IB ESS 4.1.2 Hydrological cycle
Practise using hydrological-cycle diagrams to identify water stores and flows, especially inputs and outputs for named lakes and catchments.
How this is tested
- label a water-system diagram with inputs and outputs
- outline how urbanisation reduces stores by lowering infiltration or evapotranspiration
