Question 1 Report
Study the map extract on a scale 1:100,000 and answer the following questions:
(a) Draw an outline of the area to a scale of 1:300,000.
(b) On your outline, insert and name:
(i) the settlements of Pindiga and Yalo;
(ii) one 1900 ft contour line;
(iii) the minor roads.
(c) Calculate the actual distance along the minor road from Futuk to the point where it leaves the area on the map.
(d) Describe the influence of relief and drainage on the distribution of settlements shown on the map.
Answer Details
(a) and (b) Reduced outline and inserted features
The scale is reduced from 1:100,000 to 1:300,000. Thus, every map measurement is divided by 3. The outline is therefore 12.2 cm by 12.2 cm.
(c) Actual distance along the minor road from Futuk to the point where it leaves the map
Measured length of the winding road on the original map = 13.5 cm.
At a scale of 1:100,000,
\[1\text{ cm} = 100{,}000\text{ cm} = 1\text{ km}.\]
\[ \text{Actual distance}=13.5\text{ cm}\times 1\text{ km per cm}=\boxed{13.5\text{ km}}. \]
(d) Influence of relief and drainage on settlement distribution
- The undulating plain in the eastern part of the area has many settlements because the land is relatively gentle and suitable for farming and building.
- Most settlements are located close to river valleys, where water is available for domestic use and farming.
- Settlements avoid low river valleys that are liable to flooding. The south-eastern part has no settlement because of flood-prone drainage conditions.
- Few or no settlements occur in the highland areas of the west, north-west and south-west, where the slopes are steep and the terrain is less suitable for settlement and cultivation.
