The world's largest hot desert is the Sahara Desert, which spans across North Africa. Covering an area of approximately 9.2 million square kilometers, it is known for its vast expanse of sand dunes, rocky plateaus, and extreme temperatures. The Sahara is characterized by its arid climate, receiving very little rainfall, which makes it one of the most inhospitable environments on Earth for many forms of life. Despite its harsh conditions, the desert is home to diverse flora and fauna, as well as human communities that have adapted to survive in this striking landscape, rich in history and culture.
