Hydrologic cycle, Reservoirs and fluxes

What are the 4 major reservoirs?

1. Atmosphere 2. ocean 3. surface water 4. ground water

What are the major 6 fluxes?

1. surface --> atmosphere 2. ocean --> atmosphere 3. atmosphere --> surface/ocean 4. surface --> groundwater 5. groundwater --> surface 6. groundwater--> ocean

How is the hydrologic cycle presented?

Reservoirs and fluxes

What does the hydrologic cycle refer to?

The storage and movement of water in atmosphere, lithosphere, biosphere and hydrosphere

T/F Long residence times act to moderate changes to the water and climate system

True

how long is water stored in a reservoir?

either briefly or a long time

ocean --> atmosphere = what?

evaporation

surface --> atmosphere = what?

evaporation/transportation

what is a flux?

exchanges of water between different reservoirs

how are fluxes given?

given as rates

groundwater --> surface = what?

groundwater recharge of rivers, springs

surface --> groundwater = what?

infiltration and percolation

What is a reservoir?

places where water is being stored

atmosphere --> surface/ocean = what?

precipitation

groundwater--> ocean = what?

subsurface flow

what is residence time?

the average time an individual water molecule stays in a particular reservoir
