Mount Kilimanjaro East African Mountains
THIS is why we see snow at the Equator!

Settlement in Africa
  • David Livingstone and Henry Stanley - African
    Explorers.
  • Settlement Patterns also impacted by plateau
    How?
  • Coastal Areas were settled, too difficult to go
    inland

Dr. Livingstone, I presume?

11
Climate Patterns
  • Africa is the only continent to have the Equator,
    Prime Meridian, and BOTH Tropic Lines to run
    through it.

12
C L I M A T E
A F R I C A N
  • There are similar climate patterns found at the
    north and the south of the continent EXCEPT that
    theyre...

reversed and mirrored ---WHY??
13
Tropical Rainforest
Desert
Savannah
Mediterranean
14
Coastal Settlements Countries
  • Many landlocked countries
  • Interior of Africa is a PLATEAU
  • Africa is a storehouse of mineral wealth gold
    and diamonds
  • Africa can make money by exporting RAW MATERIALS
    and then purchasing what they need by importing
    MANUFACTURED GOODS.
  • Potential for HYDRO-ELECTRIC power.

15
Note the disparity of wealth!!!

16
HOWEVER...
  • Africa has a lack of sustainable agriculture
  • because of the lack of arable land seasonable
    rainfall...
  • and the problem
    of infertile soil.

17
  • There is also an extensive range of climates
    from desert to rainforests
  • Arid vs. semi-arid land

18
  • Finally, there are scarce water resources
    Oasis, wadis, water holes
  • Man-made temporary water deposits
    reservoirs, wells

19
QUESTIONS
  • Why was it difficult for explorers to get to the
    middle of Africa?
  • What are some characteristics of Africas
    climate?
  • Why is there a large population along the coast
    in Africa?
  • What kinds of resources does Africa have that
    help its economic base?
