What Defines a Desert?

Deserts are often characterized by their arid conditions, receiving less than 250 millimeters (10 inches) of precipitation annually. However, there's more to a desert than just dryness. These regions are typically known for extreme temperature variations, both seasonally and diurnally. During the day, temperatures can soar to blistering highs, while nights can be surprisingly cold. The largest desert in the world exemplifies these characteristics, presenting a challenging environment for life to thrive.

Beyond climatic conditions, deserts are also defined by their unique landscapes. These can range from sandy dunes and gravel plains to rocky plateaus and salt flats. The geological processes that shape these landscapes are ongoing, influenced by wind, water, and tectonic activity. This dynamic environment creates a diverse range of habitats, each supporting distinct ecosystems.

Which is the Largest Desert in the World?

The title of the largest desert in the world is often attributed to the Antarctic Desert.
