| temperature | a measure of how hot or cold an object is compared to a reference point |
| thermal energy | the total energy of motion in the given particles of a substance |
| thermometer | an instrument used to measure temperature |
| heat | the transfer of thermal energy from one object to another because of a difference in temperature |
| conduction | the direct transfer of thermal energy from one substance to another that is touching |
| convection | the transfer of thermal energy by the movement of a fluid |
| convection currents | the circulation of a fluid as it alternately heats up or 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 the 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 change that Earth's rotation causes in the motion of objects and that explains how winds curve |
| latitude | distance from the equator, measured in degrees |
| jet stream | bands of high-speed winds about 10 kilometers above the Earth's surface |
