The Water Cycle
Captions available
The idea
The water cycle moves water between atmosphere, land, and ocean through evaporation, transpiration, condensation, and precipitation, transporting the dissolved nutrients other cycles depend on.
In practice
Transpiration from forest vegetation returns water vapor to the atmosphere, feeding downwind precipitation.
Where people slip
The water cycle moves water, not nutrients directly — nutrients move as a secondary effect of water's movement through soil and runoff.
