7.1 HW: Hart

Weather Is 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 it
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 the temperature
Dew Point Is the temperature at which air is fully saturated because of decreasing temperatures while holding the amount of moisture constant
Precipitation Is water, in liquid or solid form, that falls from the atmosphere
Water Cycle Is the series of natural processes in which water continually moves among oceans, land, and the atmosphere
What are two variables to describe weather Temperature and Rainfall
The measure of the average kinetic energy of molecules in the air Air temperature
What term is used by a meteorologist during a weather forecast to refer air pressure Barometric pressure
