What is the largest desert on Earth, characterized by its extreme temperature variations and limited precipitation?

The largest desert on Earth, distinguished by its remarkable temperature fluctuations and scarce precipitation, is the Antarctic Desert. Encompassing a vast expanse of approximately 14 million square kilometers, this formidable desert comprises the continent of Antarctica. Contrary to popular belief that deserts are solely hot and arid, the Antarctic Desert is categorized as a polar desert due to its exceptionally low temperatures and minimal annual precipitation, which predominantly occurs in the form of snow. The extreme cold, coupled with powerful winds, renders this inhospitable environment nearly devoid of terrestrial life. However, a plethora of marine life, including various species of penguins, seals, and whales, thrives along the coastal regions.
