7.1 HW: Harbaugh

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
