questions:
• When you hear the word “AFRICA”, what images come to
mind?
• What do you think it’s like in Africa?
• Do you think it’s always been this way?
• How big is Africa? How many countries are in Africa?
Congo River
•It is the second longest
river in Africa at 2920 miles
(the Nile is the longest).
•It is the ninth longest river
in the world.
•The Congo River is the
deepest river in the world. It
reaches depths of over 750
feet
•The Congo River is so
powerful that if has the
potential to supply all of
sub-Saharan Africa's
electricity needs.
What lives in the Congo River?
Niger River
• The Niger is the thirdlongest river in Africa, at
2600 miles
• The Niger has an unusual
route
• It starts approximately 150 miles
from the Atlantic
• Instead of flowing to the nearby
Atlantic Ocean it instead heads
inland, away from the sea into
the Sahara Desert.
• It turns sharply near the city of
Timbuktu and heads to the Gulf
of Guinea.
• Unlike the Nile, the Niger is
very clear. This is because its
source contains very little
silt
Nile River
• It is the longest river in the world.
It is approximately 4,160 miles
• The Nile river flows from the high
mountains in the middle regions
of Africa north to the Nile delta.
• The Nile flows through 9
countries: Egypt, Zaire, Tanzanian,
Rwanda, Uganda, Burundi,
Ethiopia, Sudan, and Kenya.
• Ancient Egyptian civilization grew
from the Nile River
• The Aswan High Dam was built to
control the annual flooding of the
Nile; it also provides tremendous
hydroelectric power
Zambezi River
• The river is an amazing 2,200
miles
• There are several waterfalls on
the Zambezi including the
amazing Victoria Falls,
• The river has many rapids
and therefore has never
been a used for longdistance travel.
• Bull sharks (also called Zambezi
Sharks) which normally live in
costal waters have been known
to swim very far up the Zambezi
River.
• Compared to the other major
rivers in Africa the Zambezi has
been little explored.
Lake Chad
• Historically large, shallow,
endorheic (inland
basin) lake in Africa, the size of
which has varied over the
centuries.
• The Lake is economically
important, providing water to
more than 30 million people
living in the four countries
surrounding it
• The shrinking of the lake has
also caused conflicts to emerge
as to which countries that
border Lake Chad have the
rights to the remaining water.
Lake Tanganyika
• Lake Tanganyika is
an African Great Lake.
• The lake is divided among four
countries
• Tanzania,
• the Democratic Republic of the
Congo
• Burundi
• Zambia
• The enormous depth and
tropical location of the lake can
prevent ‘turnover’ of water
masses, meaning much of the
lower depths of the lake is socalled ‘fossil water’ and is
anoxic (lacking oxygen).
Lake Victoria
• It is Africa's largest lake and
has a surface area of 26,600
square miles
• It is the largest tropical lake in
the world.
• It is the world's second largest
freshwater lake measured by
surface area. The only larger
freshwater lake is Lake
Superior in North America.
• Approximately 80 percent of
the lakes water comes from
rain. The other 20 percent
comes from small streams
flowing into the lake.
Atlas Mountains
• The mountain range stretches
approximately 1,600 miles
(2,500 kilometers) across
Morocco, Algeria, and Tunisia
• The windward side of the mts
face the Mediterranean and
Atlantic ; the leeward faces the
Sahara Desert.
• Mineral deposits found in this
mountain range include gold,
silver, zinc, lead, and iron.
• Many indigenous species are
now extinct including: North
African Elephant and the
Barbary Lion
Ethiopian Highlands
