Geography: Core Concepts and Case-Study Reasoning
What you must understand
The Stage 6 course asks you to explain how biophysical and human processes interact to produce uneven outcomes across places. Be fluent with: the four spheres and their feedbacks; ecosystem functioning (energy flows, nutrient cycling, biodiversity); population dynamics and change (birth and death rates, natural increase, migration, age-sex structure, demographic transition); urbanisation and the morphology of cities; economic activity and globalisation; and human wellbeing and spatial inequality. You also need at least two contrasting case studies you can describe at two scales, with named processes, stakeholders and impacts.
Traps that appear in questions
- Confusing a process with an outcome: urban sprawl is a process; congestion and loss of peri-urban farmland are outcomes.
- Treating a model as fact. The demographic transition and urban land-use models are generalisations with exceptions; questions asking for limitations reward naming those exceptions.
- Ignoring scale. A question on "impacts" may require local, national and global consequences, and a stakeholder view (residents, government, business).
- Describing a case study without linking it to the concept named in the question.
- Using one case study for a question demanding contrast.
Worked example
Question: "Explain how migration reshapes both origin and destination places." Rule of thumb: answer in paired chains. Destination chain: labour demand attracts migrants, raising housing demand, which lifts rents and can displace low-income residents. Origin chain: loss of working-age adults reduces local labour supply and remittances may offset or entrench dependency. Then add one evaluative sentence on who benefits. Each chain must name a process, a mechanism and an outcome, not merely a list of effects.
Rule of thumb
For every concept, rehearse one sentence of definition, one mechanism, one case-study example and one limitation. That four-part structure fits most extended responses.
