Physical systems

OCR

A-Level

Landscape Systems introduces the integrated study of Earth surface processes, landforms, and resultant landscapes within a systems approach. It covers three optional landscapes (Coastal, Glaciated, or Dryland), focusing on the inter-relationships between land, oceans, and atmosphere, and the management of these dynamic systems.

Physical systems

Topic Overview

Physical systems in OCR A-Level Geography explores the dynamic natural processes that shape our planet, focusing on the interactions between the atmosphere, lithosphere, hydrosphere, and biosphere. This topic is divided into two key areas: landscape systems (coastal and glaciated landscapes) and the water and carbon cycles. You will investigate how energy flows and material transfers create distinctive landforms, how these systems respond to change, and the critical role they play in supporting life and regulating Earth's climate. Understanding physical systems is essential for grasping the interconnectedness of natural environments and the impacts of human activity on global processes.

Why does this matter? Physical systems are the foundation of many contemporary geographical issues, from coastal erosion threatening communities to the role of forests and oceans in carbon storage. By studying these systems, you develop skills in systems thinking, data analysis, and field investigation—core competencies for geographers. This knowledge also underpins debates about climate change mitigation, sustainable resource management, and hazard resilience. In the wider A-Level, physical systems link to human geography topics like climate change policy and resource security, showing how natural and human worlds are inseparable.

In your OCR exam, physical systems appear in both Paper 1 (Physical Systems) and the synoptic paper. You'll need to apply concepts to unfamiliar contexts, evaluate management strategies, and use case studies effectively. Mastering this topic means being able to explain processes like longshore drift or the carbon cycle with precision, and critically assess the effectiveness of interventions like coastal defences or afforestation. The content is rigorous but rewarding—it gives you a lens to understand the planet's most fundamental operations.

Examiner Tips

Expert advice for maximising your marks

💡Always structure answers using the systems approach where possible.
💡Ensure case studies are from the 21st century.
💡Practice applying quantitative skills like sediment budget and mass balance calculations.
💡Use clear, technical geographical terminology.
💡Ensure you can link physical processes to specific landforms clearly.
💡Use the systems framework (inputs, outputs, stores, flows) consistently in your answers.
💡Ensure case studies are specific and contemporary (21st century).
💡Practice drawing and interpreting climate graphs and flow diagrams.
💡Be prepared to discuss the interdependence between the two cycles, not just them in isolation.
💡Use precise geographical terminology (e.g., ablation, sequestration, catchment hydrology).
💡Focus on the 'why' and 'how' of human impacts, not just describing the impacts.

Common Mistakes

Pitfalls to avoid in your exam answers

Failing to explicitly use the systems framework (inputs, processes, outputs) in explanations.
Neglecting the required case study balance (UK vs. non-UK).
Describing landforms in isolation rather than as part of an inter-related system.
Ignoring the temporal scale of change (e.g., confusing short-term events like cliff collapse with long-term evolution).
Lack of focus on the specific management strategies requested in the specification.
Failing to explicitly link the water and carbon cycles together.
Confusing the specific processes of the water cycle with those of the carbon cycle.
Treating the cycles as static rather than dynamic systems with feedback loops.
Lack of specific detail in case studies (Tropical Rainforest and Arctic tundra).
Inability to apply the systems framework (inputs, outputs, stores, flows) to the cycles.
Confusing short-term (diurnal/seasonal) changes with long-term (geological) changes.
