that clouds move, we recognize that ___ and ___ are transported from one location to another | Water and thermal energy |
| ___, ____, ___, and ___ help particles change from one thing to another when the clouds release the thermal energy | Condensation, Freezing, Evaporation, and Melting |
| Most sunlight passes through the atmosphere and warms Earth's surface but is radiation to the troposphere which causes ___ | Weather |
| _____ helped built ancient Earth's atmosphere when it did not have enough oxygen to support life | Water Vapor |
