| Anemometer | A scientific tool used to measure wind speed |
| Atmosphere | The layer of gas surrounding a planet that is held in place by gravity. |
| Convection | Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, denser fluids |
| Coriolis Effect | The apparent deflection of moving air as seen by an observer on Earth, as a result of Earth's rotation. |
| Radiation | The transfer of energy by the movement of electromagnetic waves or subatomic particles. |
| Thermal Energy | The total Kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes. |
| Wind | A natural movement of air, sometimes with considerable force, from an area of low density and pressure. |
