Question | Answer |
---|---|
Weather | the atmospheric conditions, along with short-term changes, of a certain place at a certain time |
Air Pressure | the pressure that a column of air exerts on the air, or surface, below |
Humidity | the amount of water vapor in the air |
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 |
Dew Point | The temperature at which air is fully saturated because of decreasing temperatures while holding the amount of moisture constant |
Precipitation | Water , in liquid form or solid form, that falls from the atmosphere |
Water Cycle | the series of natural processes in which water continually moves among oceans, land, and the atmosphere |
