The continent that is home to the largest desert is Antarctica. While many associate deserts with hot temperatures, the definition of a desert is based on low precipitation levels. Antarctica, a polar desert, receives very little annual snowfall, resulting in an arid landscape covered in ice. Its vast expanse stretches over 14 million square kilometers (5.5 million square miles), making it the largest desert on Earth. Despite its harsh climate, Antarctica supports unique ecosystems and wildlife, including penguins and seals, adapting to its extreme conditions. The continent's significance extends beyond ecology; it plays a crucial role in global climate regulation and research.
