What are the Top 10 Deserts in the World?
Deserts are some of the most fascinating landscapes on Earth, known for their extreme conditions and unique ecosystems. The top 10 deserts in the world vary in size, climate, and biodiversity, offering a glimpse into the diverse environments that exist across our planet.
What Defines a Desert?
A desert is characterized by its arid conditions, receiving less than 250 millimeters (10 inches) of precipitation annually. These environments can be hot or cold, with vast stretches of sand dunes, rocky plateaus, or even icy surfaces.
