2nd Largest Continent54 independent nationsMore than 1000 languages spoken
Africa: Geographic Diversity
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
• 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
Place: Topography, Vegetation, & Climate
LOCATION

• 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)
