What is weather? | the atmospheric conditions, along with short-term changes, of a certain place at a certain time. |
What is air pressure? | pressure that a column of air exerts on the air, or surface below. |
What is relative humidity? | the amount of water vapor present in the air compared ot the maximum amount of water vapor the air could contain at that temperature. |
What is humidity? | the amount of water vapor in the air. |
What is dew point? | the temperature at which air is fully saturated because of decreasing temperatures while holding the amount of moisture constant. |
What is precipitation? | water, in liquid or solid form, that falls from the atmosphere. |
What is water cycle? | the series of natural processes in which water continually moves among oceans, land, and the atmosphere. |
What is the average kinetic energy of molecules in the air? | air temperature |
What is barometric pressure? | another name for air pressure |
When air moves from high and low ares of high and low pressure, what is this called? | wind |
What is used to measure relative humidity? | a psychrometer |
What happens when the air gets saturated with water vapor? | the water vapor will condense and form water droplets, called rain. |
What happens when the temperature decreases? | the air holds less moisture |

When does water vapor enter the atmosphere? | when water is heated and evaporates at eh ocean's surface. |
How does this cycle keep going? | clouds produce precipitation, which falls to Earth's surface and later evaporates. |
