In this article, we’ll explore the top 10 largest desert areas on Earth. The Antarctica Desert claims the title of the largest desert globally, covering an expansive 14,200,000 square kilometers in Antarctica. Interestingly, while water dominates Earth’s surface with a ratio of 2:1 over land, deserts constitute a significant portion, spanning 33% of the planet’s land area and 9.5% of its total surface. Let’s delve into the fascinating world of these vast, arid landscapes.
What is a desert?
Deserts are typically arid areas characterized by scarce precipitation, usually less than 12 inches annually. They form when prolonged drought conditions arise from shifts in regional climate patterns.
Types of deserts in the world:
There are 4 types of deserts in the world
