| Temperature | Degree of hotness or coldness of a substance |
| Ozone | Gas made up of three oxygen atoms |
| Troposphere | The lowest and most important atmospheric layer. |
| Stratosphere | Layer above the troposphere that is stratified. The top of which is the ozone layer. |
| Mesosphere | From 50-90km above the surface |
| Thermosphere | From 90km to the top of the atmosphere. Upper most layer. |
| 80% of the entire atmosphere | Troposphere |
| Lapse Rate | The vertical temperrature change in the atmosphere. |
| Inversion | Temperature increases with hieght. |
| Atmospheric Pressure | The force exerted by the atmospheric gaseson a unit area of surface. |
| 1 Kg mass | Mass of 1cubic meter of air at the surface. |
| 1013.25mb | Atmospheric pressure at sea level. |
| The millibar | Standard unit of atmos. pressure in meterology. |
| Density | Mass per unit volume |
| Daltons Law | each gas contributes to total pressure in proportion to its % of concentration. |
