| Condensation | water vapor becoming water |
| Evaporation | water turning into water vapor |
| Run off | water collecting above ground due to saturation |
| saturation | the ground absorbing all the water it can |
| Continent | body of land surrounded by water |
| Cloud | condensed water vapor after cooling/collects on condensation nuclei |
| precipitation | water returning to earth |
| ground water | water located under the surface of the earth |
| Condensation nuclei | dust, dirt, air pollution, car exhaust,ashes, sand |
| Ice | solid form of H2O locked in polar regions |
| Lakes and rivers | examples of run off |
| Mudslides/Landslides | results of saturation |
| Wells | how we get groundwater |
| percolation | water traveling through dirt and sand |
