| 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 high density and pressure to an area of low density and pressure. |
