| Question | Answer |
|---|---|
| electromagnectic waves | Waves that transfer electric and magnetic energy through the vacuum of space. |
| radiation | The direct transfer ofenergy by electromagnetic waves. |
| infrared radiation | Electromagnetic waves with wavelength that are longer than visible light but shorter than microwaves. |
| ultraviolet radiation | Electromagnetic waves with wavelengths that are shorter than visible light but longer than x-rays. |
| scattering | Reflection of light in all directions. |
| greenhouse effect | Gases in the atmosphere that trap energy. |
| temperature | A measure of how hot or cold an object is compared to a refrench point. |
| thermal energy | The total energy of motion in the particles of a substance |
| thermometer | An instrument used to measure tempature |
| heat | The transfer of thermal energy from one object to another because of a diffrence in tempature. |
| conduction | The direct transfer of thermal energy from one subtance to another by direct contact. |
| convection | The transfer of thermal energy by the movement of a fluid |
| convection currents | The circulation of a fluid as it alternately heats up and cools down. |
| wind | the horizontal movement of air from an area of high pressure to an area of lower pressure. |
| anemometer | An instrument used to measure wind speed. |
| wind-chill factor | A measure of cooling combining tempature and wind speed. |
| local winds | Winds that blow over short distances |
| sea breeze | The flow of cooler air from over an ocean or lake toward land. |
| land breeze | The flow of air from land to a body of water. |
| global winds | Winds that blow steadily from specific directions over long distances. |
| Coriolis effect | The change that Earth's rotation causes in the motions of objects and that explains how winds curve. |
| jet stream | Bands of high-speed winds about 10 kilometers above Earth's surface. |
