"The Sahara is a desert on the African continent. With an area of 9,200,000 square kilometres it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
The name "Sahara" is derived from the Arabic word for "desert" in the feminine irregular form.
It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south it is bounded by the Sahel, a belt of semi-arid tropical savanna." -Wikipedia
