Water Cycle
| Term | Definition |
|---|---|
| Water Cycle | Water continually cycles between the atmosphere (troposphere), land, and ocean via the water cycle. The following processes are propelled by sunlight and gravity |
| Precipitation | After condensation occurs (forming clouds), water droplets fall in various forms of |
| Precipitation | Temperature variations within clouds and/or within the region between the cloud and Earth allows for the various forms of |
| Forms of precipitation | rain, snow, freezing rain, sleet, or hail, |
| Evaporation/Transpiration | Water enters the atmosphere as water vapor through the processes of |
| Evaporation/Transpiration | Thermal energy from the sun causes water to |
| Condensation/Crystallization | As water vapor rises in the atmosphere it can turn into water droplets or ice crystals which results in cloud formation. |
| Condensation/Crystallization | of water vapor into water droplets or ice crystals must occur on a surface. |
| Condensation/Crystallization | Increases in thermal temperature causes water vapor to rise (evaporation) while a decrease in thermal temperature triggers condensation (clouds, dew, and frost). |
| Downhill Flow of Water on Land | If precipitation falls on land surfaces, it always attempts to move back toward sea level as |
| Downhill Flow of Water on Land | Precipitation is falling too fast for the water to sink into the ground. |
| Water | The amount of __________ on Earth has not changed over Earth’s history. Therefore, pollution can effect this cycle and the organisms that rely on it |
