A system of water flows and storages
Storages (hydrological cycle)
organisms
oceans
groundwater (aquifers)
lakes
soil
rivers
atmosphere
glaciers and ice caps
Flows
Evapotranspiration
sublimination
evaporation
condensation
advection (wind-blown movement)
precipitation
melting
freezing
flooding
surface run-off
infiltration
percolation
stream-flow /currents
May be disrupted by human activity
agriculture
deforestation
urbanisation
Solar radiation
drives hydrological cycle
Fresh water
2.6% of Earth's water storages
Ocean circulation system
driven by differences in temp. & salinity
ocean conveyer belt
distributes hear around the world
affects climate
