amazon.co.ukG1: Water and Carbon Cycles, Hazards and Global Governance
Hydrological flows, carbon stores, feedback loops, plate tectonics and hazard management, globalization, global governance.
📋 Key Definitions and Core Concepts
Carbon Sink: A natural or artificial reservoir that absorbs and stores more carbon than it releases (e.g. tropical rainforests, oceans).
Hazard Vulnerability: The conditions determined by physical, social, economic, and environmental factors which increase the susceptibility of a community to hazard impacts.
🔍 Key Principles & Specification Requirements
- Positive feedback (e.g. arctic permafrost thaw releases CH₄ accelerating warming); negative feedback (e.g. higher CO₂ stimulates photosynthesis).
- Tectonic hazards: destructive, constructive, conservative plate margins; hazard management via Park model and hazard management cycle.
- Globalisation mechanisms: TNCs, trade blocs (EU, USMCA), containerisation, WTO liberalisation.
💡 Worked Example Question
Exam-Style Question
Question:
Explain how deforestation impacts both the local hydrological cycle and the global carbon cycle.
Model Solution & Mark Scheme:
Hydrological: Reduces interception and evapotranspiration; increases overland surface runoff and soil erosion; leads to flashier river discharge hydrographs and local drought. Carbon: Burning/decay of trees releases stored carbon as CO₂; removes an active terrestrial carbon sink; accelerates atmospheric greenhouse gas accumulation and global radiative forcing.
