What is the name of the desert located in northern China and southern Mongolia that was part of the Mongol Empire?

The desert located in northern China and southern Mongolia that was part of the Mongol Empire is known as the Gobi Desert. This geographic region is significant not only for its vast arid landscapes but also for its historical importance as a critical area during the time of the Mongolian Empire, which flourished under leaders like Genghis Khan. The Gobi has played a vital role in the history and culture of the region, serving as a barrier between the fertile lands in the south and the steppes in the north, making it a strategic area for trade and military operations. In contrast, the other deserts mentioned have different geographic locations and characteristics: for instance, the Atacama Desert is located in South America, the Namib Desert is in Africa, and the Sahara Desert stretches across North Africa. These distinct locations illustrate why the Gobi Desert is the correct answer in this context.
