The Sahara desert is located across Northern Africa and covers approximately 10 percent of the African continent. Its borders include the Mediterranean Sea to the north, the Atlantic Ocean to the west and the Red Sea to the east.
The Sahara Desert stretches across several countries, including Western Sahara, Mauritania, Morocco, Mali, Algeria, Tunisia, Libya, Chad, Egypt and Sudan. The desert is largely undeveloped and consists of a variety of terrains, such as sand dunes, barren rock plateaus, salt flats and wind-swept plains. In the south, the desert gradually gives over to wetter lands in the area known as the Sahel. Directly south of the Sahel is the Sudanian Savannah.
