Which desert is the largest hot desert in the world?

The Sahara Desert is indeed recognized as the largest hot desert in the world. It spans across North Africa, covering an area of approximately 9.2 million square kilometers (about 3.6 million square miles). The term "hot desert" refers to regions characterized by extremely high temperatures, particularly in the summer months, alongside limited precipitation.

The vast size of the Sahara and its extreme climatic conditions contribute to its designation as a hot desert. It is bordered by various other geographical features, making its ecosystem diverse in flora and fauna. Its extensive sandy and rocky landscapes, alongside oases that support life, illustrate the unique characteristics that define the Sahara.

In comparison, while the Kalahari Desert is significant in Southern Africa and the Arabian Desert stretches across the Arabian Peninsula, neither of these deserts matches the Sahara in size. The Gobi Desert, located in northern China and southern Mongolia, is also classified as a cold desert due to its harsher winters and higher elevation, further differentiating it from the classification of hot deserts. Thus, the Sahara holds the title as the largest hot desert globally, making it the correct answer.
