Which of the following major desert systems is classified as a subtropical desert located in southern Africa, characterized by red sand dunes and rich mineral deposits?

💡 Solution & Explanation

The Kalahari Desert is a large semi-arid sandy basin spanning portions of Botswana, Namibia, and South Africa, characterized by extensive red sand dunes formed during drier geological periods. Unlike true hyper-arid deserts, the Kalahari supports various types of vegetation and wildlife due to its higher precipitation levels. The Gobi and Taklamakan deserts are located in Asia, whereas the Patagonian Desert lies in South America. It is rich in mineral deposits, notably diamonds and coal.
