latitude & trade winds = “striped” climate & vegetation pattern on the continent.
Climate & Vegetation
Absence of coastal mtn ranges also impacts climate.
Landforms Highest point : Mt
Kilimanjaro Lowest point : Lake Assal Victoria Falls in Zambia
Mt. Kilimanjaro: Tanzania
Glacier has been melting… 80% loss from 1912 to present day.
What element of
LEMPOSA contributes to the glacier and the
snow found on Kilimanjaro?
The Mighty Nile River:
“Longest River in the World”Farmers DEPEND on this River as a source of water for their farms, and before the Aswan High Dam was built, farmers depended on the nutrients left behind as natural fertilizer for the soil and thus their crops. Negative impact for people being relocated & for farmers.
Hydroelectric PowerHydroelectric Power: An example of how humans
have MODIFIED their environment
The Sahara Desert:Desertification• Over the last 11,000 years
the Sahara has been growing…
Causes:1. Overgrazing 2. Farming “average” land3. Destruction of plants4. Incorrect irrigation 5. Changes in the Earth’s orbit 6. Atmospheric & vegetation changes in the subtropical regions.
African Savannah: 5 million sq miles
Rolling grassland scattered with shrubs & isolated trees.
Can be found between a tropical rainforest and desert biome
African Rain Forest
# Annual rainfall of up to 17 ft.# Rapid decomposition (very humid).# Covers 37 countries, 15% of the land surface of Africa.
Seismic Activity in AfricaWhat physical
features lie along these
areas of seismic
activity?
West Africa: Home of our Hurricanes
Natural Resources
SOCIAL/CULTURE
Bantu Migrations
1000-1800 AD: Large wave of migrations from W to E Africa.
1st to arrive: The Bantu from the Congo or Niger Delta Basin
“Bantu” = group of people who speak the same/similar language with common word “NTU” , means “a person”
The Middle Passage The portion of
the triangular trade in which millions of people from Africa were shipped to North America as their need for people to farm the land rose.
Slaves were sold, or often kidnapped.
Age-Group Differences Developing vs. Industrialized countries
Education Compulsory in much of
Africa. Obstacles:
Lack of teachers in rural areas
Gov’t spend more $$ on military
Boys education takes priority over girls.
College limited & hard to get into.
Global Water Stress
Health A combination of new diseases and reemerging
old ones is putting the lives of millions of Africans in serious jeopardy. HIV/AIDS
1st case – 1959 in Belgian Congo Reasons for spread:
Multiple partners. Mother-to-child Lack of education & superstitious beliefs
Malaria “silent killer” Spread by the bite of a female Anopheles mosquito Kills 700,000 children every year.
Global AIDS
Religion Animist/traditional
Centered around Creator
