| weather | state of the atmosphere at a given time or place |
| meteorology | the study of the atmosphere |
| humidity | the amount of moisture in the air |
| windchill | temperature the body feels due to air temperature and wind effects |
| ozone | oxygen molecule made of 3 oxygen atoms,important to absorve ultraviolet radiation |
| radiation | movement of heat trough electromagnetic waves |
| conduction | movement of heat by coming in contact with hotter objects |
| convection | moving of heat in currents of gas or liquids |
| greenhouse effect | trapping of heat from the sun by carbon dioxide in the atmosphere |
| evaporation | the change from liquid water to liquid vapor |
| condensation | the change from water vapor to liquid water |
| specific humidity | the amount of water vapor actually present in the air |
| relative humidity | compares the actual amount of water in the air with the maximum amount of vapor the air can hold |
| hygrometer | instrument used to measure relative humidity |
| saturation | how much moisture the air can hold |
