Marano Weather #3
| Question | Answer |
|---|---|
| humidity | the amount of moisture (water vapor) in the aire |
| absolute humidity | number of grams of water vapor in one cubic meter of air |
| (Warm, cold) air can hold more moisture | warm |
| relative humidity | % of air full of water |
| When we reach 100% relative humidity, we have reached the _____. | dewpoint |
| The greater the humidity, the (lower, higher) the pressure | lower |
| The hight the temperature, the (lower, higher) the humidity | lower |
| air pressure measured with | hygrometer |
| hair hygrometer | hair lengthens or shortens depending on humidity |
| psychrometer | has two thermometers- dry bulb and wet bulb |
| evaporation is a (cooling, heating) process | cooling |
| The drier the air is the (more, less) evaporation will occur in the wet bulb. This evaporation causes the temperature on the wet bulb to (drop, rise) | more, drop |
| Dry air (more, less) evaporation= (greater, less) difference between the two thermometers. | more, greater |
| dew point | temperature when the air can no longer hold any more moisture and precipitation occurs |
| Cooler air holds (less, more) moisture | less |
| The closer the air temperature is to the Dew Point, the (lower, higher) the relative humidity is. | higher |
| water cycle | continuous movements of water from water sources into the air, onto and over the land, into the ground and back to the water sources |
| condensation | water vapor cools and changes back into liquid droplets |
| evaporation | liquid water changes back into water vapor |
| transpiration | plants release water vapor into the air through their leaves |
| precipitation | rain, snow, sleet, or hail faills fromt he clouds onto the Earth's surface |
| run off | water, usually from precipitation, that flows off the land and collects in rivers streams, and eventually the ocean |
