The Sahara Desert is located on the continent of Africa. It is the largest hot desert in the world, covering approximately 9.2 million square kilometers, making it nearly the size of the United States. The Sahara extends across many countries, including Algeria, Chad, Niger, and Egypt, and features diverse landscapes, such as dunes, mountains, and rocky plateaus. The climate is characterized by extremely low rainfall, high temperatures during the day, and cooler nights. Despite its harsh conditions, the Sahara is home to various unique flora and fauna that have adapted to survive in this arid environment.
