  1. Geography of Africa

  2. Second largest continent in the world

  3. 4,600 miles from east to west and 5,000 miles from north to south • 11.7 million square miles, it occupies about one-fifth of Earth's land surface.

  4. Sahara Desert Stretching from the Atlantic Ocean to the Red Sea, the Sahara covers an area roughly the size of the United States.

  5. Deserts are largely unsuitable for human life and also hamper people's movement to more welcoming climates.

  6. Only a small part of the Sahara consists of sand dunes. The rest is mostly a flat, gray wasteland of scattered rocks and gravel.

  7. Kalahari Desert

  8. The largest deserts in Africa are the Sahara in the north and the Kalahari in the south.

  9. Sahel Semiarid region. It forms a transitional zone between the Sahara Desert in the north and the Savanna in the south.

  10. The Sahel has been afflicted by prolonged periods of extensive drought.

  11. Savanna A savanna is a rolling grassland scattered with shrubs and isolated trees

  12. Savanna throughout the world

  13. Not enough rain falls on a savanna to support forests. Savannas are also known as tropical grasslands. 

  14. Africa's savannas include plains, mountainous highlands and swampy tropical stretches. • Covered with tall grasses and dotted with trees, the savannas cover over 40 percent of the continent.

  15. Tropical Rain Forest Sometimes called “nature's greenhouse,” it produces mahogany and teak trees up to 150 feet tall. Their leaves and branches form a dense canopy that keeps sunlight from reaching the forest floor.

  16. Mt. Kilimanjaro

  17. Great Rift Valley

  18. The Rift Valley was formed by violent subterranean forces that tore apart the earth's crust. • These forces caused huge chunks of the crust to sink between parallel fault lines and force up molten rock in volcanic eruptions. • Evidence that this process, called rifting, is still in progress comes from the many active and semi-active volcanoes, located along the Rift. • Olduvai Gorge, in Tanzania is one of the most important sites for the study of human evolution. It was the site of a large lake 500,000 years ago.

  19. Atlas Mountains

  20. Mt. Kilimanjaro: Highest free-standing mountain in the world.
