| precipitation | form of water that falls to earth through the atmosphere |
| condensation_nuclei | ***Microscopic atmospheric particles , which attract water droplets, & coalesce to form a raindrop |
| evaporation | Conversion of a liquid to the vapor state by the addition of latent heat |
| condensation | Condensation is the change of the physical state of matter from gaseous phase into liquid phase; reverse of evaporation |
| transpiration | passage of water through a plant from the roots through the vascular system to the atmosphere |
| runoff | excess water from rain, melt water, or other sources flows over the land. |
| aquifer | wet underground layer of water-bearing permeable rock |
| limestone | Limestone is a sedimentary rock composed largely of crystalline forms of calcium carbonate (CaCO 3). |
| acid_precipitation | ***Precipitation abnormally high in sulfuric & nitric acid content caused by atmospheric pollutants |
| sleet | Precipitation consisting of transparent frozen or partially frozen raindrops |
| fog | Fog is a cloud in contact with the ground |
| dew | Water droplets condensed from the air, usually at night, onto cool surfaces |
| hail | Hail is a form of solid precipitation which consists of balls or irregular lumps of ice |
| water_vapor | ***usually invisible gas phase of water |
| steam | visible form of vapor of any kind |
| crystalline | solid material whose atoms, molecules, or ions are arranged in a geometric pattern |
| infiltration | seeping of water into the ground |
