African Geography
• Africa is a land of many contrasts: deserts, lakes, mountains, grasslands, and rainforests.
• With diversity in its people, culture and languages, it is unique yet still
African Geography
• The Sahara is the world’s largest hot desert, covering most of Northern Africa.
• About 3000 miles wide and 1200 miles long, it stretches from the Red Sea to the outskirts of the Atlantic Ocean and meets the sahel.
African Geography
• The Sahara's topographical features include shallow basins, large oasis depressions, serirs or regs (gravel-covered plains), plateaus, mountains, sand sheets, dunes and sand seas (ergs).
• The highest part of the desert is at the summit of Mount Koussi, which is 11,204 feet (3,415 m) high.

• The Nile receives its name from the Greek “Neilos”, which means a valley or river valley. The river flowed northward and flooded the lands in Egypt, leaving behind black sediment.
African Geography
• The Niger River - 3rd longest on the continent, it rises in Guinea near the Sierra Leone border and flows into Nigeria and the Gulf of Guinea of the Atlantic Ocean.
• It is a major river in West Africa• It is 2,600 mi (4,183 sq km) long, and its
middle course is navigable for about 1,000 mi (1,600 km).
African Geography
• The Atlas Mountains lie in northwestern Africa between the Mediterranean Sea and the Sahara desert.
• Located in Northern Algeria,Tunisia and Morocco, the Atlas Mountains extend approximately 1,500 miles.
• The highest range in the chain is to be found in southern Morocco.
Kalahari Desert
• Kalahari, semi- arid plateau region is located in Botswana, Namibia, and South Africa.
• The Kalahari, a 1200 mile semi-arid sandy area is covered largely by reddish sand dunes that reach as high as 200 feet and be 50 miles long.
African Geography
• Lake Taganyika is the longest lake at 420 miles as well as the 2nd deepest lake in the world (4710 feet) after Lake Victoria.
• It is bordered on the east of central Africa by Tanzania, on the north by Burundi, on the west by the Democratic Republic of the Congo (formerly Zaire), and on the south by Zambia.
African Geography
• Lake Victoria is the headwaters for the Nile River and the largest lake in Africa.
• The 2nd largest freshwater lake in the world and is shallow.
• Tanzania and Congo in the Great Rift Valley.
• Lake Victoria is bordered by Uganda, Kenya, and Tanzania

b. Locate on a world and regional political-physical map the countries of, Democratic Republic of the Congo (Zaire), Egypt, Kenya, Nigeria, South Africa, and Sudan.
Africa

SS7G3 The student will explain the impact of location, climate, and physical characteristics on
population distribution in Africa.
a. Explain how the characteristics in the Sahara, Sahel, savanna, and tropical rain forest affect where people live, the type of work they do, and how they travel.
Africa’s Climate
Climate, Work, Travel
• Where do people live? • What do they do? • Georgia Experience Reading Pp 21-22
What is Africa’s Climate?• The climate of Africa,
more than that of any other continent, is generally uniform.
• This results from the position of the continent in the Tropical Zone, the impact of cool ocean currents, and the absence of mountain chains serving as climatic barriers.
• African climatic zones can be distinguished.
HOW DOES CLIMATE INFLUENCE OTHER ASPECTS OF THE ENVIRONMENT?
• Vegetation is the most visible expression of climate
• Animal life adapts to both climate and vegetation• Soils develop in response to climate and
vegetation• Landforms• Water resources – determined by rainfall or
shortage of rainfall
WHAT IS THE IMPACT OF CLIMATE UPON PEOPLE'S LIVES?
• Regions of extreme climatic changes have few people.
• Ex: Deserts, rainforests• Climate influences agriculture - the choice
of crops grown and animals raised• People are affected to decide how to travel• Water resources – population increases • Disease is the effect climate changes
African Population
• http://na.unep.net/globalpop/africa/Appendix_6e.html
• Populations tend to live where resources are abundant for survival
