What is the largest hot desert in the world?

The Sahara

The Sahara covers much of North Africa, spanning 9 million square kilometers. Despite its extreme temperatures and arid conditions, the desert is home to a surprising variety of life adapted to these harsh conditions, including fennecs, scorpions, and a variety of resilient plants. Rock paintings in some areas of the Sahara testify to a time when the climate was moist enough to support abundant wildlife and human communities. These paintings depict hunting scenes and animals that have now disappeared from these regions, offering a fascinating glimpse into the desert's prehistoric history.
