The continent known for having the largest desert is Antarctica. While many associate deserts with hot climates, a desert is defined by its low precipitation levels. Antarctica, typically covered in ice, is considered a polar desert, receiving less than 10 inches of precipitation annually. Its extreme cold and unique landscape create a stark, vast environment that is mostly uninhabitable. The Antarctic Desert is crucial for global climate regulation and serves as a significant area of scientific study, particularly regarding climate change and its impacts on ice sheets and global sea levels.
