Africa The Great Rift Valley

  1. 1. The Great Rift Valley, Africa Matt Bunker
  2. 2. Essential Question <ul><li>What makes the Great Rift Valley such a geographical phenomenon? </li></ul>
  3. 3. What is It? <ul><li>The Great Rift Valley is a deep trench that runs through vertically through Africa, ranging in width and elevation. </li></ul>
  4. 4. What I Knew <ul><li>I already knew that the Great Rift Valley is located in Eastern Africa. I also knew that a rift is a break in the Earth’s surface that makes a deep trench, made by a force called plate tectonics. I knew that Mount Kilimanjaro is on the edge of the great Rift Valley too. </li></ul>
  5. 5. Why I Chose this Topic <ul><li>The force that created the Great Rift Valley was taught to us in Science class. That made this topic sort of stand out to me because I already had some background knowledge, but I wanted to know more about it. </li></ul>
  6. 6. Formation <ul><li>The Great Rift Valley was formed about 35 million years ago when the Earth’s plates split apart, forming a rift in the Earth’s crust. As the plates continue to drift apart, the Great Rift Valley keeps changing and pulling. </li></ul>
  7. 7. Size <ul><li>The Great Rift Valley is approximately 3,600 miles in length, making it the longest fault system in the world </li></ul><ul><li>It ranges from 19 to 63 miles wide </li></ul><ul><li>Elevation ranges from 1,300 below sea level (at the Dead Sea) to 6,000 feet above sea level (at Southern Kenya) </li></ul>
  8. 8. Landforms <ul><li>Mountains, like Mount Kilimanjaro, Mount Kenya, and Mount Margherita, are located on the edge of the Great Rift Valley. </li></ul><ul><li>Most major lakes of Africa are located near the Great Rift Valley, like Lake Turkana and Lake Nyssa </li></ul><ul><li>About 20 volcanoes are on the Great Rift Valley’s southern edge </li></ul>
  9. 9. Future <ul><li>If the Great Rift Valley continues to grow the way it is, it could be flooded by water, which would form a new gulf or a new sea. </li></ul>
  10. 10. Interesting Information <ul><li>What I think is the most surprising fact was that in the future the Great Rift Valley could become a new body of water. I was also surprised that The Great Rift Valley is the longest fault system in the world. </li></ul>
  11. 11. Questions <ul><li>How long will it take the Great Rift Valley to fill with water when it happens? </li></ul><ul><li>If the Great Rift Valley is filled by water an turns into a gulf or sea, how will this effect the life around it? </li></ul>
  12. 12. Websites <ul><li>1. </li></ul><ul><li>2. </li></ul><ul><li>3. </li></ul><ul><li>4. </li></ul><ul><li>5. </li></ul><ul><li>6. </li></ul><ul><li>7. </li></ul><ul><li>8. Textbook </li></ul>
