| Wetland | land or areas that are flooded all or part of the year (like a swamp) |
| Precipitation | several forms of liquid water or ice that fall from the atmosphere down to earth (snow, rain, sleet, or hail) |
| Seepage | when water comes up from the ground and forms a spring |
| Ocean | the largest water reservoir on earth (97.2%) |
| Spring or Stream | a flow of water in a narrow path, leading to a river, lake, or ocean |
| Sun | the source of energy that drives the water cycle |
| Infiltration | the downward movement of water through the ground |
| Aquifer | an underground layer of rock that holds water |
| Condensation | when water vapor turns into liquid water |
| Water Vapor | the gas form of water that is invisible in the air |
| River | a large stream of water that flows into a lake or ocean |
| Heat Energy Released | heat or energy is given off to the environment during freezing, condensation, or deposition |
| Frost | when ice forms from water vapor (deposition)(this usually occurs on plants) |
| Transpiration | release of water vapor through the leaves of a plant into the atmosphere |
| Run-off | water that runs into other bodies of water |
| Glacier | a huge mass of ice formed by crystallized snow (second largest water reservoir on Earth) |
| Heat Energy Absobed | heat or energy is needed for a phase change such as melting, evaporation, or sublimation |
| Deposition | phase change from water vapor (gas) to ice (solid) |
| Sublimation | phase change from ice (solid) to water vapor (gas) |
| Evaporation | liquid water changes to an invisible gas called water vapor |
