Image Caption: Two great sand seas occupy northern Algeria, Grand Erg Oriental (Eastern Sand Sea) and Grand Erg
Occidental (Western Sand Sea). Both sand seas occupy depressions that are separated by a north-south rise
called Mizab. Ergs are areas of large accumulations of sand that take the form of actively shifting dunes,
fossilized dunes, or extensive sand sheets.
