| Question | Answer |
|---|---|
| Water cycle | The continuous movement of water on, above, and below the earth's surface. |
| Evaporation | When heat from the sun changes water from liquid to gas |
| Transpiration | The process when plants release water vapor through their leaves into the air. |
| Sublimation | When ice or snow changes directly into water vapor without becoming liquid first. |
| Condensation | When water vapor cools and changes back into liquid droplets, forming clouds. |
| Precipitation | Any form of water that falls from the sky, such as rain, snow, sleet or hail. |
| Air mass | A large body of air that has the same temperature and humidity throughout |
| Jet stream | A fast, narrow band of strong winds high in the atmosphere that moves weather systems around the earth. |
| Front | The boundary where two different air masses meet. |
| Thunderstorm | A storm with rain, thunder, lightning and sometimes strong winds. |
| Lightning | A bright flash of electricity that happens during a thunderstorm. |
| Thunder | The sound made by the rapid expansion of air after a lightning strike. |
| Hurricane | A large, rotating storm that forms over warm ocean water and has very strong winds. |
| Storm surge | A rise in ocean water level caused by the strong winds of a hurricane. |

| weather | the condition of the air at a certain place and time, such as temperature, rain, or wind. |
| humidity | the amount of water vapor in the air. |
| relative humidity | how full of water vapor the air is compared to how much it could hold at that temperature. |
| dew point | the temperature at which air becomes full of water vapor and dew ( tiny drops) begin to form. |
| air pressure | the force of the air pressing down on earth's surface. |
| wind | the movement of air caused by differences in air pressure. |
| visibility | how far you can see through the air. |
