Q5 — Synoptic link across topics (6 marks)

Question: Explain how knowledge of Global Hazards and Changing Climate can inform the choice of option in the booklet.

Mark scheme (6 marks, levelled):

• Level 1 (1–2): Generic links between topics; no booklet evidence.
• Level 2 (3–4): Synoptic links made; uses terminology (return period, magnitude–frequency, climate forcing, IPCC AR6).
• Level 3 (5–6): Detailed synoptic synthesis; explicit booklet evidence; references projected climate change impacts on hazard frequency (e.g. "+1.5 °C scenario raises 1-in-100-year flood to 1-in-30 in Fig. 9"); names a real-world analogue (Somerset Levels 2014; Boscastle 2004).
• Reward integration of physical processes and human vulnerability.
