Study the map extract on a scale of 1:100,000 and answer the following questions:
(a) Draw an outline of the map using a scale of 1:300,000 On your outline, mark:
(i) an area liable to flooding;
(ii) the full length of River Rafin Bela and its direction of flow;
(iii) the settlement of TILL! and ZOGIRMA; and
(iv) shade completely the area above 800ft around ZANUA HILL
(b) Identify any four distinct drainage features on the map
(c) If you are travelling along the minor road from Rafin Tsaka to Nageda, name any six features, physical and human, you will come across on your way.
Explanation
(a) Draw an outline of the map using a scale of 1:300,000. To reduce the map thrice its size,
Length = 37.5cm ÷ 3 = 12.5 cm.
Breadth = 36.6cm ÷ 3 = 12.2cm.
If the original scale of the map is 1:100,000; therefore, the reduced scale will then be
1:100,000 x 3
= 1:300,000. (This is the scale of the new outline).
(b) Drainage features found on the map:
(i) meanders
(ii) watersheds
(iii) floodable plains
(iv) Braiding
(v) River valley
(vi) Dendritic drainage pattern
(c) Human and physical features found along the road.
Human features:Include, settlements, bench marks, scattered cultivation, wells and footpaths.
Physical features: Include, scrub, plain, hill and river valley.
