The largest desert in the world is the interior of Antarctica. This has an area of about 14,000,000 km2 (5,400,000 sq mi). Rainfall in the Antarctic interior is extremely low, down to 20 millimeters (0.8 in) per year. This is partially because it is so cold that all liquid water quickly freezes solid and joins the ice pack.
Antarctica is the world's largest desert due to its very low rainfall and massive area. Hot deserts are all over the world, extending into the USA, South America, Africa, Europe, Australia, and Asia.In many places, mostly in Australia and Asia.here are many types of biomes. Rainforest biomes, Tundra biomes, Savanna biomes, Grassland biomes, Taiga biomes, Temperate biomes and Desert biomes. So, basically, when you are talking about a desert biome, you're talking about all the deserts on Earth.
