Water cycle vocab
| Term | Definition |
|---|---|
| Water Cycle | the movement of water as it changes state around the earth |
| Evaporation | a change in state from a liquid to a gas (e.g. liquid water changing to water vapour) |
| Condensation | a change in state from a gas to a liquid (e.g. water vapour changing into liquid water) |
| Precipitation | water that has gathered in the clouds and falls to Earth as rain, hail, snow, or sleet |
| Collection | the gathering of precipitation and runoff in surface water receivers (e.g. lakes) |
| Sublimation | a change of tate from a solid into a gas (e.g. snow or ice changing into water vapour without passing through the liquid phase) |
| Groundwater | water that sinks into the ground – usually only seen to be water that has percolated down into the saturated zone |
| Aquatard | an impervious layer of clay, silt, or rock through which water cannot move quickly |
| Aquaifer | an underground zone of rock or soil that contains and yields water |
| Saturated zone | the area beneath the water table where water fills the spaces in the gravel, sand, silt, or rock |
| Water table | the upper boundary of the saturated zone – it rises as a result of rainfall and falls as a result of evaporation and human use |
| Percolation | the process of seeping through porous material |
| Capillary action | the upward movement of water through soil due to the attraction of water molecules to soil particles |
