  3. 3. Historical Overview <ul><li>Great empires flourished in northern Africa, the Sahel region, and southern Africa, and the cultures of the Bantus and Muslims spread across parts of Africa. </li></ul><ul><li>After 1500, Europeans traded with Africans along the coast for gold, ivory, and slaves. </li></ul><ul><li>In the 1800s, European colonialism carved up the continent without regard for existing political or cultural divisions, but also brought advantages. </li></ul><ul><li>By the 1960s, most African countries were independent, but remained poor and suffered under civil wars. </li></ul>As the climate became drier, people migrated into lands north and south of the Sahara and into the Nile River valley. 1
  4. 4. Physical Characteristics <ul><li>Most of the continent consists of plateaus, or elevated blocks of land with flat or gently rolling surfaces. </li></ul><ul><li>Southern Africa and the Sahara desert form two plateaus. </li></ul><ul><li>Basins of rivers form low-lying areas on these plateaus. </li></ul><ul><li>The Great Rift Valley in eastern Africa is marked by volcanoes, lakes, and hot springs. </li></ul>Africa’s highest mountains rise along its northern and eastern edges. 2
  5. 5. Climates 3
  6. 6. Climates <ul><li>Arid and Semiarid extend over much of northern, eastern, and southern Africa. </li></ul><ul><li>Tropical wet covers parts of central and western Africa. </li></ul><ul><li>Tropical wet and dry stretches over large parts of Madagascar and western and central Africa. </li></ul><ul><li>Mediterranean lies on coastal parts of northern and South Africa. </li></ul>Physical characteristics and location affect Africa’s climate. 3
  7. 7. Ecosystems 4
  8. 8. Ecosystems <ul><li>Tropical grassland covers most of western, eastern, and southern Africa. </li></ul><ul><li>Desert and desert scrub extends across northern and parts of southern Africa. </li></ul><ul><li>Tropical rain forest lies in central Africa and parts of western Africa. </li></ul><ul><li>Chaparral and temperate grassland stretch across parts of northern and southern Africa. </li></ul>Africa supports a broad range of ecosystems. 4
  9. 9. People and Cultures <ul><li>Africa’s population is concentrated in the Nile Valley, Nigeria, the East African highlands, and some coastal areas. </li></ul><ul><li>Colonialism introduced many elements of European culture to African nations </li></ul><ul><li>Africa’s peoples maintain traditions of storytelling and oral history, or history passed down by word of mouth. </li></ul>Africa is home to a wide range of peoples, languages, and cultures. 5
  10. 10. Economics, Technology, and Environment <ul><li>Subsistence farming is practiced through much of Africa. </li></ul><ul><li>Agriculture faces many challenges, such as leaching and land degradation. </li></ul><ul><li>Manufacturing and trade are important in the largest metropolitan areas. </li></ul><ul><li>Africa is rich in mineral resources, such as petroleum and uranium. </li></ul>Africa’s diverse environment supports a wide range of economic activities. 6
  11. 11. Database <ul><li>Egypt’s Nile River valley has a high population density, with more than 3,000 people per square mile, and severe overcrowding poses the risk of food and water shortages. </li></ul><ul><li>High population density and rapid population growth are causing Nigerian cities such as Lagos to grow rapidly, but most Nigerians still live in rural areas. </li></ul><ul><li>With almost two thirds of the population living in rural areas, Mozambique has a low population density and deaths from the AIDS epidemic slow the population growth. </li></ul><ul><li>South Africa is highly economically developed and urbanized, and has a lower birthrate, but AIDS is also a very serious problem there. </li></ul>7
