- Water and Carbon Cycles - 1
- Natural Systems
- Systems
- inputs
- outputs
- stores
- flows
- boundaries
- Open Systems
- energy and matter
- enter and leave
- e.g. drainage basin
- Closed Systems
- matter - cycle
- energy - enter and leave
- e.g. carbon cycle
- Feedback
- positive feedback
- amplify change
- negative impact
- negative feedback
- positive impact
- counteract change
- inupt = output: equilibrium
- varied inputs + outputs: dynamic equilibrium
- positive feedback
- Subsystems
- cryosphere
- lithosphere
- biosphere
- hydrosphere
- atmosphere
- Systems
- The Water Cycle
- Forms
- solid
- liquid
- gas
- Fresh Water
- cryosphere
- 69%
- groundwater
- 30%
- freshwater - liquid
- 0.3%
- water vapour
- 0.04%
- - 3% (total)
- cryosphere
- Global Hydrological Cycle
- continuous cycles
- closed system
- no inputs
- no outputs
- Flows
- evaporation
- liquid -> gas
- magnitude
- varies: location / season
- energy - solar radiation
- condensation
- gas -> liquid
- energy low
- magnitude
- amount of water vapour in atmosphere
- Precipitation
- water vapour condenses
- main flow
- warm air = cool
- evaporation
- Forms
- Drainage Basins
- Natural Systems
- open cycle
- boundary - watershed
- input
- precipitation
- output
- river discharge
- Defenition
- area surrounding river where rain flows into that river
- Inputs
- precipitation
- rain
- hail
- snow
- precipitation
- Stores
- interception
- vegetation
- surface
- soil
- Flows
- infiltration
- overland flow
- throughfall
- percolation
- channel flow
- Outputs
- evaporation
- transpiration
- evapo - transpiration
- river discharge
- Water Balance
- difference between inputs and outputs
- wet season
- water surplus
- dry season
- water defecit
- water recharged in wet season
- Natural Systems
- Runoff Variations
- Hydrographs
- river discharge over time
- river discharge - cubic metres, m3
- Shape of Hydrograph
- factors
- size of drainage basin
- shape of drainage basin
- steepness
- rock type
- soil type
- factors
- Physical Factors
- seasonal changes
- vegetation
- storms
- precipitation
- Human Factors
