Biggest Desert
The biggest desert in the world is Antarctica, covering about 14 million square kilometers. Despite being covered in ice, it qualifies as a desert due to its extremely low precipitation levels. Antarctica is even larger than the Sahara, which is the world’s largest hot desert. Its vast, icy expanse makes it the largest and most inhospitable desert on Earth, holding the world record for size among all deserts.
