The Sahara is the world's largest desert, covering an area of over 3.5 million square miles. It is characterized by its ARID climate, with temperatures often reaching over 100 degrees Fahrenheit. The Sahara is also known for its vastness, with some areas stretching for hundreds of miles without any signs of life. It is also incredibly DRY, with little to no rainfall in most areas. Finally, the Sahara is known for its SANDY terrain, with VAST stretches of sand dunes and rocky plateaus. All of these characteristics make the Sahara a place that is like no other on Earth.
