Topic Synopsis
This section explores the nature of natural hazards, focusing on tectonic and weather hazards, their causes, impacts, and management, as well as the evidence for and management of climate change.
Key Concepts & Core Principles
- Natural Hazards: Understanding the causes, characteristics, and impacts of tectonic hazards (earthquakes, volcanoes), tropical storms, and extreme weather events (e.g., droughts, floods) globally and in the UK.
- Ecosystems: The interdependence of living organisms and their physical environment, focusing on global biomes like tropical rainforests and hot deserts, including their characteristics, threats, and management.
- Physical Landscapes in the UK: Detailed study of coastal and river landscapes, including the processes (erosion, transport, deposition) that shape them, and the various hard and soft engineering strategies used for their management.
- Climate Change: The evidence for climate change, its natural and human causes, a range of environmental and social impacts, and the global and local responses to mitigation and adaptation.
- Interdependence & Management: Recognising how different elements of the physical environment are interconnected and how humans attempt to manage these systems sustainably to reduce risks and exploit opportunities.
Exam Tips & Revision Strategies
- Ensure you have a named case study for an earthquake and a volcano, and be prepared to compare them in terms of wealth
- Use a named example of a tropical storm to illustrate effects and responses
- Use a recent extreme weather event in the UK to illustrate causes, impacts, and management
- Be able to explain the difference between mitigation and adaptation strategies for climate change
- Use specific geographical terminology throughout your answers
- Ensure you can draw and label a food web or nutrient cycle diagram.
- Use specific case study names and locations to support your arguments.
- Focus on the 'interdependence' aspect—how changing one component affects the whole system.
Common Misconceptions & Mistakes to Avoid
- Confusing primary and secondary effects
- Confusing immediate and long-term responses
- Failing to link tectonic processes to specific plate margin types
- Generalising about climate change causes without distinguishing between natural and human factors
- Failing to use named examples as required by the specification
- Confusing the roles of producers, consumers, and decomposers in nutrient cycling.
