Rivers: The global hydrological cycle keyterms Flashcards
Biosphere?
The store of water in living organisms such as trees.
Desalination?
Removal of salt from sea water.
Flow?
The movement of water from one store to another.
Evaporation?
Change in state from liquid to vapour due to heating.
Transpiration?
The transfer of water from plants to air as water vapour.
Surface run-off?
Flow of water over the land.
Infiltration?
Rain enters into the soil.
Throughflow?
Movement of water through soil horizontally and vertically.
Percolation?
The downward movement of water into the soil layer due to gravity.
Precipitation?
Water falls to Earth as rain, hail, sleet and snow.
Interception?
Water caught on leaves as vegetation.
Impermeable?
Rocks that don’t let the water pass through.
Water table?
The level of water under the ground.
Condensation?
Change in state from vapour to liquid due to cooling.
Aquifer?
A rock such as chalk that can hold water.
Evapotranspiration?
Transfer of water from the land surface to the air as vapour.
Permeable?
A rock that lets water seep through it.
Channel flow?
Water flowing in a river or stream.
Latent heat?
The energy needed to change the state of water.
Sublimation?
Solid to gas without going through the liquid stage.
