The Sahara Desert is primarily located in Africa. It stretches across several countries, including Morocco, Algeria, Tunisia, Libya, Niger, Mali, Chad, Sudan, and Egypt. Covering approximately 9.2 million square kilometers, it is known for its vast expanses of sand dunes, rocky plateaus, and unique ecosystems. The Sahara plays a crucial role in the climate and biodiversity of North Africa, influencing weather patterns and supporting a variety of flora and fauna adapted to its harsh conditions.
