| Precipitation | The process of water returning to the Earth’s surface in form of rain |
| Evaporation | Heat from the sun causing moisture to escape the surface of the ocean and rise |
| Condensation | Process where water droplets collect on small particles in the atmosphere as they cool |
| Cloud | Formed through the condenstaion of water droplets in the Bergeron Process |
| Water Cycle | The process where water is continually changed and reused |
| Condensation Nuclei | The small particles that clouds can form around and water droplets can collect on |
| Infiltration | The movement of water from the surface to underground |
| Groundwater | Water found underground and is part of the water table and other underground features |
| Permeability | The ability of a material to move water through it |
| Porosity | The amount of holes and open spaces in rock or soil |
| Geyser | A hot spring or fountain that ejects water from underground at intervals |
| Aquifer | Rock and soil that easily allows water to move through it and can hold much water |
| Artesian Well | A naturally occuring underground well that brings water above the water table |
| Water Table | The upper level of the grounds saturated zone where groundwater is found |
| Saturation | When an object gains the maximum amount of water it can hold at a temperature |
