In the northern parts of Africa, the Sahara Desert is one of the largest deserts in the world. It spans over 9 million square kilometers, covering countries like Algeria, Libya, Chad, and Sudan. Despite its harsh and arid conditions, the Sahara is home to a variety of wildlife and plant species that have adapted to survive in this extreme environment. Many nomadic tribes inhabit the desert, relying on the limited resources available to them for sustenance. The climate is extremely hot during the day while temperatures can drop significantly at night.
