Sub-Saharan Africa
3
Geography The worlds second largest continent
most nations of any continent Newest country South Sudan Location and Effects Above and below equator Between two oceans; Atlantic & Indian – linked and isolated Part of major trade routes since ancient times
4
Newest country South Sudan
Capital: Juba
5
Regions North Africa – above the Sahara Desert Sub-Saharan Africa
Linked to the Middle East culturally Sub-Saharan Africa West Africa – extends into Atlantic Part of major slave trade routes to new world Central Africa – home to Africa’s tropical rain forests Southern Africa – crucial to trade b/w oceans East Africa – Great Rift Valley, fertile land
7
Landforms The land made exploration difficult for Europeans = natural barriers Africa is a continent of Plateaus Escarpments: steep cliffs & basins, swamps, lakes Mountains: edges – Atlas Mts, Drakensberg Range Great Rift Valley – a giant fault – Red Sea to Zambizi River Series of mountain, valleys, lakes Rich in natural resources, fertile soil Hard to mine and transport because of the rough terrain Olduvai Gorge: bone that belonged to the ancestors of modern people Deserts: Sahara (largest), Kalahari Coastal Plains
10
First discovered by anthropologist Mary Leakey on July 17, 1959
11
Nile, Congo (Zaire), Niger, Zambezi
Rivers Provide food, transportation, irrigation and hydroelectric power Cataracts: waterfalls; river rapids Major Rivers Nile, Congo (Zaire), Niger, Zambezi
12
Nile River – East Africa
Longest flowing river in the world 4,160 miles – flows north Home to early civilizations Predictable floods supported huge population Aswan High Dam Pros – Hydroelectric Power, Irrigation Cons – Farmers upstream now need to purchase fertilizers
13
Nile River Route and its tributaries
14
Zaire (Congo) River Niger River West Africa Central Africa
Provides hydroelectric power Cannot be navigated with boats Poor for trade Niger River West Africa Provides water for irrigation Floods predictably
15
Zaire (Congo) River
16
Niger River
17
Zambezi River Southern Africa
Creates Victoria Falls, 1 mile wide and 420 ft. high, between Zambia and Zimbabwe The Kariba Dam provides hydroelectric power
18
Victoria Falls (Zambezi River)
20
"The smoke that thunders" is a local name for Africa's most famous waterfall thundering over a 100m-high cliff. Mosi-O-Tunya
21
Africa’s Natural Resources
23
Rich source of resources
Mineral Resources (see map) Resources unevenly distributed Gold and Diamonds Profits from African nations often end up in foreign countries Europeans mined much of their gold from west Africa beginning in the Age of Discovery Power-Wealth-Trade

25
Africa’s Resources Today
Copper – Zaire and Zambia Platinum and Cobalt – S. Africa, Zaire, and Botswana Oil – Nigeria, Botswana, Libya, Algeria, and Gabon Profits from African nations often end up in foreign countries
26
Adapting to the Land Societies developed near sources of water
hunting and gathering farming herding fishing urban Major urban areas developed on the Mediterranean Coast, western savannas, and East Coast
27
Language More than 1,000 languages
Groups only a few miles apart often speak different languages Small tribes migrated constantly and used their own language Scholars group African Languages into large families Trade and diffusion created new languages Swahili: Bantu and Arabic

