| groundwater | collects underground in an aquifer; supplies wells and springs |
| water cycle | describes how water moves around the Earth by the processes opf evaporation, condensation, precipitation and transpiration |
| evaporation | process by which water particles gain energy usually through the sun's heat and enters its gaseous state (water vapor) |
| transpiration | process in which plants open tiny pores on their leaves to gain carbon dioxide but lose water |
| condensation | process by which a substance in its gaseous state loses energy and enters its liquid state |
| precipitation | water vapor in the atmosphere falling back to Earth in the form of rain, hail, sleet, or snow |
| surface water | water contained in places such as lakes, ponds, rivers, streams, and reservoirs |
| surface runoff | water that flows over land until it reaches lakes, rivers, or other areas |
| aquifer | underground area of sediment and rocks where groundwater collects |
| watershed | an area of land that catches all rain and snow and collects it in one place like a river |
| collection | When the ground takes in water (usually from snow or rain) |
| clouds | are made up of water particles and ice particles |
