The hottest desert in the world is known as the Great Sand Desert, which encompasses areas of the Sahara Desert in Africa. The temperatures can rise dramatically, often exceeding 50 degrees Celsius (122 degrees Fahrenheit) during the day. This harsh climate, characterized by minimal precipitation and extreme heat, results in sparse vegetation and a unique ecosystem. The Sahara is not only a geographical feature but also a cultural landscape, home to various tribes and wildlife, and serves as a critical area for scientific research on climate change and desertification.
