10. Highland Features Rivers plunge down escarpments making cataracts (waterfalls)Rivers plunge down escarpments making cataracts (waterfalls) Victoria Falls; b/w Zambia & Zimbabwe

11. Highland Features Africa has highest overall elevation than any other continent…Africa has highest overall elevation than any other continent… But still few mountainsBut still few mountains Mts. included in Eastern highlandsMts. included in Eastern highlands –Ethiopian Highlands, and volcanoes Mt. Kilimanjaro and Mt. Kenya

16. Great Rift Valley Stretches from Syria to MozambiqueStretches from Syria to Mozambique Formed by shifting tectonic plates millions of yrs. agoFormed by shifting tectonic plates millions of yrs. ago –Volcanoes & earthquakes continue to shape region TODAY

18. Red Sea

19. Great Rift Valley Forms two branchesForms two branches –Eastern branch = volcanic cones –Western branch= lakes Lake Tanganyika (2 nd lgst. freshwater & 2 nd deepest in world)Lake Tanganyika (2 nd lgst. freshwater & 2 nd deepest in world) Lake Malawi (mt. rimmed, >2,300 feet deep)Lake Malawi (mt. rimmed, >2,300 feet deep) Lake Victoria (2 nd widest in world, but shallow; source of White Nile)Lake Victoria (2 nd widest in world, but shallow; source of White Nile)

20. Lake Tanganyika Lake Malawi

21. Lake Victoria

22. The African Great Lakes

23. Water Systems Lakes & rivers come from basins formed millions of yrs. ago as land upliftedLakes & rivers come from basins formed millions of yrs. ago as land uplifted Travel from plateaus in center of cont. to the seaTravel from plateaus in center of cont. to the sea – Hit escarpments  waterfalls  near impossible to navigate inland/ up river

24. Water Systems Lake Chad:Lake Chad: –West-central Africa 20 mil. ppl in 4 countries depend on it20 mil. ppl in 4 countries depend on it –Faces desertification (droughts + natural climate) So shallow, affected greatly by climate ΔsSo shallow, affected greatly by climate Δs 1960s = 26,000 km²; 2000= 1,500 km²1960s = 26,000 km²; 2000= 1,500 km²

26. Water Systems Lake Volta:Lake Volta: –Man-made (1 of lgst. in world) –Flooded 700 villages & displaced 70,000 to create –Used for irrigation, fishing, hydroelectric power (Akosombo Dam) for major aluminum plant and ppl of Ghana
