Theory question 106
Nigeria: Physical Setting(a) On an outline map of Nigeria show and name: (i) one area with an annual rainfall below 100cm (ii) one area with an annual rainfall below 300cm (iii) two important towns in each area (b) Describe four other climatic features of the area shown in (a)(ii) above (c) Name the vegetation type associated with the climate described in (b) above and outline its characteristics
Show the model answer
(a) Area below 100 cm: far north/north-east (Sokoto, Kano, Maiduguri, Nguru). Area of very high rainfall (over 300 cm): south-east coast/Niger Delta (Port Harcourt, Warri, Calabar, Bonny).
(b) High temperatures all year (about 26-27°C); small annual range (about 2-3°C); double maxima of rainfall; no month without rain / short dry season; high humidity; heavy convectional rainfall.
(c) Rain forest/mangrove swamp forest: dense evergreen trees; tall trees in layers with continuous canopy; many species mixed together; lianas and epiphytes; mangroves with stilt roots in the coastal swamps.
The question prints 'below 300cm' for (ii); the map answer should show the very wet south-east coast.
