Evaporation and transpiration move water upward
Liquid water becomes vapour from surfaces and plants.
Condensation forms droplets or ice
Cooling and changing humidity help water vapour form clouds.
Precipitation returns water
Rain, snow and other forms move water from the atmosphere to the surface.
Groundwater and runoff complete large loops
Water moves through soils, aquifers, rivers, lakes and oceans before cycling again.
