IB ESS SL 1.2.11 Tipping Points Questions

Practise SL questions on tipping points by identifying destabilising thresholds, tracing positive-feedback amplification and explaining shifts to new stable states.

Exam points

Identify the threshold at which a small additional change destabilises a system.
Explain how positive feedback can push a system beyond a tipping point into an alternative stable state.
Use an aquatic eutrophication example to trace amplification toward a new equilibrium.
Distinguish stabilising equilibrium from a tipping-point shift caused by positive feedback.
