What Is The Sahara Desert

The Sahara Desert spans approximately 9.2 million square kilometers and is in fact the largest hot desert in the world. Located in North Africa, it covers parts of eleven countries, including Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, Algeria, and Tunisia. This expanse of arid land is characterized by its often harsh climate, with massive temperature swings that can soar above 50 degrees Celsius during the day and plummet below freezing at night.