Section 1 Quiz Answers E Hydroelectric Power D cataract A escarpment
C Nile B Aswan Dam 6. B the Pacific Ocean 7. A mountains 8. C 4,000 mile fault line that splits the continent 9. B halted annual flooding of the Nile 10. B seize a share of Africa’s gold and diamonds
29
Climate and Diversity
30
Climate Facts Latitude and Elevation = climate
Most tropics = area between Tropic of Cancer and Capricorn of all the continents Temperature is warm to hot Colder temperatures seen in higher elevations Therefore, rainfall distinguishes the climate in Africa not temperature Precipitation – Less than an inch to more than 80 inches
31
Climate Zones Tropical Wet Tropical Wet and Dry Desert Mediterranean
33
Climate Map of Africa
35
Tropical Wet – 8% of Africa
Narrow strip along equator Home of the rainforests Average Temp – 80 F Average Rain – inches per year Hard to settle Leaching: rain washes away nutrients and destroys soil, unsuitable for farming Moisture feeds disease and destroys daily items Concrete and steel are expensive fixes Disease from insects; sleeping sickness, malaria (Nothing But Nets)
36
Tropical Wet and Dry – 50% of Africa
Either side of tropical wet climate to the tropics Rainfall varies by season Summer – Hot temps & Rainy Season Winter – Warm temps & Dry Season Major Feature Savanna – most people - grasslands that cover half the continent. More rain near the equator support plant and wild life Sahel: semi-arid; separates Sahara from savanna Unpredictable rainfall makes daily life difficult Drought Desertification – land turning into deserts; causes over grazing and drought
37
Deserts and Desertification
38
Deserts – 40% of Africa Sahara – Means ‘desert’ in Arabic – Northern Africa Larger than the continental United States Rain rarely falls, less than 10 inches a year Temperatures reach as high as 130 F Traders traveled across the Sahara Diffusion of European, Asian, and African cultures Kalahari – Southern Africa More rain than the Sahara allows food to grow Namib – Southern Africa
39
The Sahara Desert
40
Kalahari Desert
41
Deserts – 40% of Africa Namib Desert – one of the driest places on Earth One of the oldest deserts in the world: 80 million years Averages less than .4 inches of rain a year Dune 7: the highest sand dune in the world, 383 meters ~ 1200 feet
42
Namib Desert
43
Mediterranean - ~2% The Southern Tip and the Northern Coast
Climate similar to LA Hot, Dry Summer Cool, Wet Winter Fertile soil good for farming Major travel destination
44
Mediterranean Zones are in Purple
45
Answers to Section 2 Quiz
C Kalahari E Sahel A Sahara D Tropic of Capricorn B Tropic of Cancer 6. C-Desert 7. A-Tropical wet zone 8. D- in the savanna 9. D- all languages belong to one language family 10. B- they carry diseases that are fatal to humans
46
Early Civilizations of the Nile Valley
47
Egypt Kush I. Religion -played a major role in daily life
-polytheistic -God’s controlled forces of nature -life after death -priests and pyramids -pharaoh ruler of Ancient Egypt considered a god II. Economic Activities -farming -trade III. Achievements -hieroglyphics -365 day calendar -math -medicine -art Kush

Kush I. Achievements - 750BC
- King Kastha conquers Nile Valley for short time -Meroe: capital city -adapted hieroglyphics II. Historical Importance -Egyptian Influence -polytheistic -grew rich and powerful from iron industry (learned from Assyrians) -traded with Egypt and Mediterranean world -weakened by invasion and internal rivalries
52
Meroe Pyramids
53
Axum I. Achievements - 350 AD -King Ezana conquered Kush
-sacred writing (geez) -controlled port cities (ivory trade) II. Historical Importance -present day Ethiopia -center of trade -Ethiopic Church (one of the oldest forms of Christianity) -lost power to Muslim empires
54
What were the results of the interaction between civilization?
Closure What were the results of the interaction between civilization? exchange of knowledge and ideas diffusion
55
Africa: Geography and Early History
Open-Ended Questions
56
What is a key factor in differentiating between Africa’s climates because temperatures do not vary greatly from place to place? Amount of Rainfall
57
List 5 types of societies of Africa
Hunting and gathering Farming Fishing Herding Urban
58
Factors that influences where people live in Africa.
Environment Climate Geography Availability of water and resources
59
Tropical Wet Tropical Wet and Dry Desert Mediterranean
Identify Africa’s climate regions and describe ways in which that climate has affected the ways of life of the African people. Tropical Wet Hard to settle because of leaching, insects, disease, mold and rot Tropical Wet and Dry Unpredictable/unreliable rainfall difficult on farmers/herders, desertification caused by people but still home to most Africans Desert Few areas have grasses to support herding, not enough rain for farming Mediterranean Supports farming and herding=large population
60
Describe ancient Egypt in terms in terms of religion, economy activities, and achievements.
polytheistic, connected to nature, life after death, Pharaoh Economic Activities trade, farming Achievements hieroglyphics, 365 day calendar, math, medicine, art, architecture
61
Bonus Info: Civilization of the Nile Valley
Kush Rich from iron industry Meroe: capital city, center of trade Axum King Ezana convert to Christianity Ethiopic Church Center for trade
