The Antarctic Desert is the largest desert in the world, covering the continent of Antarctica. Despite being covered in ice, it is classified as a desert because it receives very little precipitation, making it extremely dry. The harsh climate features frigid temperatures, with some areas reaching as low as -80 degrees Fahrenheit. This unique environment is home to various species, including penguins, seals, and krill. The Antarctic Desert plays a crucial role in Earth's climate system, reflecting sunlight and helping to regulate global temperatures. Its vast ice sheets also store about 60% of the world's fresh water.
