water cycle,  | The repeated movement of water between the atmosphere and Earth's surface |
| evaporation | liquid water to water vapor (heat added) |
| transpiration | evaporation from plants |
| condensation | gas (water vapor) becomes a liquid (water) |
| condensation nuclei | tiny particles providing surface on which water may condense to form clouds |
| precipitation | rain, snow, sleet, hail |
| infiltration | precipitation soaks into the ground |
| groundwater | water found in the spaces between soil particles and cracks in rocks underground |
| runoff | precipitation that flows over land to surface streams, rivers, and lakes. |
| sun | provides energy (powers the water cycle) |
| evaporation | happens when heat is added to a liquid |
| clouds | form when water vapor in the air condenses to form liquid water or ice crystals |
| condensation | happens when heat is removed from a gas (during cooling) |
