Every one know that the Sahara desert is the world's largest hot desert - a vast ocean of sand where the heat is so terriable that men and animals die of thirst. But it was once beautiful, green and fertile place. Scientist belive that around 10,000 B.C., the Earth's orbit wobbled slightly, causing a shift in weather patterns. The monsoons which drench Southern Africa to day shift up, pouring water into the Sahara, where it forrmed bodies of water. plant life flourished and plants were followed by animals and humans, who established lively civilizations. When weather pattern shifted again, the Sahara turned to being a desert once more.
because i am that awesome, that i was there then
The Western Sahara was once known as the Spanish Sahara.
Climate change (mainly) and progressive "desertification" through poor farming practices and over grazing
An oasis or the Nile River Valley.
The Saheel
the climate allows for fertile soil and vegetation
Because plants won't grow without water - if plants once grew in the Sahara then there must have been water there.
Water once flowed in the Sahara. Hopeed i helped.
The area around the Nile is called called the fertile strip
The Nile River passes through the Sahara Desert of North Africa.
The Sahara Desert is expanding. This means it is encroaching upon otherwise good, fertile land. Poor agricultural practices along its southern borders have resulted in increased desertification, so grassland to the south of the Sahara is disappearing at the rate of 50 km every year.
The Sahel is a region of semi-arid grassland between the Sahara and the Savanna.
