The geographic feature known as the Sahara Desert is the largest hot desert in the world, covering much of North Africa. Spanning over 9 million square kilometers, the Sahara exhibits a harsh climate characterized by extreme temperatures and minimal rainfall. Despite its arid conditions, the desert supports a variety of flora and fauna adapted to survive in such an environment. The Sahara holds significant cultural and historical importance as well, having been a crossroads for trade and migration for centuries.
