| Electromagnetic Waves | Waves that can transfer electric and magnetic energy through the vacuum of space. |
| Radiation | The transfer of energy by electromagnetic waves. |
| Infrared Radiation | Electromagnetic waves with wavelengths 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 | How hot or cold something is; a measure of the average energy of motion of the particles of a substance. |
| Thermal Energy | The total energy of all the particles of an object. |
| Thermometer | An instrument used to measure temperatures. |
| Heat | The transfer of thermal energy from one object to another because of difference in temperature. |
| Convection | The transfer of thermal energy by the movement of a fluid. |
| Conduction | The transfer of thermal energy from one particle of matter to another. |
| Convection Current | The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another. |
| 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 temperature 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 effect of Earth’s rotation on the direction of winds and currents. |
| Latitude | The distance in degrees north or south of the equator. |
