Question | Answer |
---|---|
1. weather | the atmospheric conditions, along with short-term changes, of a certain place at a certain time. |
2. air pressure | the pressure that a column of air exerts on the air, or surface, below it is air pressure. |
3. relative humidity | the amount of water vapor present in the air compared to the maximum amount of water vapor the air could contain at that temperature. |
4. dew point | the temperature at which air is fully saturated because of decreasing temperatures while holding the amount of moisture constant. |
5. precipitation | water, in liquid or solid form, that falls from the atmosphere. |
6. water cycle | the series of natural processes in which water continually moves among oceans, land, and and the atmosphere. |
1. what are two variables used to describe weather? | temperature and rainfall |
2. what are some of the variety of atmospheric conditions? | temperature, air pressure, wind speed and direction, humidity, cloud coverage, and precipitation |
3. what is the average kinetic energy of molecules in the air? | air temperature |
4. if air pressure decreases, what happens to the altitude? | increases |
5. what does barometric pressure mean? | air pressure |
6. what happens when areas of high pressure air moves to areas of low pressure? | wind |
7. when the humidity is high, is there more or less water vapor in the air? | more |
8. can warm air contain more or less water vapor than cold air? | more |
9. when the air near the ground becomes saturated, the water vapor condenses into what? | liquid |
10. when the temperature decreases, the air can hold more or less moisture? | less |
11. what is a cloud that forms near earth's surface? | fog |
12. do clouds absorb or reflect some of earth's incoming radiation? | reflect |
13. what can droplets in clouds form around in the atmosphere? | dust, salt, or smoke |
14. other than precipitation, what are two other important processes in the water cycle? | evaporation and condensation |
15. water vapor cools and rises in the atmosphere and condenses back into what? | liquid |
1. what are types of precipitation that are solid? (7.1) | sleet, hail, and snow |
2. what is precipitation in liquid form? (7.1) | rain |
3. what are the types of acid precipitation? (6.4) | acid rain, snow, and fog |
4. what is water vapor? (6.1) | water in gaseous form |
5. what is the difference between acid precipitation and normal rainwater? (6.4) | acid precipitation has a lower pH than that of normal rainwater |
