The Sahara

suh-HAR-uh or suh-HAIR-uh
Also Known As as-Sahra al-Kubra, Arabic for "the greatest desert"
Deserts

The largest hot desert in the world, spanning most of North Africa from the Atlantic coast to the Red Sea. Its terrain varies far more than the popular image of continuous dunes: rocky plateaus and gravel plains cover most of its area, with sand seas, or ergs, concentrated in particular basins. Its extent has fluctuated significantly over geological time, including a well-documented humid green period roughly six to eleven thousand years ago.
