The name of the large desert located in northern Africa is the Sahara Desert. Spanning approximately 9.2 million square kilometers, it is the largest hot desert in the world. The Sahara stretches across several countries, including Algeria, Libya, Egypt, Mali, Niger, Chad, Sudan, and Mauritania. Characterized by its vast sand dunes, rocky plateaus, and arid climate, the desert experiences extreme temperatures, with scorching heat during the day and relatively cooler nights. Despite its harsh conditions, the Sahara is home to diverse ecosystems and wildlife, as well as interests in studying ancient cultures and archaeological sites that provide insights into human history.
