The Sahara Desert is the name given to a large desert in Northern Africa, extending from the Red Sea in the east through Sudan and Mauritania in the west. It is also known as "The Great Sand Sea".
Extreme heat makes much of the region completely uninhabitable, but there are some oases in which people have set up homes. Much of the desert is flat plains surrounded by high mountains, with sand dunes along some parts. There are also two mountain ranges in this desert: Atlas Mountains in Algeria and Tunisia, both separated by an extensive valley. The highest point here is Mount Koussi at 5,211 m above sea level.
Over 1000 different species of plant life can be found here, some of which can be seen below
