The desert located primarily in northern Africa is the Sahara Desert, the largest hot desert in the world. Spanning over 9.2 million square kilometers (3.6 million square miles), the Sahara extends across several countries, including Algeria, Libya, and Egypt. Its landscape includes vast sand dunes, rocky plateaus, and sparse vegetation, with extreme temperature fluctuations between day and night. The Sahara is home to various nomadic tribes and wildlife adapted to arid conditions, contributing to the region's unique cultural and ecological diversity.
