AFRICA 2nd Largest Continent 54 independent nations More than 1000 languages spoken
Location: Position on Earth’s Surface • Relative: Centrally Located – Interconnected • Exact: 80+% between tropics Cancer and Capricorn
Place: Physical/Human Characteristics: Lakes and Rivers • Major source of transportation and communication • Transportation routes often developed along river valleys. • Escarpments and rapids make some rivers unnavigable • Provide food and irrigation for crops • Population density is higher near water sources
Place: Topography, Vegetation, & Climate • Majority of continent: plateau- high flat raised land • Escarpments- steep cliffs (off sides of plateaus) • Cataracts- Waterfalls over escarpments • 80% of Africa has tropical climate – Between Capricorn and Cancer • Rainy season in north and dry season in the south
Human-Environment Interactions • Aswan Dam: Across the Nile River in Egypt • Suez Canal- man made waterway in Egypt connecting the Mediterranean and Red Seas • Desertification: turning semidesert to desert (Sahel south of Sahara) • Leaching- process of heavy rains washing nutrients from soil
