paid off http://www.buzzle.com/articles/sahara-desert-plants.html sup Spotted Hyenas go to google docs please Philip's Encyclopedia 2008 The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide The Columbia Encyclopedia Columbia University Press http://www.credoreference.com/entry/columency/sahara Barbary Sheep Barbary sheep originated in the Sahara desert. The Barbary sheep live in the mountains of North Africa.
The Barbary sheep have adapted to the desert by being able to go for a long time without drinking more water, because they use inner water. They have curly horns. Most sheep have one lamb, but twins are also normal. Barbary sheep are herbivores and eat grasses and small shrubs. http://animaldiversity.ummz.umich.edu/accounts/Ammotragus_lervia/ The African Peyote Cactus The African Welwitchsia This plant has very long roots to get more water from the ground. The african Welwitchsia has been known to live a long time. Picture of a Tamarisk Tree Picture of the Screwhorn Antelope Picture of a Doum Palm (they apparently carry fruit!!!!!) How the Sahara was Formed The Sahara was once a large grassland that held a large amount of life. It turned into a desert because of a devastating desertification change. Over at least 300 years of desertification it stopped raining and wildlife had to move.
Scientists at Potsdam Institute say it was the most dramatic change in 11000 years. To Tuaregs, their souls always rest in their bodies, except when they are sleeping. While they sleep, the Tuaregs believe that the soul is free to travel wherever it feels. http://www.everyculture.com/Africa-Middle-East/Tuareg-Religion-and-Expressive-Culture.html What is the Sahara desert like? It has two main rivers: the Nile river and the Niger. Although it is typically thought of as having many sand dunes, it is only 15% covered in the stereotypical dunes. Other features in the Sahara are mountains, plateaus, and plains. The hottest temperature in the Sahara ever recorded was 136 degrees Fahrenheit.
In the Sahara there are many mountain ranges and some are volcanic.
It lies between the equatorial trade winds in Northern Africa. What we would do in the Sahara Go to Egypt and visit the Giza Pyramids. The Giza Pyramids were built around 4500 years ago. The first was the Great Pyramid of Khufu. http://www.onepiecetravel.com/AFRICA/Cairo--Egypt_162.html http://science.nationalgeographic.com/science/archaeology/giza-pyramids See the Tuareg and learn their customs. The Sahara gets smaller and larger all the time. Even in the Sahara's wetter areas, they can go without rain for years. The desert is so huge that voyagers can look for days without finding an oasis. Camp out with a lot of blankets and jackets and rations and a fan to see what a night in the desert is like. http://www.placesonline.com/africa/mali/attractions.asp Visit the highest floor in the Cairo Tower and view the Pyramids and the Nile river in a telescope from high above. I'd also want to eat at 360 Revolving to see more of Cairo. Thanks for watching! END OF PREZI!!
