- W&CC p.p 1
- water cycle
- closed system
- water is not lost or gained from space
- components/stalls such as trees built up areas and soil
- flows/transfers include through flow and groundwater flow
- components/stalls such as trees built up areas and soil
- water is not lost or gained from space
- closed system
- 'spaceship' earth
- expresses the concern over the use of limited resources available on earth and encouraging everyone on it to act as a harmonious crew working towards the greater good
- common characteristics of a system
- structure that lies within a boundary
- generalisation of reality removing the incidental details that obscures fundamental relationship
- functions by having inputs ad outputs of material
- generalisation of reality removing the incidental details that obscures fundamental relationship
- structure that lies within a boundary
- stores/components
- flows/transfers
- elements
- attributes
- relationships
- system
- interrelated parts that work together by some driving process
- helps us to understand the physical and human world around us
- interrelated parts that work together by some driving process
- 4 major subsystems
- atmosphere
- lithosphere
- hydrosphere
- biosphere
- CASCADING SYSTEM
- biosphere
- hydrosphere
- lithosphere
- atmosphere
- Dynamic equilibrium
- balance between inputs and outputs
- can be upset when one of the elements in the system changes
- FEEDBACK
- natural and human change can often upset the dynamic equilibrium of the water cycle
- FEEDBACK
- can be upset when one of the elements in the system changes
- balance between inputs and outputs
- models
- earth is complex --> simplify so relationship between components could be understood
- DTM and the water cycle
- earth is complex --> simplify so relationship between components could be understood
- dynamic equilibrium
- closed system, open system, isolated system
- inputs and outputs
- water cycle
