Sahara Desert

Explanation:

The Sahara desert is the largest warm desert in the world and the third largest after Antarctica and the Arctic. With more than 9,065,000 km² in area, it covers most of North Africa occupying an area almost as large as that of China or the United States. The Sahara extends from the Red Sea, including parts of the coast of the Mediterranean Sea, to the Atlantic Ocean. To the south, it is bounded by the Sahel, a semi-arid tropical savannah belt that makes up the regions that cover northern sub-Saharan Africa.
