(DESCRIPTION)

A blue hexagon appears in the middle of a gray background split into two halves by a line, A banner is outlined in light blue for the title, Myth vs Reality. An illustration with sea serpents surrounding a ship is above Myth, a satellite view of a desert landscape is above Reality. The Myth side is highlighted. Text, All deserts are sandy places with dunes.

 

The Reality side is highlighted. Text, Only 20% of Earth's desert land is covered with sand. Much of Earth's deserts are wind-swept plains of exposed bedrock, gravel, and hard desert soils, with no sand dunes. The largest desert on Earth, Antarctica, is largely covered in ice.
