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.
Explanation
(a) Draw an outline of the area to scale of 1:300,000.
Outline length 12.2cm ; Breadth 12.2cm
Note: The original length and breadth had been divided by 3.
(b)(i) Settlement of Pindiga and Yalo.
(ii) 1900ft contour line.
(iii) Full length of two minor roads.
Note: All these had been indicated in the drawn outline. 12.2 cm
(a)(b)

(c) Calculating the actual distance along the minor road from Futuk to the point where it leaves the area on the map. The distance in the map is 13.5 cm. The scale of the map is 1:100,000. Therefore the conversion of 13.5cm to the actual distance on the ground is
= 13.5 x100,000 km = 13.5km
100,000 1
(d) The influence of relief and drainage in the distribution of settlements shown on the map;
(i) The undulating plain to east of the area has many settlements.
(ii) Most settlements are near the river valleys.
(iii) Settlements avoid river valleys that are liable to flooding e.g. no settlement in the south-east due to flooding.
(iv) Settlements avoid the highland area in the west, north-west and south-west.
