| Troposphere | Layer of air closest to earth |
| Stratosphere | layer of air made up of ozone |
| Mesophere | the layer above the stratosphere |
| Thermosphere | layer of air that increases in temperature |
| Exosphere | outermost layer of the earth's atmosphere |
| Radiation | transfer of energy through space by visible light, and other electromagnetic waves |
| Conduction | Transfer of energy that occurs when the molecules collide |
| Convection | Transfer of energy by the flow of a heated substance |
| Temperature | Measurement of how rapidly or slowly molecules move around |
| Heat | Transfer of energy that occurs due to a difference in temperature between substances |
