It is the largest hot desert of the world and third largest desert overall, after deserts of Antarctica and northern Arctic.

History of Sahara Desert

For many years, the Sahara has alternated between Savanna grassland and desert, in a 20,000-year cycle. This is due to precession of Earth’s axis as it rotates across the Sun. Rotation across the Sun changes the location of North African monsoon.
