Fresh water (zoet water): Water with a low concentration of dissolved salt. Drinking water is fresh water too.
Salt water (zout water): Water with a high concentration of dissolved salt. Sea water for example
Precipitation (neerslag): The different ways water falls back down to earth. For instance as rain, snow or hail.
Evaporation (verdamping): The process of water in liquid form turning into water in gaseous (gas) form..
Condensation (condensatie): The proces of a gas turning into a liquid. When watervapour cools it condenses into tiny drops of water and ice crystals. This is what we call clouds.
Infiltration (infiltratie): process by which water enters the soil (bodem)
Hydrological cycle (waterkringloop): The process by which seawater returns to the sea through evaporation and precipitation, and through groundwater and rivers
Watervapour (waterdamp): The gaseous state of water
Surface water (oppervlaktewater): water that is visible, such as lakes, rivers and seas
Ground water (grondwater): Water that is no longer visible, because it has infiltrated into the rock, and is now underground.
Glacier (gletsjer): Large bodies of ice on mountains as a result of snow falling on the mountains, which accumulates over time
Landice (landijs): Masses of ice which are on land
