  3. 3. Physical Geography <ul><li>PHYSICAL FEATURES </li></ul><ul><li>Sahara Desert </li></ul><ul><li>smooth coastline </li></ul><ul><li>lack of navigable rivers </li></ul><ul><li>Great Rift Valley </li></ul><ul><li>high plateau </li></ul><ul><li>RESULT </li></ul><ul><li>Groups are kept separate - - </li></ul><ul><li>800 different languages are spoken in modern Africa </li></ul>

  5. 5. Topography <ul><li>Deserts </li></ul><ul><ul><li>40% of the land surface of Africa </li></ul></ul><ul><ul><li>slows cultural diffusion - does not totally prevent it </li></ul></ul><ul><li>Sahara -- North Africa </li></ul><ul><ul><li>1/3 of the continent (= to the USA!!) </li></ul></ul><ul><ul><li>majority is rock and gravel </li></ul></ul><ul><li>Kalahari--Southwest Africa </li></ul>
  6. 6. True desert spreads into semi-arid regions
  7. 7. Mountains <ul><li>East Africa- </li></ul><ul><ul><li>caused by volcanic activity </li></ul></ul><ul><ul><li>section of the land sank - causing the Great Rift Valley </li></ul></ul><ul><ul><li>Atlas (NW) </li></ul></ul><ul><ul><li>Drakensberg (SE) </li></ul></ul><ul><ul><li>Ethiopian Highlands </li></ul></ul><ul><ul><li>Famous peaks - Mt.

  10. 10. CONGO ,NIGERIA AND ZAMBEZI RIVERS <ul><li>Waterfalls and rapids prevent easy navigation </li></ul><ul><li>Congo - 3000 miles long </li></ul><ul><li>Niger - ancient civilizations flourished here </li></ul><ul><li>Zambezi - Victoria Falls, used for hydro-electric power </li></ul>
  11. 11. Coastline <ul><li>Smooth </li></ul><ul><li>Few natural harbors - hard to land ships </li></ul>
  12. 12. Climate - determined by rainfall, latitude and elevation <ul><li>Savanna - 40%, safari!! </li></ul><ul><li>Tropical Rainforest - 8%, </li></ul><ul><li>Desert - 40% </li></ul><ul><li>Mediterranean - 12%, good farm land </li></ul><ul><li>About 85% of the land is not suited to farming </li></ul>
  13. 13. Natural Resources <ul><li>Farming </li></ul><ul><ul><li>peanuts, cotton, cocoa, coffee </li></ul></ul><ul><li>Minerals </li></ul><ul><ul><li>diamonds, gold, copper, cobalt </li></ul></ul><ul><li>Water </li></ul><ul><ul><li>hydroelectric power </li></ul></ul>
