| Question | Answer |
|---|---|
| What is measured in inches of mercury? | air pressure |
| When water freezes and strong updrafts continually carry it to the tops of clouds to collect and refreeze until too heavy and then falls to the ground is callled... | hail |
| What has the highest humidity? | warm saturated air |
| When water passes through a cold layer and freezes AFTER hitting the ground it is called... | freezing rain |
| If an object's mass increases, but its volume stays the same, then this will increase... | density |
| Clouds form when this condenses in the air... | water vapor |
| The dew point is when the air reaches 100% of what and condensation takes place? | relative humidity |
| As this increases, air pressure decreases. | altitude |
| Sleet occurs when water passes through a cold layer and freezes BEFORE or AFTER hitting the ground? | before |
| Water droplets make a ... | cloud |
| A barometer measures... | air pressure |
| As the temperature decreases, the capacity decreases, causing the relative humidity to... | increase |
| Sleet differs from this because it starts as rain and freezes in the air... | snow |
| Increase in temperature increases air's ability to hold this... | water vapor |
| If a given mass of air is holding 50 liters of water, and is capable of holding 100 liters at its current temperature, then the relative humidity of the air mass is what? | 50% |
