OCR A-Level Geography Landscape Systems: a complete overview of coasts, glaciation and drylands

What Landscape Systems actually demands

Landscape Systems is the opening topic of Component 1, Physical systems, and it forms Section A of Paper 01. OCR tests two linked skills: precise understanding of physical processes and the confident application of systems concepts and located case studies to data and essay questions. The unifying idea is that any landscape, coastal, glaciated or dryland, is an open system with inputs, stores, flows and outputs that tends towards dynamic equilibrium.

This guide walks through the shared framework, then each landscape option, then the human management strand, and finally the exam patterns OCR repeats. Each topic has a matching dot-point page with worked exam questions; this overview ties them together.

The systems framework that underpins every option

Whichever landscape you study, the structure is the same. Inputs are energy (wind, waves, ice, gravity, solar) and matter (sediment); stores are the landforms; flows or transfers are the processes that move sediment; and outputs are sediment and energy leaving the system. The balance of inputs and outputs is the sediment budget, which predicts whether a landscape erodes or accretes. Negative feedback maintains dynamic equilibrium; positive feedback amplifies change; and crossing a threshold establishes a new equilibrium. Master this once and it carries across coasts, glaciers and deserts alike. See the Landscape systems and change page for the full treatment.

Coastal landscapes

Coastal landscapes treats the coast as a system within a sediment cell. Energy comes from constructive and destructive waves, tides and currents; marine (hydraulic action, abrasion, attrition, solution, longshore drift) and sub-aerial (weathering, mass movement) processes create erosional landforms (headlands and bays, caves to stacks, wave-cut platforms) and depositional landforms (beaches, spits, bars, tombolos, dunes). Sea-level change adds emergent (raised beaches) and submergent (rias, fjords) landforms, and human activity and climate change modify the whole system.

Glaciated landscapes

Glaciated landscapes is governed by mass balance, the difference between accumulation and ablation. Glacial processes (plucking, abrasion, unsorted till deposition) carve corries, aretes, pyramidal peaks and troughs and deposit moraines and drumlins; fluvioglacial processes deposit sorted outwash, eskers and kames; and periglacial processes (freeze-thaw, solifluction, permafrost) create ice wedges and patterned ground. The topic ends with the distribution, value, threats and sustainable management of cold environments.

Dryland landscapes

Dryland landscapes covers arid and semi-arid systems controlled by climate and tectonics. Aeolian processes (deflation, abrasion, dune building) and episodic but powerful fluvial processes (flash floods, wadis, alluvial fans), with intense mechanical weathering, create the landforms. The topic adds desertification and its physical and human causes, and the sustainable management of fragile drylands.

The human management strand

Across all three options, OCR asks how human activity and management modify the system. Managing landscape systems compares hard engineering, soft engineering and managed realignment, sets out the Shoreline Management Plan policies, and weighs the conflicts between players and the sustainability of management as climate change raises risk.

How Landscape Systems is examined

A typical OCR profile for Section A of Paper 01:

• Data-response and resource questions. Reading sediment-cell diagrams, climate graphs, maps and photographs, often Using Fig. X, and describing patterns (AO3).
• Process explanation. Linking named processes to named landforms (longshore drift to a spit, plucking and abrasion to a corrie, deflation to a desert pavement).
• Calculation. Sediment budgets, recession rates and mass-balance figures, with interrogation of the assumptions (AO3).
• Extended essay. A 16-mark question rewarding evaluation and a supported conclusion, for example assessing the relative importance of marine and sub-aerial processes.
