The Sahara Desert is the largest hot desert in the world, spanning approximately 9.2 million square kilometers across North Africa. It is known for its vast stretches of sand dunes, rocky plateaus, and extreme temperatures, which can soar above 50 degrees Celsius during the day and drop significantly at night. Home to diverse ecosystems, the Sahara supports various wildlife, including camels, foxes, and numerous bird species. Despite its harsh conditions, the desert has been inhabited for thousands of years, with ancient trade routes and cultures emerging in its oases, showcasing the resilience of life in one of the planet's most challenging environments.
