The Gobal Hydrologicol Cycle Flashcards
The global hydrological cycle is an example of a closed system which is driven by solar energy.
Yes, it does not have any inputs or outputs. The water can exist in different states for example the cryosphere in a solid form of snow and ice
Store
Resoviour where water is held, e.g Ocean
Fluxes
Rate if flow between the stores
Processes
The physical mechanisms driving fixes between stores
Cryosphere
Areas where water is from into snow or ice.
Precipitation
The movement if water in any form from the atmosphere to the ground
Evaporation
Change of liquid to water vapour
The major impact of fluxes
The major fluxes are shown and driven by precipitation and evaporation, these have been quantified
Residence times
The average time a water molecule will spend in a resoviour or store
Storage of water in hydrological cycle
On land the water is stored in rivers, streams and and lakes, this is known as blue water. Water stored as soil in vegetation is known as green water.
