(a) Draw an outline map of Africa. On the map, mark and name the following:
(i) the Tropical Climatic region; (ii) the Hot Desert Climatic region;
(iii) the Warm Temperate Eastern Mai Climatic region
(b) Describe any three characteristics of the Tropical Climate
(c) Outline three ways in which the vegetation of the Tropical Climate has adapted to the Climatic conditions of the reg
(a) An outline map of Africa
(b) Characteristics of the Tropical Climate
(i) Distinct wet and dry seasons
(ii) temperature high between 21°C and 32°C.
(ill) Annual e of temperature is high between (Total annual rainfall varies from 6C to 150cm
(v) Average rainfall is 75cm
(vi) Rain decreases from the equatorial borders to the borders
(vii) Rainfall is of the single rainfall reg with a peak period occurring about july.
(viii) Rain is mainly convectional
(ix) Prevailing winds —Tropical maritime and tropical continental (S.) Trade winds and N.E Trade winds)
(x) Low relative humidity —between 20 — 40% in the dry season
(xi) Hot rainy season and cool dry season
(XII) High humidity in the wet season between 60% and 80%.
(c) Ways in which the vegetation of the Tropic climate has adapted to the climatic condition of the region
(1) Vegetation is seasonal in nature green in the ra season and brown in the dry season.
(2) Plants have developed bulbous stems to store wa in the dry season.
(3) Some have long taproot which can reach underground water.
(4) Some plants have thick barks, narrow, and thorny leave to reduce transpiration.
(5) Some grasses have resistant underground root system, which survive the hot dry season and bush burning
(6) Trees shed their leaves in the dry season to reduce transpiration.
