Edexcel GCSE Geography A (1GA0) — Geographical Investigations: Fieldwork and UK Challenges
Every time geographers visit the coast to measure a beach, they follow a systematic process to ensure their data actually answers a specific question. The enquiry framework is a six-stage sequence used to conduct geographical investigations, starting from identifying a context to reaching evaluated conclusions. For Edexcel Specification A, the prescribed fieldwork focus is the investigation of coastal processes through landscape evidence.
The specific task chosen dictates the geographical scope and sampling strategy of your fieldwork. A "processes" task (Task 1) focuses on how wave energy and materials interact to shape the landscape. Because the goal is to observe a natural sequence, such as longshore drift, the scope usually involves taking measurements along a transect to show continuous change over distance.
Conversely, a "management" task (Task 2) focuses on how human intervention alters the natural system. This scope must be comparative. It requires assessing at least one managed site (e.g., with groynes) against an unmanaged control site to isolate the impact of the human defence.
A strong enquiry question or hypothesis must be specific and testable. Geographers use SMART criteria (Specific, Measurable, Achievable, Relevant, and Time-bound) to ensure an investigation can be realistically completed in one field day.
When suggesting an enquiry question, combine a geographical variable with a precise location:
Primary data is information collected first-hand during the fieldwork. Edexcel requires students to use at least one quantitative method and one qualitative method.
Quantitative methods often measure beach morphology, such as using clinometers and ranging poles to calculate a beach profile. When collecting this data, students must consider reliability by taking repeated samples, and accuracy by using precise tools like digital calipers. Qualitative methods, such as annotated field sketches, capture landforms that numbers cannot fully describe.
Secondary data is information collected by someone else, and it is essential for providing context to your primary results. The British Geological Survey (BGS) Map Viewer is a mandatory secondary source that identifies solid bedrock and younger, overlying superficial deposits.
Secondary geology maps provide a causal explanation for the erosion rates measured in the field. For example, if primary data shows rapid coastal recession at Holderness, BGS maps explain why. Finding soft glacial till on the map reveals the cliff's lithology is unconsolidated; because unconsolidated rocks lack structural strength, they are easily eroded by hydraulic action, explaining the rapid retreat (up to 2m/year).
Historical Ordnance Survey (OS) maps and Shoreline Management Plans (SMPs) provide a long-term baseline to compare against a single day of fieldwork. By comparing the position of a historical shoreline to a modern satellite image, geographers can calculate the long-term rate of erosion:
Comparing your primary fieldwork measurements to the National Coastal Erosion Risk Map (NCERM) helps identify anomalies. If your measured erosion is much higher than the historical average, it may be due to a recent isolated storm event rather than a permanent change in wave energy.
Students often confuse reliability with accuracy. Reliability is about consistency (e.g., repeating a pebble sample three times), whereas accuracy is about the precision of your equipment (e.g., using digital calipers to measure to the nearest 0.1mm).
In exam questions asking you to 'Justify' your fieldwork location for a physical processes task, examiners expect you to explain that a single landform (like a spit) allows you to use a transect to observe a natural sequence of change.
If asked to 'Suggest' an enquiry question, always name a specific location and include a measurable variable (e.g., 'beach gradient' or 'sediment size') to ensure it meets the 'Specific' and 'Measurable' requirements of the SMART criteria.
When asked to 'Explain' the use of a BGS geology map in an exam, explicitly use the term 'lithology' and link it to your primary erosion measurements to secure the causal explanation marks.
Enquiry framework
The systematic six-stage process used to plan, conduct, and evaluate geographical investigations.
Coastal processes
The physical mechanisms, such as erosion, transportation (e.g., longshore drift), and deposition, that shape the coastal landscape.
Transect
A straight line across a landscape along which data is collected at regular intervals to show continuous spatial change.
Enquiry question
A specific, measurable question that sets the focus and guides the entire geographical investigation.
Hypothesis
A testable prediction about the relationship between two geographical variables.
SMART criteria
A framework ensuring that an enquiry question is Specific, Measurable, Achievable, Relevant, and Time-bound.
Primary data
Original data collected first-hand by the researcher in the field.
Beach morphology
The physical shape, gradient, and width of a beach.
Reliability
The consistency of measurements, which can be improved by taking multiple repeated samples to avoid anomalies.
Accuracy
How close a recorded measurement is to the true value, often improved by using more precise equipment.
Secondary data
Information collected by someone else that is used to provide a baseline or context for primary fieldwork.
Bedrock
The solid, underlying rock beneath surface soils and superficial materials.
Superficial deposits
Younger, loose materials such as sand, clay, or glacial till that lie over older bedrock.
Coastal recession
The landward retreat of the shoreline over time due to coastal erosion.
Lithology
The physical characteristics of rocks (such as hardness and permeability) that determine their resistance to erosion.
Unconsolidated
Loose material that is not cemented into solid rock, making it highly vulnerable to erosion.
Shoreline Management Plans (SMPs)
A document produced by local authorities outlining the long-term strategy for managing a specific stretch of coastline.
