The Geographical Enquiry Process

Turning a geographical topic into a question

A geographical enquiry is an investigation that uses evidence to answer a question about places, processes or issues. It might investigate changes along a river, the effects of coastal management or the success of urban regeneration. The question gives the investigation a purpose: it determines which evidence is relevant and what to do with it.

A topic such as rivers is too broad to guide an investigation. A question such as “How do channel width and depth change downstream along the surveyed section of a local river?” is more useful. It identifies what will be investigated, where the comparison will take place and which characteristics need measuring.

Enquiries should connect to geographical concepts or processes. Here, the concept is the river’s cross profile: the shape of its channel from one bank to the other. Width and depth provide evidence about that shape. An enquiry does not have to investigate an entire river from source to mouth; a safe, accessible section with opportunities to investigate change can be suitable.

Questions, hypotheses and sub-questions

An enquiry question asks what you want to find out. A hypothesis states a prediction that evidence can test. For the river investigation, a possible hypothesis is: “Channel width and depth differ between the upstream and downstream survey sites.” This is a prediction to investigate, not an established result.

A useful question must be answerable with the time, locations and evidence available. “What is this river like?” gives little guidance. Asking about width and depth makes it much clearer what observations are needed.

A main question can be divided into sub-questions. For this investigation, these could be:

• What are the channel width and depth at each survey site?
• What similarities or differences occur between the sites?
• Is there a consistent downstream pattern, or do some sites differ from it?

These questions form a logical progression. You first establish the measurements, then compare them, and then identify a pattern. Each contributes to answering the main question.

Building a connected enquiry sequence

A sequence of enquiry is more than a list of tasks. Each stage should produce something needed by the next.

1. Identify the question and its geographical basis. Decide what you want to investigate and which concept or process makes it geographical.
2. Plan the evidence and methods. Decide what information would answer the question, where to obtain it and how to collect it safely. In the river example, this means selecting suitable survey sites and planning width and depth measurements. Site choice matters: unsuitable water levels or unsafe access could prevent the investigation from working.
3. Collect and record relevant evidence. Measure width and depth at the selected sites, recording which results belong to each location. Using consistent methods makes comparisons more meaningful.
4. Process and present the evidence. Organise the results so that comparisons are possible. Cross profiles drawn to scale can show channel shape, while graphs can help compare measurements between sites.
5. Interpret the findings. Look for patterns, differences and results that do not fit the general pattern. Use these observations to address the sub-questions and then the main question.
6. Answer the question and review the enquiry. Decide what the evidence supports, then consider how the choice of sites and methods limits the answer and what could be improved.

The sequence can also involve returning to an earlier stage. If initial planning shows that depth cannot be measured safely at the intended sites, the locations or question may need adjusting before data collection.

Choosing evidence because it answers the question

Relevant evidence is evidence that helps answer the enquiry question. River width and depth measurements directly address the question. A questionnaire about visitors’ favourite riverside cafés would not, even if it were easy to carry out there.

The same principle applies to human geography. An enquiry into urban regeneration might use pedestrian counts to investigate how much an area is being used. Background research into the reasons for the regeneration project can help establish what it was intended to achieve. However, pedestrian counts alone would not answer every possible question about its success: the evidence chosen must match the particular question being asked.

A manageable enquiry with a clear question and a few well-chosen methods is more useful than a complicated investigation collecting information without a clear purpose.

Identify the question

• Start with a geographical concept, process or issue.
• Specify what you will investigate and where.
• Check that relevant evidence can be obtained safely within the available time.
• Question: asks what you want to find out.
• Hypothesis: predicts something that evidence can test.
• Use sub-questions to divide the main question into manageable parts.

Recall the sequence

Question → plan → collect and record → process and present → interpret → answer and review.

Each stage must support the next. Adjust the plan if the proposed evidence or locations are unsuitable.

Keep the enquiry connected

Choose evidence because it answers the question. For changes in river channel shape, width and depth are relevant; unrelated visitor preferences are not. The final answer must address the original question, within the limits of the evidence collected.
