Weather Patterns 1
| Question | Answer |
|---|---|
| water cycle | the cycle of processes by which water circulates between the earth's oceans |
| Precipitation | the falling to earth of any form of water (rain or snow or hail or sleet or mist) |
| Condensation | The cooling of water vapor to form liquid water droplets in the atmosphere to form clouds |
| Evaporation | The process by which molecules at the surface of a liquid absorb enough energy to change to a gas (water vapor). |
| transpiration | Evaporation of water from the leaves of a plant and enters the atmosphere as water vapor |
| run-off | rainfall that is not absorbed by soil and travels to the ocean |
| water vapor | water in the form of a gas in the atmosphere in the water cycle |
| sun | source of energy to drive evaporation in the water cycle |
| gravity | A force that pulls objects toward each other, triggers precipitation to fall and water to flow |
| clouds | a visible mass of condensed water vapor floating in the atmosphere |
| cirrus | Wispy, often high and made of ice crystals |
| cumulus | Fluffy, heaped clouds which start to build at lower levels |
| stratus | Clouds that form in flat layers and often cover much of the sky. |
| gas | phase of matter where molecules are spread apart and have high amounts of energy |
| liquid | phase of matter where molecules are close together and slide past each other |
| solid | phase on matter where molecules are packed together and vibrate, low amount of energy |
| excretion | animals give off extra water by urinating or sweating |
| hail | Frozen precipitation which falls during a thunderstorm |
| weather | State of the atmosphere at a specific time and place |
