The Great Rift Valley

  1. 1. The Great Rift Valley By: Anthony SanFilippo
  2. 2. Why The Great Rift Valley Is Important To Me <ul><li>The Great Rift Valley is important to me because it is one of the world’s most known natural landmarks, and has some key effects on Africa. </li></ul>
  3. 3. My Essential Question How has the Great Rift Valley effected Africa as a home to animals and humans?
  4. 4. My Burning Questions <ul><li>1. How long has it been around? </li></ul><ul><li>2. Is it currently a major road block/ </li></ul><ul><li>3. How well do animals live together there? </li></ul><ul><li>4. How has human-environment interaction effected it? </li></ul><ul><li>5. How do humans live with the rift valley. </li></ul>
  5. 5. What I already knew about the Great Rift Valley <ul><li>Before researching, I knew two things about the Great Rift Valley. </li></ul><ul><li>I knew that it was formed from a divergent plate boundary in Africa. </li></ul><ul><li>I also knew it will eventually break the continent of Africa into two. </li></ul>
  6. 6. My Research
  7. 7. The Great Rift Valley Profile <ul><li>Age: about 20 million years old </li></ul><ul><li>Length: about 6,000 miles long </li></ul><ul><li>Width: 30-100 km </li></ul><ul><li>Height: hundreds of feet below sea level-6,232 feet </li></ul>
  8. 8. How It Got Here <ul><li>The Great Rift Valley formed millions of years ago. </li></ul><ul><li>It was formed from the divergent plate boundary between the African Plate and the Arabian Plate. </li></ul>
  9. 9. What The Land Is Like There <ul><li>The Great Rift Valley has a diverse landscape. </li></ul><ul><li>It has parts where there is fertile farmland for farmers. </li></ul><ul><li>It has flat arid plains where animals can graze. </li></ul><ul><li>It has places where there is an uninhabitable desert. </li></ul><ul><li>It also has steep escarpments (some 6,000 feet high). </li></ul>
  10. 10. Volcanic Activity <ul><li>The Great Rift Valley has lots of volcanic activity in its area. </li></ul><ul><li>It is home to 30 active or dormant volcanoes including Mount Kilimanjaro (pictured on the left). </li></ul><ul><li>It is also home to hundreds of hot springs. </li></ul><ul><li>Almost all of those “volcanics” thanks to it. </li></ul>
  11. 11. Lakes <ul><li>The Great Rift Valley is home to hundreds of lakes. </li></ul><ul><li>These lakes are formed from water coming into the Great Rift Valley from the Indian Mid-ocean Ridge (they are connected). </li></ul><ul><li>The lowest point of the Great Rift Valley lays at the bottom of Lake Turkana. </li></ul>
  12. 12. Special Lakes <ul><li>The Great Rift Valley has many special lakes of highly concentration of sodium chloride. </li></ul><ul><li>Fish thrive in these waters. </li></ul><ul><li>Birds have been attracted to these lakes for their abundance of fish. </li></ul>
  13. 13. The “Fork” <ul><li>The Great Rift Valley is split into two rifts at one point (Western and Eastern Rift). </li></ul><ul><li>The most notable rift is the Western Rift. </li></ul><ul><li>The Western Rift has high mountains and deep lakes. </li></ul><ul><li>It is also home to the first watersheds of the Nile. </li></ul>
  14. 14. Human Entertainment <ul><li>Humans have been active in the national parks around the valley. </li></ul><ul><li>We have been able to go hiking, rock climbing, mountain biking, and hunting (constricted). </li></ul><ul><li>Thanks to scenic views, we are also able to go sightseeing. </li></ul>
  15. 15. After Research
  16. 16. What Was Most Interesting <ul><li>From my research, I thought that the diversity of the landscape was most suprising. </li></ul>
  17. 17. Questions I Still Have <ul><li>Is the Great Rift Valley currently a major roadblock? </li></ul><ul><li>How have humans lived there? </li></ul><ul><li>Is the breaking up of Africa a big deal? </li></ul><ul><li>What is the Eastern Rift like? </li></ul>
