IB ESS 4.1.13 (HL) Upwellings
Practise explaining how upwellings move cold, nutrient-rich water to the surface and affect productivity in oceans or lakes.
How this is tested
- apply an upwelling diagram to explain increased nutrients and surface productivity
- link seasonal lake cycles or ENSO changes to shifts in nutrient-rich water movement
