The Global Water Cycle

freshwater percentages

freshwater 2.5%

68.6% of freshwater in cryosphere

other 30.1% in groundwater

major stores of water

frozen water in cryosphere - 68.7%

liquid water in hydrosphere - 1%

water vapour in atmosphere - 0.2%

groundwater in lithosphere - 30.1%

what type of system is the water cycle

closed

processes where water is recycled

evaporation - sun evaporates surface water into vapour

condensation - water vapour condenses and precipitates

flows - water runs off surfaces into streams etc or beneath surface as groundflow

stores

water in atmosphere, surface stores, interception, ice and snow, seas and oceans, groundwater stores

aquifers

formed slowly over time

water infiltrates ground and collects in porous rock

interconnected pore spaces become saturated and form aquifer
