Theory question 112
Geography of Africa(a) Draw an outline map of Africa and on it locate: (i) Latitude 0° and longitude 20°E (ii) one named ocean current along the Western coast and one along the Eastern coast (iii) two named deserts (one in the North and the other in the South) (b) Give three reasons for the presence of deserts in the north of Africa.
Show the model answer
(a) Equator through Gabon, Congo, Uganda, Kenya; 20°E through Libya, Chad, Congo, Namibia/South Africa border area; Benguela or Canary current on the west, Mozambique or Agulhas current on the east; Sahara in the north, Kalahari or Namib in the south.
(b) Dry north-east trade winds blowing from the land; sub-tropical high pressure with descending, warming air; great size and distance from the sea (continentality); cold Canary current drying winds on the west coast; high evaporation; rain shadow of the Atlas Mountains.
Draw the equator and 20°E as straight lines across the continent.
