Physical Geography of Sub-Sahara Africa
  • Sub-Sahara refers to Africa SOUTH of the Sahara
    desert.
  • Includes almost 50 countries. One-third of all
    the countries on the earth.
  • Extremely diverse landscape.
  • 2nd largest continent has 9 million square miles
    of huge plateaus, mountains, and valleys south of
    the Sahara.

2
Continent of Plateaus
  • One big Plateau
  • Coastal plains go 20 miles inland.
  • Plateau after plateau in between there are
    escarpments.
  • Escarpments- steep cliffs or slopes.
  • South East hold steepest escarpments.
  • B/C of plateau Africa has the highest overall
    elevation

3
Mountains
  • Atlas in Northwest.
  • Most mts. east side.
  • Drakensberg, Ruwenzori.
  • Volcanoes Mount Kenya, Mount Kilimanjaro,
    Africas highest peak (19,340 feet)

4
Great Rift Valley
  • Stretches from Jordan river to Zambezi River in
    Mozambique.
  • Occurred when pangaea ripped apart creating
    mountains.

5
Water Systems
  • Largest lakes cut into Great Rift Valley.
  • Longest rivers all rise in plateaus.
  • Due to high escarpments, rapids and waterfalls
    are common on the edge of the continent.

6
Lakes
  • Lake Victoria in GRV, 2nd largest freshwater lake
    in the world, source of White Nile.
  • Lake Tanganyika (420 miles) 1st largest lake in
    world.
  • Lake Malawi in GRV
  • Outside GRV Lake Volta, Lake Chad (no natural
    outlet-loses water through evaporation.

7
Rivers
  • 4 great rivers slice through Africa
  • Nile
  • Congo (largest river system sub-Sahara)
  • Niger
  • Zambezi (plunges down a huge chasm known as
    Victoria Falls, which is twice the size of
    Niagara falls)

8
Natural Resources
  • Diamonds form the D.R.O.T. Congo.
  • Gold from South Africa GRV.
  • Nigeria 3 of worlds known oil.
  • Uranium, manganese, cobalt, zinc, copper.

9
Climate Vegetation
  • Three tropical latitudes cross sub-Sahara Africa.
  • T of Cancer crosses south of Sahara Desert
  • T of Capricorn extends through southern tip.
  • Equator runs through center. (All Africa within
    35 degrees of equator)
  • B/C sub-Sahara is all in the tropics makes for
    diverse climate and vegetation.

10
Deserts
  • Deserts cover a larger percentage of Africa than
    any other continent.
  • Sahara covers north.
  • Namib desert, coast of Namibia.
  • Kalahari desert most of Botswana.

11
The Sahel
Looking south
  • Sahel means border.
  • Lies between the desert and fertile grassland to
    the south.
  • Long, dry seasons wet seasons.
  • Drought has brought famine, misery, hardship.

    taking over.

Looking north
12
Tropical Savanna Tropical Rain Forests
  • T.S. more rain than Sahel, supports livestock and
    game.
  • T.S. Holds the Serengeti plains and Nairobi
    national park.
  • T.R.F. covers only 8 of Africa, on the equator.
  • T.R.F. faces destruction from logging companies.
