Heat and Winds
| Question | Answer |
|---|---|
| The average amount of energy of motion of each particle of a substance. | Temperature |
| Air temperature is usually measured with a __________________. | Thermometer |
| The total energy of motion in the particles of a substance. | Thermal energy |
| Heat can be transferred in one of these three ways... | Radiation, Conduction, Convection |
| The transfer of thermal energy from a hotter object to a cooler one. | Heat |
| The direct transfer of energy by electromagnetic waves. | Radiation |
| The direct transfer of heat from one substance to another substance that it is touching. | Conduction |
| The transfer of heat by the movement of a fluid. | Convection |
| The upward movement of warm air and the downward movement of cool air. | Convection currents |
| The horizontal movement of air from an area of high pressure to an area of lower pressure. | Wind |
| __________________ are caused by differences in air pressure. | Winds |
| Wind speed is measured with a(n) __________________. | Anemometer |
| These are winds that blow over short distances. | Local winds |
| Local winds are caused by the ________________ heating of Earth's surface within a small area. | Unequal |
| A __________________ is a local wind that blows from an ocean or lake. | Sea |
| A __________________ is a local wind that blows from land to a body of water. | Land |
| These are winds that blow steadily from specific directions over long distances. | Global winds |
| How are local winds and global winds similar and different? | They both are created by unequal heating of Earth's surface, but global winds occur over a large area. |
| The way Earth's rotation makes winds curve is called the _______________________. | Coriolis effect |
| These global winds play an important part in the weather of the United States. The blow from west to east. | Prevailing westerlies |
| The __________________ occur in an area near the equator with little or no wind. | Doldrums |
| The __________________ are bands of high-speed winds that are about 10 kilometers above Earth's surface. | Jet streams |
| Warm air is _____________ dense than cold air. | Less |
| Cold air is _____________ dense than warm air. | More |
| Warmer air in an area creates an area of ____________ pressure. | Low |
| Cooler air in an area creates an area of ____________ pressure. | High |
| Within the troposphere, heat is transferred mostly by _____________. | Convection |
| Is the air along the equator an area of high or low pressure? | Low pressure |
| Winds blow from an area of ____________ pressure to an an area of ____________ pressure. | High, low (or lower) |
