Rivers: The water cycle Aims: To become familiar with the water cycle as a system To be able to use the words: PRECIPITATION, CONDENSATION and EVAPORATION Skills: Labelling diagrams
3
A System? INPUTS PROCESSES OUTPUTS Closed system – where inputs and outputs remain in the system. Nothing outside the system can contribute to it. Open System – where inputs and outputs come from outside the system. Things outside the system can contribute to it.
