Written sources require interpretation at multiple scales, ranging from local impacts to global trends. Students must extract relevant data to understand the complexities of a geographical issue.
A critical skill is justification, where a student selects a possible solution or option regarding a geographical problem and uses specific evidence from the text to support their reasoning.
Secondary sources often provide the 'why' and 'how' that photographs cannot, such as historical context, community opinions, or statistical data regarding population and economy.
| Feature | Observation (Pictorial) | Inference (Interpretation) |
|---|---|---|
| Source | Direct visual evidence | Logical deduction based on evidence |
| Scope | Limited to what is visible | Extends to causes and effects |
| Example | 'There are many high-rise buildings.' | 'This is a high-density financial district.' |
| Exam Goal | Accurate description | Justified explanation |
It is vital to remain objective. For example, a photograph can show a 'dry riverbed' (observation), but stating 'it hasn't rained in months' is an inference that may require written data to confirm.
The 'Visible Only' Rule: In exam questions asking to describe a photograph, never include information that is not explicitly shown. Avoid mentioning sounds, smells, or internal feelings of people in the image.
Categorization Strategy: When asked for a general description, organize your answer into 'Physical' and 'Human' subheadings to ensure a comprehensive response and to help the examiner track your points.
Evidence-Based Justification: When using written material to support a decision, use direct quotes or specific data points. A vague reference is less effective than saying, 'According to the report, 60% of the residents support the new dam...'
Check the Scale: Determine if the material refers to a local, regional, or national context, as this changes the significance of the geographical features described.
