B&W Weather Factors
| Question | Answer |
|---|---|
| Transverse waves that transfer electrical and magnetic energy. | ELECTROMAGNETIC WAVES |
| The direct transfer of energy by electromagnetic waves. | RADIATION |
| Electromagnetic waves with wavelengths that are longer than visible light but are shorter than microwaves. | INFRARED RADIATION |
| Electromagnetic waves with wavelengths that are shorter than visible light but longer than X-rays. | ULTRAVIOLET RADIATION |
| Reflection of light in all directions. | SCATTERING |
| The process by which heat is trapped in the atmosphere by gases that form a "blanket" around Earth. | GREENHOUSE EFFECT |
| A measure of how hot or cold an object is compared to a reference point. | TEMPERATURE |
| The total energy of motion in the particles of a substance. | THERMAL ENERGY |
| An instrument used to measure temperature. | THERMOMETER |
| The transfer of thermal energy from one object to another because of a difference in temperature. | HEAT |
| The direct transfer of thermal energy from one substance to another that it is touching. | CONDUCTION |
| The transfer of thermal energy by the movement of a fluid. | CONVECTION |
| The circulation of a fluid as it alternately heats up and cools down. | CONVECTION CURRENTS |
| The horizontal movement of air from an area of high pressure to an area of lower pressure. | WIND |
| An instrument used to measure wind speed. | ANEMOMETER |
| A measure of cooling combining temperature and wind speed. | WIND-CHILL FACTOR |
| Winds that blow over short distances; caused by the unequal heating of Earth's surface in a small area. | LOCAL WINDS |
| The flow of air from land to a body of water. | LAND BREEZE |
| Winds that blow steadily from specific directions over long distances. | GLOBAL WINDS |
| The change that Earth's rotation causes in the motion of objects and that explains how winds curve. | CORIOLIS EFFECT |
| The distance from the equator, measured in degrees. | LATITUDE |
| Bands of high-speed winds about 10 km above Earth's surface. | JET STREAM |
| The flow of cooler air from over an ocean or lake toward land. | SEA BREEZE |
| The continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation. | WATER CYCLE |
| The process by which water molecules in liquid water escape into the air as water vapor. | EVAPORATION |
| The amount of water vapor in a given volume of air. | HUMIDITY |
| The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature. | RELATIVE HUMIDITY |
| Instrument used to measure relative humidity. | PSYCHROMETER |
| The process by which molecules of water vapor in the air become liquid water. | CONDENSATION |
| The temperature at which condensation begins. | DEW POINT |
| Wispy, feathery clouds of ice crystals that form at high levels. | CIRRUS |
| Fluffy, white clouds, usually with flat bottoms, that look like rounded piles of cotton. | CUMULUS |
| Clouds that form flat layers and often cover much of the sky. | STRATUS |
| Any form of water that falls from clouds and reaches Earth's surface. | PRECIPITATION |
| Long periods of low precipitation. | DROUGHT |
| Method used to try to produce rain by sprinkling chemicals into clouds. | CLOUD SEEDING |
| An instrument used to measure precipitation. | RAIN GAUGE |
