The Sahara Desert is located in Africa, covering a significant portion of North Africa. It is the largest hot desert in the world and is characterized by its vast stretches of sand dunes, rocky plateaus, and sparse vegetation. Countries such as Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, and Tunisia share parts of the Sahara. The climate is predominantly arid, with extreme temperatures ranging from scorching heat during the day to cooler nights, and minimal annual rainfall. The desert is also home to various flora and fauna that have adapted to these harsh conditions.
