Key words §3.4

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..

Water vapor (waterdamp): Invisible gas that forms when water evaporates.

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

Short hydrological cycle (korte waterkringloop): The process in which sea water evaporates and falls back into the sea through clouds and precipitation.

Long hydrological cycle (lange waterkringloop): The process in which sea water evaporates and flows back to the sea through clouds, precipitation, groundwater and rivers.

Glacier (gletsjer): Large bodies of ice on mountains as a result of snow falling on the mountains, which accumulates over time

Three types of rain

• Convectional rain (stijgingsregen)
• Frontal rain (Frontale regen)
• Relief rain (stuwingsregen)

Convectional rain (stijgingsregen)

Hot air rises. The higher, the colder. The water vapour in the rising air starts to condense. Which leads to rain we call convectional rainfall.

Where does rain occur?

Frontal rain (Frontale regen)

At temperate latitudes (gematigde breedte), warm air from low latitudes clash against cold air from polar regions, the warm air is forced to rise and frontal rain forms.

Relief rain (stuwingsregen)

When air is blown against mountains, the air is forced to rise, cools down and condenses. Leading to rainfall. This rain is called relief rainfall. On the other side of the mountains, it is dry, because the clouds have already emptied themselves of rain.
