Theory question 106
Nigeria: Physical Setting(a) Draw an outline map of Nigeria. On the map, show and name: (i) longitude 15°E; (ii) Udi Hill; (iii) Lokoja. (b) Outline three importance of highlands in Nigeria. (c) Identify four development problems arising from the presence of highlands in Nigeria.
Show the model answer
(a) Outline of Nigeria with title and north arrow; longitude 15°E as a line near the eastern border (through the Lake Chad area); Udi Hill (Udi Plateau) in the south-east near Enugu; Lokoja at the Niger-Benue confluence.
(b) Source of minerals (tin and columbite on Jos Plateau, coal at Udi); source of rivers; cause relief rainfall; cool climate for tourism and resorts; grazing land; sites for HEP; defence; special crops (e.g. Irish potatoes on Jos Plateau).
(c) Barrier to road and rail construction; high cost of building infrastructure; soil erosion on steep slopes; difficult farming and mechanisation; scattered settlements; rain shadow on leeward sides; landslides; inaccessibility.
Mark longitude 15°E clearly.
