The largest desert in Africa is the Sahara Desert. It spans approximately 9.2 million square kilometers (3.6 million square miles) across several countries, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Niger, Sudan, and Tunisia. Known for its vast arid landscapes, sand dunes, and extreme temperatures, the Sahara is one of the hottest places on Earth. The desert is not just barren; it is home to diverse flora and fauna adapted to the harsh conditions. The Sahara has played a crucial role in shaping the culture and history of the African continent.
