| Term | Definition |
|---|---|
| Air Pressure | A force exerted by moving air molecules. |
| convection | The method of heat transfer through a fluid due to density differences. |
| conduction | A method of heat transfer through direct contact. (must be touching) |
| radiation | Energy that comes from a source and travels through some material or through space. Light, heat and sound are types of radiation. |
| wind | The horizontal movement of air caused by differences in air pressure. It moves from higher pressure to lower pressure areas. |
| weather | The condition of Earth's atmosphere at a particular time and place. |
| climate | The characteristic weather conditions in an area over a long period of time. |
| Coriolis Effect | The influence of Earth's rotation on objects that move over earth. This causes currents to move clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere. |
| Jet Stream | A narrow, variable band of very strong, predominantly westerly air currents encircling the globe several miles above the earth. |
| Earth's Axis | the imaginary line which goes through the north and south poles and around which Earth spins. |
| Orbit | The curved path of a celestial object or spacecraft around a star, planet, or moon |
| Rotation | The action of rotating around an axis or center |
| Absorption | The process or action by which one thing absorbs or is absorbed by another |
| Air Mass | A body of air with horizontally uniform levels of temperature, humidity, and pressure. |
| Weather fronts | a boundary separating two masses of air of different densities |
