The Sahara Desert is the largest hot desert in the world, covering about 9.2 million square kilometers in North Africa. It stretches across several countries, including Egypt, Sudan, and Algeria. The desert is known for its vast sand dunes, rocky plateaus, and extreme temperatures, which can soar above 50 degrees Celsius during the day and drop significantly at night. Despite its harsh conditions, the Sahara is home to unique wildlife and plants adapted to survive in arid environments. Animals like the Fennec fox and dromedary camel thrive here, while nomadic tribes, such as the Tuareg, have lived in the desert for centuries, relying on its resources for their livelihoods.
